EPC crunch might limit 2024 utility scale solar growth

He guesses that the top 10 EPCs represent 15-18GW of overall capacity and 80% of the EPC industry, suggesting the overall EPC capability could be just 21GW. Our contact shared that “supply chain issues continue to push things to the right. A lot of projects are pushing to the right. [He doesn’t think] 2024 is going to be +30% y/y. 2024 could flat to up 5% only.” EPCs in the recent past “took on crazy work in past years” and now the [EPC] focus is on improving the bottom line Recently, we wrote here that EPC capacity could be a new bottleneck. We asked our contact about EPC bottlenecks and what the latest dynamics are. Some EPCs have exited the business, such as Ames Construction, which represented 1-1.5GW of annual capacity. There were credible Tier 1 EPCs that took on projects that were losing money, thinking they “could turn it around but labor quality has not been good and margins are bad.”

US solar up 75% – 35 GW new capacity deployed in 2023

The US utility-scale solar sector added 23.7GW of new capacity, alongside 11.6GW of capacity in the commercial and industrial and residential rooftop sectors.

35.3GW of new solar capacity in 2023

42GW of new renewable power generation capacity, alongside 35MW of new biomass and waste-to-energy capacity

new wind installations, which accounted for around 7GW of new capacity

China overtook the US to become the largest storage market in the world, despite developers commissioning 7.5GW of new battery storage facilities in the US

In the first 11 months of 2023, the US imported over 50GW of PV modules, an increase of 144% over the same period in 2022

Analysts from BloombergNEF note that the US has US$469 billion in “overcapacity investment” planned over the next three years

Texas (45%) & California (36%) deploying 80% of US’ 2024 utility batteries

Developers are expected to complete 6.4 gigawatts of new grid battery capacity in Texas this year, according to the federal Energy Information Administration. That’s more than double the 5.6 gigawatts of battery capacity it ended 2023 with.

much battery capacity as the entire United States built last year

The projection outpaces the 5.2 gigawatts set to come online in California.

The U.S. is slated to add 14.3 gigawatts of battery storage overall this year.

200 MWac

374 MWdc solar installation coupled with 150 MW/600 MWh of energy storage, is currently in the early stages of construction and is slated to commence operations in the first quarter of 2025

announced the procurement of over $1 billion in aggregate financing commitments for its Eland 2 Solar-plus-Storage Project in Kern County, California.

Tesla’s Megapack 2 XL battery system

SOLV Energy, based in San Diego, serves as the project’s engineering, procurement, and construction (EPC) contractor


Back in September 2019, 8Minute Solar said their Eland Solar & Storage facility would have a 60% capacity factor.

In 2022, he reiterated this value in an interview:

We also created the Eland Solar & Storage Center, the first large-scale solar power plant with a 60% capacity factor — twice the natural capacity factor of the sun.

We found optimal economics hovered at around a 60% capacity factor and designed a power plant to meet the customer’s needs.

Skeleton Creek Energy Center

2020, the project’s wind energy portion was completed and is operational, with a capability of generating up to 225 megawatts

solar and storage that could generate up to 250 megawatts of local solar energy to pair with a 252-megawatt, four-hour battery storage system

solar and battery storage portion of the project will bring an estimated $65 million in additional tax revenue

likely will break ground this year and open the facility in 2025


From prior reporting,

The Skeleton Creek combined project is expected to generate about 1.8 million megawatt hours of electricity annually – suggested a mixed AC capacity factor of 41%.

That’s at 500 MWac – but if we’re looking at all three projects outputting from the same general area, it turns into a potential 82% capacity factor.

The U.S. Department of Energy defines the Skeleton Creek Energy Center in its 860M form as a multi-powered 250 MWac wind facility.

Also, date slipped…

Skeleton Creek Solar – 250 MW of solar energy, expected to begin operations by the end of 2023

Skeleton Creek Storage – 200 MW, 4-hour battery energy storage project, expected to begin operations by the end of 2023

Project total power capacities:

250 MW wind generators (or maybe 225 MW)

250 MWac / 325 MWdc est solar

250 MW / 1,000 MWh battery

So, 250 MWac interconnection, 750 MW energy delivery potential, and 1,575 MW of hardware.

50 MW project rejected on technicality

Local authorities are only permitted to give permission to solar power stations up to a certain size (50MW) – and the judge agreed that the Burnhope plans exceeded that size.

Confusing to me because Lighthouse BP knows the local rules (50 MW allowed), 92 hectares is just about enough for 50 MW, and a prior article suggested the site was 49.9 MW.

I assume the project will be submitted again.

Maybe there’s a battery there…I’ll follow up.


50% battery price drop knocks $840 off EVs, more coming

50% battery price drop knocks $840 off EVs, more coming

Several automakers will switch to the CATL cell in mid-2024 at a price not exceeding RMB 0.4/Wh ($56/kWh), according to the report.

The average price of square LFP cells at the same time last year (late June/July) was around RMB 0.8 to RMB 0.9 per Wh. By August 2023, that price was reduced to around RMB 0.6 per Wh.

Each RMB 0.1/Wh ($14/kWh) drop in the price of the battery cells means that a model equipped with a 60-kWh battery pack can save about RMB 6,000 ($840) in costs, the 36kr report noted.

Power batteries have gone from being in tight supply to being in oversupply in a year’s time, and prices are now gradually dropping towards RMB 0.3/Wh, the report said.

Leapmotor’s Cao even believes that the price of battery cells could drop to RMB 0.32/Wh.


Prices were at “RMB 0.9 to 0.8” last June-July, they’re now at “below RMB 0.5”. That’s an 8 month 40-46% price drop.

Buyer suggests prices could hit RMB 0.32 by same June/July – which would be a 60-64% price drop in twelve months.

With increasing technology embedded.

Solar module warranty claims 101

The first is simple: Read the warranty exclusions. When manufacturers face warranty claims, they have two practical options: 1) honor the warranty; or 2) blame everything other than the warranted product for the problem.

Second, system owners also need to organize their essential documentation. This means not only the contract, but also all exhibits to the contract, plus any proposals, purchase orders or documents referenced in the contract even if not specifically made an exhibit.

Third, system owners should also review the O&M plan. Experienced operators might have a great plan in place already, but if it doesn’t consider the specific requirements from the module manufacturer, that gap between what one typically does and what that manufacturer recommends might well be a legitimate basis for a denied warranty claim.

Document that the plan is actually being implemented — make sure, for example, that if a manufacturer recommends yearly re-torquing of bolts on the slew drive, not only is re-torquing done, but it’s also documented as being completed on schedule and according to the manufacturer’s specifications.

Other considerations:

• Plan to pursue warranty claims as quickly as possible. Obviously, this will need to be done while still following any mandated warranty procedures and not spoliating any evidence, but a manufacturer that unnecessarily delays and asks for more and more information to “better assess this claim” is unlikely to do an about-face and honor the warranty claim many months into the process. They either value their customer and want more business in the future (and will therefore meaningfully assess and honor valid warranty claims) or they don’t.

• What are the warranties on all the key systems? Do the modules, tracking system and inverters all have different length warranties? If they don’t all have the same warranty duration, has this been appropriately priced into O&M budgets?

• Who actually holds the warranty? Did the EPC contractor purchase everything? Has the warranty been appropriately assigned, or will the EPC contractor stand in the shoes of the manufacturer? Injecting more parties into the process is going to make things worse — particularly if the remedies available to the owner are not perfectly back-to-back.


Free used solar panels in Orlando

808 partly used solar panels belonging to the county, each 2.6 feet by 5.2 feet, 33 pounds and rated at 175 watts, are to be handed out from February 26 through March 31 at no charge to residents, businesses and whoever else wants them – in Orlando, Florida.

Roselund (CEA) sees 35 GW module capacity in US at end of ‘24

Annual module capacity in the US is expected to reach 35GW by the end of the year.

Last year, large-scale PV module assembly plants from eight manufacturers, representing over 20GW of new capacity, received equipment.

A truly awesome volume of US PV module factory announcements has followed the passage of the IRA — more than 140 gigawatts of annual capacity at last count.


Top renewable company hates renewables

United States’ top developer of green energy has spent nearly six years undermining a clean power project.

NextEra’s campaign has delayed the power line’s construction for almost two years.

“It just shows you that these companies are not fundamentally allied with the climate movement, not fundamentally on the side of climate progress,” said Leah Stokes.

NextEra’s national fleet of wind and solar farms generate more renewable electricity than any other company in the country.

‘Disturbing evidence’

groups were directed by consultants working on behalf of NextEra

One of the groups, Alpine Initiatives, failed to register as a political action committee before making a $150,000 contribution to the Maine Democratic Party, a move that ethics officials said masked the source of payment from the public. The contribution was an attempt to ingratiate the consultants to Democratic officials as they looked for allies in their fight against the power line, the commission said.

second group led by NextEra-hired consultants, $50,000 for failing to register as a ballot committee after it hired field workers to gather signatures needed to place a question on the 2020 ballot that asked voters to block the line

NextEra spent more than $20 million to support this question, while Avangrid and Hydro-Québec, the Canadian utility that would send power to New England, put up more than $50 million in an attempt to defeat it.

Argued that the client would face “reputational harm” if the consent agreement identified it.

NextEra is the most valuable publicly traded power company in the country, with a market capitalization around $117 billion, and has pledged to achieve “real zero” emissions by eliminating carbon dioxide pollution from its operations by 2045.

3,200% rooftop solar growth projection wrong (or too soon)

The US rooftop solar industry had room to grow by more than 3,200%, he said, leaving companies like his primed to reap the rewards.

The company, which primarily sells rooftop systems, fired workers to cut costs and had to raise $200 million to ease a cash crunch.

75% plunge in shares over the past year, Faricy’s predecessor returned as executive chair this week.

The company in October said it had overstated the value of components of microinverters — small devices that help solar systems produce more energy — and needed to restate financial statements for 2022 and the first and second quarters of 2023.

Island town seeking solar plus storage resilience

Chilmark could pursue three levels of resiliency

most resiliency would be achieved with a full microgrid. This involves powering the town hall, fire, and EMS buildings with solar energy, adding a battery, and connecting all of these features in a microgrid.

could also choose to simply outfit the buildings for solar energy and add a battery. Adding a battery for the buildings could lower electricity costs for solar energy, and would add resilience for outages of up to 48 hours

path of least resiliency, which would provide one to four hours of backup power in the event of a power outage.

With a battery, 15 diesel generators down-Island, used during peaks in power, could also be discontinued.


Residential VPP PPA

Residential finance company sees savings due to VPP

finance package for residential solar-plus-storage, claiming its enhanced terms are directly tied to the benefits derived from virtual power plants (VPP).

Solrite Energy’s PPA is now accessible to homeowners in California, Puerto Rico and Texas. The company is planning expansions into New York, New England and Hawaii later this year

For example, in Massachusetts and Rhode Island, the National Grid’s ConnectedSolutions program seeks to pay energy storage owners up to $400/kW during high grid demand events in Rhode Island, and $225 in Massachusetts. Similarly, Eversource, another major utility in Massachusetts, offers a similar program.


VPP revenue lowering solar pricing

100,000 solar-charged batteries are already installed at California homes and businesses, adding up to nearly 1.7 gigawatts of capacity.

Sunrun project, launched last year, combined 8,500 residential solar-plus-storage systems to consistently discharge an average of just under 30 megawatts of battery power from 7 to 9 p.m. every weekday from August through October


Wind repowering possibly 50% of capacity work this year, 10-20% output bump

Wind developers plan to add some 6.5-7.5 GW of energy to the grid through repowering projects in 2024.

Repowering could account for nearly half of all new wind additions to the grid in 2024.

Advances in wind turbine technology mean replacing outdated equipment with new equipment could boost a wind project’s output by some 10%, Wilmot said. Factor in degradation from aging materials, and you could add another 5% to a wind farm’s productivity. That means repowering could add 10-20% more capacity to the average wind installation built in 2012 or earlier, he said.


Battery records set as prices swing on Australian grid

wholesale market price hit the market floor of minus $1,000 in the morning (around 9.30am grid time) before surging in the late afternoon to the market cap of $16,600 as solar and wind output dried up as the sun went down on a hot Adelaide day.

the discharge of the state’s growing fleet of big battery storage units hit a peak output of 367 MW, beating the previous record of 340 MW set in September last year.

Long lasting “Triple-junction perovskite–perovskite–silicon solar cell” – breaking efficiency records

A group of researchers led by Germany’s Karlsruher Institut für Technologie (KIT) has fabricated a triple-junction perovskite-perovskite-silicon solar cell that achieved a record-breaking efficiency of 24.4%.

The triple-junction cell is based on a perovskite top cell with an energy bandgap of 1.84 eV, a perovskite middle cell with bandgap of 1.52 eV, and a silicon bottom cell with a bandgap of 1.1 eV. The device achieved an open-circuit voltage of 2.84 V, a short-circuit current of 11.6 mA cm–2, and a fill factor of 74%.

The cell was also able to retain 96.6% of the initial efficiency in dark storage aging at 85 C for 1,081 h.


World’s largest solar panel maker buying U.S. silicon

LONGi has contracted Ferroglobe of the UK to supply it with high-quality quartz and silicon.

The agreement came into force on January 1, 2024. No other details of the quantity, the duration or the financial terms of the deal were disclosed.

Ferroglobe currently has quartz operations in Alabama, US. In October 2023, it acquired a high-purity quartz mine in South Carolina, US with capacity to produce over 300 kt/year with more than 10 years of reserve life. Production is scheduled to begin in H2/2024.


Strata secures $559 Million for 1GWh Battery

Strata Clean Energy (Strata), a leading developer, owner, and operator of renewable energy projects, has closed on a $559 million financing for the construction and ownership of the Scatter Wash battery storage complex. The 255MW/1,020MWh storage facility broke ground on January 18 and is expected to be operational by April 2025.

Tesla’s Megapack 2XL, a fully integrated battery system featuring advanced battery technology, software, and power conversion systems, will be used throughout the project.

Strata Clean Energy entered into a 20-year tolling agreement with Arizona Public Service (APS) for its 255 MW / 1 GWh Scatter Wash battery storage complex located in Phoenix.

US firm has extended its domestic content and capacity development programme in the Kingdom, engaging a range of local partners to provide raw material and manufacturing support for its trackers at plants across the region.


“No proven commercial model” for co-located solar and storage projects

From the UK:

“People recognise the benefits of co-located projects”, he said, whether it’s shared infrastructure and grid connections or the gradual increase of revenues and capacity that can be generated from a co-located project, “but I think the actual commercial model is still not very well-understood”.

“There is not really the recognition of having a hybrid asset in itself. The market signals for battery storage are really for standalone projects…because the market is so well-developed.”

“We ask developers to put more effort in when they’re bringing a co-located solar asset to the market – that they don’t give you a ready-to-build solar asset and draw some boxes on it and say it’s a co-located asset. Because you can’t value that.”

AC co-located projects can offer more value than DC, as there is a clearer route to market for ancillary services and corporate power purchase agreements are easier to acquire.


$80 million solar tax credit transfer funding solar electricity purchase

Schneider Electric SE will pay $80 million to acquire tax credits, which in turn will help fund four Engie North America projects that are slated to come online in Texas this year.

Schneider will then use the tax savings to buy 110,000 megawatt hours of renewable energy credits annually — for an undisclosed amount — from Engie’s projects over 10 years.


“(Solar) looks like trash, it doesn’t look very good.”

Amherst County, Virginia officials are proposing to cap such uses at either 50 acres or 10 megawatts of electricity generated in the zoning ordinance.

The discussion came after a Virginia Senate committee carried over for a year Senate Bill 567, a measure that would have taken oversight of 50-megawatt solar facilities out of local governing bodies’ review and into the purview of the State Corporation Commission.

“I don’t want to see solar panels all over the county. It looks like trash, it doesn’t look very good.” – Amherst County Supervisor David Pugh


Rooftop solar can cover 45% of USA’s electricity needs

Environment America modeled the viable technical potential for rooftop solar in the United States, finding that it can serve 45% of U.S. electricity demand based on 2022 levels. In 2022, rooftop solar generated about 1.5% of the total electricity consumed.

Over 3.9 million American households have opted to move forward with rooftop solar.

The data used to generate this logic is based on research by the National Renewable Energy Laboratory, and US Department of Energy group.


California approves massive 2030 solar and storage goals

new goal from the California Public Utilities Commission would also require the state to build more than 56 GW of additional clean energy generation, including solar, different durations of energy storage, as well as 4.5 GW of offshore wind, according to the agency.

The portfolio would have the state add 19 GW of solar, 15.7 GW of four-hour lithium-ion batteries, 2.8 GW of eight-hour lithium-ion batteries and 0.5 GW of long-duration storage along with the 4.5 GW of offshore wind, by 2035.


Big four – Jinko, Longi, Trina, and JA Solar – 60% of solar modules globally

The gap stood at 20 GW between leading companies and those ranked from the fifth in 2022, and then the gap widened to 30 GW in 2023 with 60 GW difference between the first fourth and the rest. It’s estimated that the top four companies took up around 60% of the total shipments of the top-10 list.

The lowest volume reached 20 GW among those ranked fifth to eighth. Companies outside of the rankings, including Suntech, Solargiga, Q-Cells, Huansheng Solar and Seraphim, saw shipment volume rising to 7-10 GW.


Green hydrogen manufacturing outpacing demand

Global forecasted manufacturing capacity to reach 54 GW by 2027 and up to ~2x of demand in 2030

EH2 already has 5 GW of orders lined up for their 1.3 GW factory, so EH2 feels confident about its ability to keep its current facility busy. The company is also contemplating building a second factory.

Jason Mortimer, senior vice president of global sales for EH2 said,

“Green hydrogen is not a thing yet. We are making it a thing, and there’s all kinds of challenges associated with that, but it is happening.”

He also said he sees the tech like solar was prior, growing and figuring things out, both in the buyer and manufacturing side – so give it time.


SolarCycle aiming for 6 GW/year of recycled solar glass in Q Cell deal

US$344 million in investment, the facility will be capable of producing enough solar glass for between 5GW and 6GW of PV capacity annually.

Construction is scheduled to begin in 2024, with operations in 2026.

I don’t think the USA is producing 5-6 GW of solar waste per year. Wonder if this company will need to import to meet goals.


Aiko hits 25.15% solar panel efficiency

Aiko Solar has reported achieving 25.15% conversion efficiency for its ABC modules.

Georgia considering Community Solar, Utility against it

House Bill 1152, customers could subscribe with community solar providers for projects producing no more than six megawatts of power. Because the measure calls for the amount of credit on bills community solar customers would receive to be determined by the state Public Service Commission (PSC), it would be limited to Georgia Power customers since the state’s other utilities are not regulated by the PSC.

representatives of Georgia Power, who spoke out against the bill, said there is no energy supply shortage in Georgia that needs to be addressed.

The subcommittee was only scheduled to hold a hearing on the legislation Monday and took no action on the bill.


For now, logically, solar panels as cheap as they’re gonna get

Our fundamental cost modelling allows us to look at where ‘sustainable pricing’ can go. In the near term it looks like spot prices have largely stabilised. Potential oversupply could push prices down even further, but ‘sustainable’ cost reductions in the medium term look fairly difficult,” said Barrows.

The analyst noted currently “materials and consumables” make up 80% of solar panel production costs, thus there is little room.

Solar panels die 6.6% to 10% faster in a hotter Australia

Higher heat means more solar panel degradation. Australian researchers project solar panel breakdown rates by component due to increased temperatures.

We estimate that the weighted average degradation rate will increase up to 0.1%/year by 2059. On assessing the impacts of module degradation on future PV power generation and levelized cost of energy, we project up to 8.5% increase in power loss that leads to ~10% rise in future energy price…standard degradation rates vary from 0.26%/year to 2.3%/year depending on the dominant degradation mechanism and module type…ultraviolet (UV) radiation, temperature and humidity as the main climate stresses that lead to different degradation mechanisms by themselves or in synergy…Hot spots (33%) are the most common mode of degradation in monocrystalline-silicon (mono-Si) modules. The other common modes of degradation in mono-Si modules are ribbon discoloration (20%), glass breakage (12%), encapsulant discoloration (10%), cell breakage (9%) and PID (8%).

The occurrence probability of solar panel degradation modes depending on the climate type.
The occurrence probability of solar panel degradation modes depending on the climate type.


Our results show an increase in LCOE throughout the country under both future scenarios. We observe maximum changes in LCOE in the north-western part of the country up to 6.5% under RCP2.6 (Figure 3c) and up to 10% under RCP8.5 (Figure 3d). This means that energy will cost an additional 8 cents/kWh in those regions. The cost of energy in Eastern Australia is projected to increase up to 3 cents/kWh (up to 5%) in the future from the present rate (~70 cents/kWh). As expected, Central Australia is projected to undergo the least changes in future LCOE (up to 2%). We project that by the end of the century, the energy cost shall increase up to 8% under the RCP2.6 scenario (Figure S3). Under RCP8.5, we predict a 2% increase in LCOE near the central regions of Australia, up to 8% in the east and south and up to 15% in the north due to an increase in future power loss (Figure S3).

Highway solar “slam dunk” for Rhode Island

Rhode Island commission recommends 15 sites along the highway to install solar power. An analysis suggests it’s enough for 100,000 kW – average house needs 10 kW.

“It’s a slam dunk,” Robert Rocchio, a chief engineer at RIDOT, told commission members last month. “It’s a way of extracting value from land that otherwise has no utility.”

State and federal road groups will setup standard construction requirements, after which contractor bids will be requested.


53 GW new solar, 14.3 GW new batteries for USA in 2024

US projecting 53 GW of new solar, and over 81% of new power grid capacity from solar+batteries.

Utility scale solar is projected to deploy 45 GW of module capacity, while distributed solar is expected to deploy at least 8 GW of capacity. Energy storage is expected to deploy 14.3 GW of power output capacity – which is almost equal to all the batteries (15.5 GW) installed in total in the country in all years prior.

War driving Ukrainian solar

‘Galushchenko said last year Ukraine constructed around 200 megawatts of wind and around 150 megawatts of solar power capacity.

Even if “it’s not a big amount, I can say that this is due to the war,” he said.’

Russian forces have destroyed 11 coalmines, which they did to weaken Kyiv’s capacity to produce energy, Ukraine has eight power plants in non-occupied territory that can run on coal or natural gas, of which three have been knocked out of action.

(China’s) rapid growth of renewables, supported by rising nuclear generation, is set to displace global coal-fired generation, which is forecast to fall by an average of 1.7% annually through 2026. This follows a 1.6% increase in coal-fired output in 2023 amid droughts in India and China that reduced hydropower output and increased coal-fired generation, more than offsetting strong declines in coal-fired generation in the United States and the European Union.

While it is true that China is building more coal generation capacity, they’re using it less. Globally, this can also be seen in that all of the world’s electricity demand growth is thought to be met by new clean (nuclear, solar, wind, hydro) electricity generation. This is also occurring while global electricity demand is set to grow by an average 3.4% annually through 2026.

The report, from the IEA, also says that emissions from electricity – on a global level – are starting to fall. This happens as renewables are expanding their presence from 30% of all electricity, to 37% – with the IEA saying this growth is being largely supported by “ever cheaper solar PV”.

Cool solar pictures with Patagonia gear by Jesse Burke

Jesse Burke, a Rhode Island based photographer, reached out to us via LinkedIn to advertise his services – specifically noting that he’d done some work with Patagonia at a solar project. Here are some of those images from his website.

I really like the image with the icicles coming from the solar module.

Bird droppings accounted for about 46.42% to 89.18% of efficiency loss [in solar panels].

The biggest problem? Bird droppings.

Loose wiring

The natural movement of birds and animals can loosen panel wiring. When connections are compromised, it can have a negative effect on an entire system and efficiency can suffer. Squirrels also like to gnaw on the wires, for some reason known only to themselves.

Birds and other animals sometimes decide to build nests or burrows among solar panels. The new residents then constantly move around the system, increasing the risk of poor connections.


1.7 GW of solar, and 1.3 GW of storage moving along, BLM also updates solar plan

Department of the Interior announced updated roadmap for solar energy development across the West…announced next steps on projects in Arizona, California and Nevada – ~1,700 MW solar & 1,300 MW of storage.

During the Biden-Harris administration, the BLM has approved 47 clean energy projects and permitted 11,236 megawatts of wind, solar and geothermal energy on public lands.

BLM & NREL forecasted national clean energy needs and determined ~700,000 acres of public lands would be needed…BLM’s preferred alternative in the updated Western Solar Plan would provide approximately 22 million acres of land open for solar application, giving maximum flexibility to reach the nation’s clean energy goals.

The analysis announced today evaluates six alternatives, each proposing to make different amounts of public land available to solar development applications under different criteria such as proximity to transmission infrastructure, designated critical habitat, or other important ecological and cultural resources.


Fire at South Australian solar farm

Inverter burst into flames at the 30 MW Mannum Stage 2 solar farm, which is being developed near the town of Mannum, South Australia. A worker is now being treated in the hospital for burns. Estimated $250,000 damage bill. The CFS said 10 firefighters responded on Tuesday morning after an emergency call about an inverter in “bursting into flames” at the solar farm site.

“CFS crews managed to keep the fire contained to the shipping container and stop it spreading to nearby solar panels,” CFS said in a statement.


6 gigawatts of US agrivoltaics

There is now a 1.3 GW agrivoltaic array in northern Indiana, in New York state, which will deliver its first specialty crop array in 2024 and the Shines program, in Illinois, has more than 50 projects which are choosing to include agricultural production within half of their arrays. The National Renewable Energy Laboratory (NREL) says that there is nearly 6 GW of agrivoltaic generation capacity operating in the United States, ranging from solar panels on grazing pasture to crop fields.


Vertical solar at higher latitudes generate more

Unsurprisingly the yield curve for the solar fence was different to ground-mount solar, with a dip in the middle of the day, but on an annual basis, overall yields were slightly higher for the solar fence than for the conventional system. “We’re seeing a 10% total uplift in yield in London and a 3% increase in Sydney,” Gridcog said, noting that while the physical performance more or less aligned with what was expected, the commercial story provided some interesting results.

“On an annual basis the advantage of the solar fence is even more obvious,” Gridcog said. “The increase in revenue is significantly higher than the underlying increase in yield; in the case of Sydney a 3% increase in yield has translated into a 30% increase in revenue.”


Solar supply chain pricing stabilizing

FOB China prices of Mono PERC M10 wafers trended flat on-week at $0.241 per piece (pc), while Mono PERC G12 wafer prices remained at $0.356/pc. According to the projection of the Silicon Industry of China Nonferrous Metals Industry Association, China’s overall wafer production output in January might range from 54 GW to 56 GW, indicating a decline of 7.92% month over month. According to a market expert, wafer manufacturers still try their best to maintain operating rates at a particular level despite the continuous wafer overcapacity. At present, polysilicon prices make up about half of wafer production costs.


Rooftop solar has shorter energy and CO2 payback than utility scale

‘rooftop solar systems require 21% to 54% less input energy, make 18% to 59% less carbon dioxide equivalent of greenhouse gas emissions, and consume a reduced quantity of water ranging from 1% to 12% per kilowatt-peak. Researchers calculated energy payback time of rooftop solar systems is approximately 51% to 57% lower than that of ground-mounted solar systems across all locations, with the main reason being that rooftop systems don’t required the racking or trackers used in large-scale projects. Plus they are usually closer to transmission lines, whereas many utility-scale installations need lines added or they must account for transmission losses if running a long distance. The researchers determined that the carbon dioxide payback time was 378% to 428% longer for ground mount large-scale solar installations, compared to rooftop solar for the same modules.

NREL sees gas capacity going up, even with decarbonization

In a “mid-case” scenario tied to existing policies, U.S. gas-fired capacity increases by 200 GW through 2050, National Renewable Energy Laboratory researchers said in a report released Tuesday. And, even when cutting carbon emissions by 95%, gas-fired capacity would grow by 130 GW by mid-century, according to the modeling. “We will continue to use fossil fuels during times of critical demand to provide grid resilience and reliability,” NREL said.

The mid-case modeling shows U.S. solar capacity soaring to 1,090 GW and wind capacity jumping to 770 GW by 2050, or about tens times and five times more than existing capacity, respectively.

Cheap modules messing up solar recycling

Prices of new solar modules continue to decline; they’re forecast to fall to as little as 10 cents per watt by the end of 2024. Squeezing the secondary market. With prices for new modules so low, the demand for used panels has slackened. In fact, We Recycle Solar, which has a multi-pronged business that includes solar decommissioning and panel recycling, estimates that the average cost just to truck and handle panels being decommissioned is between five and seven cents per watt.


Solar and wind to lead U.S. power grid next two years

As a result of new solar projects coming on line this year, we forecast that U.S. solar power generation will grow 75% from 163 billion kilowatthours (kWh) in 2023 to 286 billion kWh in 2025. We expect that wind power generation will grow 11% from 430 billion kWh in 2023 to 476 billion kWh in 2025. In 2023, the U.S. electric power sector produced 4,017 billion kilowatthours (kWh) of electric power. Renewable sources—wind, solar, hydro, biomass, and geothermal—accounted for 22% of generation, or 874 billion kWh, last year.

Planned solar projects increase solar capacity operated by the electric power sector 38% from 95 gigawatts (GW) at the end of 2023 to 131 GW by the end of 2024. We expect wind capacity to stay relatively flat at 156 GW by the end of 2024, compared with 149 GW in December 2023.


Wind turbine collapses in Colorado

Wind turbine at a northern Colorado wind farm folded in half and caught fire Thursday morning.

The incident was reported at 8 a.m. No injuries were reported. Oil and grease from the generator caught fire after the tower’s collapse. The fallen turbine is one of 19 units in the Spring Canyon II project that came online in 2014. Invenergy employees ensured the fire department did not spray water on the fire until the generator had been grounded or the turbine disconnected from 480,000-volt power grid. His volunteer firefighters know not to do that, thanks in part to annual training sessions with Invenergy workers.


Perovskite company raises $6 million

Tandem PV has raised an additional $6 million, bringing its total to $27 million in venture capital and government support. The company will use the funds to advance research and development and plans to build its first manufacturing facility.

The company is producing tandem perovskite panels with 26% efficiency, which is roughly 25% more powerful than the average silicon solar panel. Tandem PV has demonstrated the equivalent of decades of projected durability in the lab. The company plans to obtain independent industry-standard validation of efficiency and durability, expected to rise further, during 2024.


Wind made steel going into wind turbine

The tower sections at Baltic Power will be made of ArcelorMittal’s XCarb recycled and renewably produced heavy plate steel.

The company will produce steel slabs at its steel mill Industeel Charleroi in Belgium, using 100 per cent steel scrap which is melted in an electric arc furnace fully powered by wind energy. The steel slabs will then be transformed into heavy plates used to fabricate wind turbine towers at ArcelorMittal’s heavy plate mill in Gijon, Spain.

Using this low-emission steel in the top two sections of an offshore turbine tower would translate to approximately 25 per cent emission reduction, compared to a tower made from steel made via a conventional steelmaking route. For an entire onshore tower, the CO2 reduction is at least 52 per cent, according to Vestas.

The 1,140 MW Baltic Power offshore wind farm will be built approximately 22 kilometres off the Polish coast near Plaża Wydmy Lubiatowskie. Delivery of the Vestas wind turbines is expected to begin in the first quarter of 2025, with commissioning expected in 2026.


Battery cells falling below $56/kWh

Several sources indicate the price of EV #LFP battery cells in China is falling below US$56/kWh; Leapmotor said the price can be further squeezed to US$45/kWh. Both CATL and BYD have put battery pricing reduction strategies in place for 2024.


20% of new car sales this year will be electric

We expect 16.7 million passenger EVs to be sold and another million commercial EVs. Number of EVs on the road should reach 57 million by the end of the year. That is over 4% of the fleet.

We expect a record 1.6 million public EV charging connectors to be added in 2024, up from 1.2 million added in 2023.


Texas setting solar record during winter

‘There’s a new solar record in Texas! Fitting it’s happening on this ultra cold, high demand day. We’re over 14,000 megawatts which is 3x the amount we had three years ago!’


TOPCon solar module production costs 16¢/W in China – EU, US, and India 18-75% higher

China can now produce tunnel oxide passivated contact (TOPCon) PV modules for between $0.160/W and $0.189/W. Costs in Europe, India and the United States, by contrast, could be as low as $0.243/W, $0.281/W, and $0.195/W, respectively.

Assumptions were based on the idea of module manufacturing at a 10 GW integrated PV factory.

Chinese manufacturers could currently produce heterojunction panels for between $0.173/W to $0.198/W. The price range for potential European module makers is indicated at between $0.250/W and $0.305/W. Indian and US producers, meanwhile, should achieve prices of $0.209/W and $0.290/W, respectively.


Tesla Solar Roof pricing – make sure to account for the new roof

‘A Solar Roof without batteries in Illinois had an estimated cost of $5.72 to $6.54 per watt depending on roof complexity. Another estimate from Texas ranged from $6.05 to $6.77 per watt.’

‘Roof size does significantly affect the overall cost of a system. A small roof (1,594 square feet) in Illinois could cost around $54,000 to $58,148 after the federal tax credit, Tesla estimates. That’s $3.78 to $4.05 per watt, much closer to the cost of solar panels, though still more expensive. (Tesla solar panels there would cost $2.54 per watt after the federal tax credit.)’


GM battery manufacturing town may ban all power plants

‘Lordstown Village Council is holding a public hearing at 5:30 p.m. to discuss legislation that includes prohibiting of new permits for wind energy systems, solar energy systems, and any “major electric facilities.”

Large wind and solar farms have been banned in all 18 townships of Columbiana County as of October.’


Tesla Powerwalls & Inverters failing

From analyst Roth MKM…

“he is seeing substantial failure rates…he said the TSLA inverter and the Powerwall+ are now both failing at a 10% rate vs. 4% for inverter only in Q4’23 and 10% for the Powerwall+. Despite that…he still plans on switching 60% of his 2024 resi inverter business to Tesla.”


Solid state battery research – dendrite, and silicon density – fast charge and long life hopes

Li and his team stop dendrites from forming by using micron-sized silicon particles in the anode to constrict the lithiation reaction and facilitate homogeneous plating of a thick layer of lithium metal…”In our design, lithium metal gets wrapped around the silicon particle, like a hard chocolate shell around a hazelnut core in a chocolate truffle”…These coated particles create a homogenous surface across which the current density is evenly distributed, preventing the growth of dendrites. And, because plating and stripping can happen quickly on an even surface, the battery can recharge in only about 10 minutes…retained 80% of its capacity after 6,000 cycles.


Energy storage developer raises $225 million

NineDot said yesterday (10 January) that it has secured US$225 million in equity capital commitments from Manulife Investment Management, which led the round with a US$135 million commitment, and another global investment firm, Carlyle.

The money brings NineDot’s investment raised to date to more than US$400 million and will be used to advance its NYC pipeline. It could also go towards expanding the company’s reach into other geographies or making acquisitions.

NineDot is thought to be developing around 30 to 40 separate lithium-ion BESS sites around the city, each planned as 5MW output with 4-hour duration (20MWh).


Plastic based flow battery that emulates human body

“CMBlu fills its storage tanks with a solid polymer that holds a charge, and then transfers it to and from the liquid electrolyte, which is pumped into an electrode stack for charging and discharging cycles. Kaun likened that system to how the human body stores energy in fat, and then transfers that energy to blood sugar when it needs to be delivered to cells.”

‘”What we have here at CMBlu is a rechargeable polymer, a rechargeable plastic. We can make the plastic [and] recycle the plastic.”




53.5 GW of solar in 2024 – 65 in 2025

That’s going to be nearly $100 billion in solar installed this year, and more than $120 billion in 2025. 80% of this capacity will be utility scale facilities.

The new capacity turn on in 2024 will offset roughly 1.3% of all electricity demand in 2025, with all solar meeting 8.3% of national electricity demand.

The 65 GW of capacity could cover 1.6% of all electricity demand, pushing solar to 9.9% of 2025 electricity. At this point wind and solar will be nearing a quarter of all electricity.


America’s kgreenhouse gas emissions down 1.9% in 2023, 0.5% in 2024, and 2.5% in 2025

The power industry drove emission declines, while both transportation and industry increase in 2023. Natural gas generation grew more than twice as fast as renewable generation did, year-on-year.


The EIA sees that in 2024 and 2025, power emissions may only fall by half a percent, increasing to 2.5% in 2025.

Sub zero heat pumps

‘The conditions for the prototypes are that they have to deliver 100 per cent heating capacity without the use of extra heating sources and high efficiencies at 5° fahrenheit (-15° celsius)…Bosch, Daikin, Midea, and Johnson Controls join Lennox International, Carrier, Trane Technologies, and Rheem in the next phase of the challenge…Bosch says it can keep operating in temperatures down to -15°C and still function at -25°C’


Hertz selling used Teslas

The card rental company is selling its used EVs as they reach the end of their second year of use, which I’d the company’s standard policy. Model 3 & Y units are seemingly available.

Pricing starts at just over $20,000 with the cars eligible for a $4,000 used EV tax credit.


The price of home charging an electric vehicle in the U.S., on average, is equivalent to $1.41 per gallon.

Map shows how cheap gasoline would have to be in order to be on par with the cost of at-home EV charging. In most parts of the country, charging an EV is equivalent to a gasoline price of $1 to $2 per gallon.

Massachusetts is $2.32/gallon to break even with its more expensive electricity – while Hawaii is the highest at $3.59/gallon. Louisiana & Washington have the cheapest electricity driving the comparable cost to $0.98/gallon.

These comparisons were made by calculating a “gallon-equivalent” for electric vehicles. This number is based on three factors: The average kilowatt hour per mile to drive an EV, the average miles per gallon for a comparable gasoline-powered vehicle, and the price of electricity. Multiplying these three numbers together yields the cost of driving an EV the same distance as a traditional car would travel on one gallon of gasoline.


Solar farms offer food availability and nesting sites for birds, contributing to avian diversity

‘According to the research group, bird species richness, diversity, and invertebrate-eater species richness and abundance were higher in the solar parks than in the control plots. Among the reasons provided by the research group is the food availability for insectivorous birds, as the PV panels attract various species of water-seeking aquatic insects.’

Overall, the academic group spotted 353 individuals of 41 species in the solar parks and 271 individuals of 40 species in the control plots. Black redstart, European stonechat, white wagtail, and Eurasian tree sparrow were identified as species most strongly associated with solar parks.’


Rough black silicon optimal for solar cells

‘Black silicon is made when the surface of regular silicon is etched to produce tiny nanoscale pits on the surface. These pits change the color of the silicon from gray to black and, critically, trap more light, an essential feature of efficient solar cells…As flourine gas etches away at the silicon unevenly, pits are created on the surface of the silicon. The rougher the surface, the more light it can absorb, making rough black silicon ideal for solar cells’


China’s rooftops fed its solar boom, but challenges arise

‘Three cities and counties announced in recent days that local power infrastructure can’t currently absorb more distributed solar generation…adds to about 150 locations nationwide that have also reached their limit’

China’s rooftops have more solar than entire countries.


Government expect batteries deployed in the US to double in 2024

U.S. battery storage capacity could increase by 89% by the end of 2024 if developers bring all of the energy storage systems they have planned…Developers currently plan to expand U.S. battery capacity to more than 30 gigawatts (GW) by the end of 2024, a capacity that would exceed those of petroleum liquids, geothermal, wood and wood waste, or landfill gas…California has the most installed battery storage capacity of any state, with 7.3 GW, followed by Texas with 3.2 GW.

Planned and currently operational U.S. utility-scale battery capacity totaled around 16 GW at the end of 2023. Developers plan to add another 15 GW in 2024 and around 9 GW in 2025.


Maine getting first large utility scale battery

‘Plus Power plans to start work this spring on Maine’s largest battery storage project at the Gorham Industrial Park. Cross Town Energy Storage will be rated at 175 megawatts/350 megawatt hours and provide the region’s grid operators with instant power when needed…The $100 million-plus project will feature 156 tractor-trailer-like containers spread across five acres in the Gorham Industrial Park, stuffed with lithium iron phosphate batteries…Plus Power is using battery systems supplied by Sungrow, a Chinese global clean energy company. There will be 3,072 battery cells in each 30-foot long container…Maine currently has 63 megawatts of grid-connected energy storage at six locations.


Burnt DC combiner box connections on a solar plant

In a solid argument for keeping up with your operations and maintenance work, here’s a site we visited today.

DC combiner boxes filled with leaves, along with loose connections due to years of small shifts, led to connections being burnt.

The solar panels are wired in a series that end at the combiner box, which connects multiple strings of solar panels in parallel. The combined wire of the in panels, now much larger, then goes to the inverters where it is converted from direct current into alternating current.

US Government: Significant solar increase over next two years

The U.S. Energy Information Administration (EIA) expects solar electric generation will account for 7% of total U.S. electricity generation in 2025, up from 4% in 2023, according to its January Short-Term Energy Outlook (STEO). Developers have reported that almost 80 gigawatts of solar power will come online over the next two years, increasing U.S. solar generating capacity by 84% and making solar the leading source of growth in U.S. electricity generation through 2025.

“We are experiencing a significant shift in U.S. electric generation, as solar generation grows rapidly, taking market share from coal and tempering the growth in natural gas usage,” said EIA Administrator Joe DeCarolis. “Coal and natural gas remain important to the U.S. electric grid, even as variable renewable resources such as solar and wind grow.”


World’s largest solar, wind, and energy storage power plant

‘$7.7 Billion Renewables Mega-Project… 6 gigawatts of wind and solar capacity and 3.4 gigawatt-hours of energy storage…connected to the grid by the end of 2025…power to Beijing and its surrounding areas via the Datong-Tianjin ultra-high voltage power line’


Just unionized solar installers & technicians furloughed for a year

“EmPower Solar, in Bethpage, NY…unionized over concerns about poor working conditions and issues they faced on the job…on 22 December, workers at Empower voted to join UAW Local 259…on 30 December, EmPower furloughed 21 workers until 2025…company says “solely due to a slowdown in business”…UAW Local 259 claimed this amounted to a “union busting” tactic”


The UAW railed against EmPower on Saturday.


Renewables, batteries, and EVs as China’s economic-security-social strategy

“export value of electric cars, batteries and solar panels grew 42% on-year in the first three quarters of 2023…Domestic sales of those products are even larger than exports, fueled by subsidies for solar installation and EV purchases”

“Part of that focus is what they call the “new three” growth drivers of electric vehicles, batteries and renewable energy, aiding the world’s de-carbonization push and fueling demand for commodities such as copper and lithium.”


“manufacturing focus is driven by a mix of economic, security and social stability objectives”

“every 100 new manufacturing jobs are associated with 27 new non-manufacturing jobs; by contrast, every 100 new service jobs are associated with only 3 additional manufacturing jobs”

Lithium energy storage up 100%+ in 2022 & 2023 – 2024 outlook

‘It is anticipated that the installation of large-scale energy storage could reach 53GW/128.6GWh globally in 2024…United States could reach 11.6GW/38.2GWh…China – 24.8GW/55GWh’


‘Total combined output of power and energy storage batteries in China reached 698.7GWh, marking a 41.6% year-on-year increase. In December, the average price of Chinese energy storage batteries dropped to 0.45 yuan/Wh ($0.063/Wh), experiencing a monthly decline of around 4%.’

Electric buses at Steamboat Authority in Massachusetts

Was riding the ferry to Martha’s Vineyard to visit the lady’s family, and mentioned how quiet and electric sounding the buses sounded going from the Palmer Parking lot to the boats. On the way back from the island, saw that the units were in fact BYD, chosen in 2021 and deployed in September of this year!

‘40.2-foot K9M bus has a seating capacity of up to 37 passengers…top speed 65 MPH…range 157 miles…charging 2 to 2.5 hours’

$0 electricity bill in June

Visited a commercial customer of our on Wednesday to work through some operations and maintenance work. Got a chance to view the electricity bill that one of the five solar power installations we’ve done for them looks like.

It looks great for a behind the meter project!

Same has some serious cool/old switchgear that we’ve integrated Solyndra and other solar hardware into it. Plus really nice to walk into his office place and see the solar power systems we’ve built for him (and whose key information we supplied in both hard and soft copies) on the shelves.


Solar polysilicon pricing down, much like in 2011

If we’re in for a batch of history repeating itself, then we’ve got a decade of cheap solar polysilicon coming for us. The first image below is from Bernreuter Research and it shows the pattern of polysilicon prices movements in 2011 vs 2023. The second image shows polysilicon pricing from 2004, to 2011, and then from that price drop through 2020+.

One reason we *might* have the same ongoing pricing trends (i.e. cheap poly) is that China is massively expanding capacity. While demand is growing, it seems capacity is leading.

BYD world’s #1 EV sales company Q4’23, Tesla #1 revenue & profits

For Q4’23, BYD passed Tesla for total electric vehicles sold – 526,409 to 484,507. This is credited to BYD deeper roster of models offered at lower price points.

Tesla does lead in total revenue and profits (much like Apple leads Android products in profits while being outsold heavily).

‘BYD doesn’t sell in the US, where its vehicles would face a 27.5% import tariff.’


Retrofitting solar power plants with energy storage

NextEra has retrofitted the 100 MWac/135 MWdc Saint Solar farm with a 100 MW/400 MWh battery energy storage system in Coolidge, Pinal County, Arizona. NextEra has regularly said they see retrofitting their existing fleet of solar assets with energy storage as one of their greatest revenue generating opportunities. It’s been suggested that it’s going to be challenging to retrofit existing solar power plants with energy storage for a few reasons, however, there are a few companies that think long and far enough – as well have the skills and funding to prepare for these current times. There will be ample opportunity to build out our near 100 GW of existing utility scale solar power with energy storage.

Massachusetts wind farm to start delivering within days

Vineyard Wind will begin to deliver “65 megawatts worth” of wind turbines, via five units, to the power grid before the end of 2023, per the Cape Cod Times. The value will increase toward the facilities full 806-megawatt capacity through 2024, when the plant is expected to be fully operational. We think the 65 MW value is actually wrong, as the article states five units will come online – at 13 MW each. The site’s units were changed to 14 MW units recently, suggesting 70 MW of capacity will be deployed and start delivering.

It’ll be quite interesting to see how the plant works in winter times where capacity factors can be extremely high off of the coast, especially high with these 107 meter long turbine blades.

SunZia Transmission is a 550-mile ±525 kV HVDC transmission line between central New Mexico and south-central Arizona with the capacity to deliver clean power generated by Pattern Energy’s 3,515 MW SunZia Wind facility. The power generation facility is being constructed across Torrance, Lincoln, and San Miguel Counties in New Mexico. The deal includes an integrated construction loan & letter of credit facility, two separate term facilities, an operating phase letter of credit facility, an innovative tax equity term loan facility and a holding company loan facility.

Construction is underway on the SunZia Transmission and Wind project in New Mexico

A $100 trillion opportunity

Wrote a story for pv magazine USA. It’s about the future, and potential, and widening the “Solar Overton Window”. Building out the world’s solar capacity – along with energy storage – will create a $100 trillion opportunity if some of the more aggressive ideas currently spoken of are fulfilled. Jigar Shah says,  “This is the largest wealth creation opportunity of our lifetimes. There will be nothing else that will produce more wealth, more jobs, more work.”

Stay persistent, stay focused, be aggressive, go big over time – that’s our goal.
