Tesla and Panasonic to kill cobalt curse

Panasonic announced an aim to produce batteries for Tesla without using cobalt, much of which is sourced from the unstable and conflict-ridden Congo. June 5, 2018John WeaverOnly a few years ago, there were popular predictions that we would run out of oil, whereas today it, appears more likely that oil markets will suffer from peak demand, not supply. Similar arguments about resource scarcity have surfaced widely in anti-renewable propaganda, with concerns expressed about rare earths, lithium and other materials as easily debunked reasons why solar, wind and energy storage cannot scale.Some of these concerns could have been valid, were it…

Golden solar module released by Jinko – for the lifestyle customer

"Studies have shown that residential PV users, on average, are financially well off and are early adopters of new lifestyles and products. These end-users have higher requirements for product personalization and quality. Combining a high efficiency of 19.37% and elegantly luxurious design, JinkoSolar golden frame module is the ideal solution for the residential PV market." Solar panel bling baby! (more…)

LG Neon Bifacial spec page – 500W on a white membrane roof!

This spec page has been out for a bit, but this is the first I've seen it. This seems a utility scale panel versus standard commercial - note the 1500V notation, but the bifacial information is probably applicable to a residential or any other version panel. Notice that, in some wonderful perfect world, you can get a 25.4% output boost. I really want to get a database of roofing companies that have installed white roofs, so I can call on the customers.

Meyer Burger – 410 watt, 72-cell module using 23.4% efficient heterojunction cells

Snuck down at the bottom of a Panasonic press release, Meyer Burger announced a a 410W solar panel with 23.4% efficient solar heterojunction solar cells. This panel reminds me of what was announced with SolarTech Universal late in 2017. That panel had a champion solar cell hit 24.02% - the overall panel efficiency was at 20.5%. Same product line. An LG 410W, 72 cell solar module has an efficiency of 19.8%. The broader article... (more…)

Residential PERC solar panel list as part of PERC technology roadmap

Last night I read the @TaiyangNews - 'PERC Solar Cell Technology 2018' presentation. Part of the document included a great list of the leading PERC solar panels. The broader document paints a wonderful picture of the different potential technology pathways of PERC solar cells. Seems like PERC based solar cells will hit almost 50% of global sales this year, and it might hold onto its position of leading technology from the upcoming, higher efficiency heterojunction because it has a few more pathways to squeeze more efficiency from the solar cells at such amazing pricing. PERC cells have peaked at 23.9% efficiency…

New DSM backsheets are conductive, can increase solar module output by 3%

A 3% increase isn't trivial - celebrate our incremental innovation. If a solar panel is at 16-20% already - it'll add 0.5-0.6% more in efficiency. Over 30 years - that adds up. This is the technology that has helped SunPower stay at the lead of efficiency, and - in general - mirrors the trend of limiting busbars and other things blocking sunlight on the front of the panel. Expect this technology to dominate in the long game. (more…)

Daqo solar polysilicon gets government approval and cheaper power for production expansion

Cheaper polysilicon production means cheaper solar panels. Making silicon pure enough for the higher efficiency solar panels is the main driver for the price difference between poly (standard) and mono (high)  solar panels. China is strategically locating high electricity use industry close to cheap electricity. Right now, it is we - the solar industry and the planet - benefitting from this cheaper electricity. Monocrystalline panels will probably eventually take over from poly. (more…)
