Quick answer: In 2026, a commercial rooftop in Massachusetts typically earns about $0.45–$0.70 per square foot of usable roof area per year from a solar lease, and a Rhode Island rooftop about $0.50–$0.80. For a 25,000-square-foot roof, that is roughly $11,000–$20,000 a year, usually under a 20-year lease, with no installation cost to the building owner.
Key takeaways
- Massachusetts: about $0.45–$0.70 per square foot per year; typical $0.58.
- Rhode Island: about $0.50–$0.80 per square foot per year; typical $0.65.
- Most leases run about 20 years, often with annual rent increases.
- An aging flat roof can often be replaced as part of the solar deal.
- Solar projects that start construction now must be placed in service by December 31, 2027 to receive the federal tax credit.
This guide shows what to expect by roof size in each state, what moves the number up or down, and how to get an exact quote for your building.
How much does a solar roof lease pay in Massachusetts?
A Massachusetts commercial roof typically earns $0.45–$0.70 per square foot per year, with $0.58 a common midpoint.
Figures are estimated annual lease payments for a standard-to-strong commercial rooftop, based on the usable square footage that can actually be built on. Your exact number depends on your building, so treat these as a starting range.
Massachusetts: estimated annual solar lease payout by roof size
| Usable roof area (SF) | Low ($0.45/SF per year) | Typical ($0.58/SF per year) | High ($0.70/SF per year) |
|---|---|---|---|
| 10,000 | $4,500 | $5,800 | $7,000 |
| 15,000 | $6,750 | $8,700 | $10,500 |
| 25,000 | $11,250 | $14,500 | $17,500 |
| 40,000 | $18,000 | $23,200 | $28,000 |
| 50,000 | $22,500 | $29,000 | $35,000 |
| 75,000 | $33,750 | $43,500 | $52,500 |
| 100,000 | $45,000 | $58,000 | $70,000 |
Market pricing varies widely. Competing bids for the same roof can differ by nearly 3x, which is why getting a project-specific quote matters. In Massachusetts, Lumen Energy’s Lumen Solar Index (Q2 2026) put the average at about $0.58 per square foot per year, with a range of about $0.36–$0.74 across live bids and executed leases.
How much does a solar roof lease pay in Rhode Island?
A Rhode Island commercial roof typically earns $0.50–$0.80 per square foot per year, with $0.65 a common midpoint.
Rhode Island: estimated annual solar lease payout by roof size
| Usable roof area (SF) | Low ($0.50/SF per year) | Typical ($0.65/SF per year) | High ($0.80/SF per year) |
|---|---|---|---|
| 10,000 | $5,000 | $6,500 | $8,000 |
| 15,000 | $7,500 | $9,750 | $12,000 |
| 25,000 | $12,500 | $16,250 | $20,000 |
| 40,000 | $20,000 | $26,000 | $32,000 |
| 50,000 | $25,000 | $32,500 | $40,000 |
| 75,000 | $37,500 | $48,750 | $60,000 |
| 100,000 | $50,000 | $65,000 | $80,000 |
Example: 25,000 SF in Rhode Island. At the typical rate of $0.65/SF, you would receive about $16,250 in year one and about $325,000 over a 20-year lease, before any annual rent increase. Your lease is with the solar project owner, which sells the power under a long-term Renewable Energy Growth contract with Rhode Island Energy. That utility contract is what makes the payments dependable. See our rooftop commercial solar installation in Bristol, Rhode Island.
Why are commercial roofs in Massachusetts and Rhode Island in demand?
Both states reward the solar production from commercial rooftops, which is what lets developers pay property owners well.
Massachusetts. The SMART 3.0 program pays per kWh for 20 years. Program Year 2026 base rates range from $0.2807 per kWh for systems above 25 kW up to 250 kW AC down to $0.179 per kWh for systems above 1 MW up to 5 MW AC, before adders. Rooftop systems earn an added $0.03 per kWh for being building-mounted, or $0.04 per kWh at 900 kW AC and above. Applications at 2026 rates are accepted through December 31, 2026. The state’s draft 2027 report would cut capped capacity to 300 MW from 600 MW, lower base rates for systems up to 500 kW and raise them for larger systems, so the better year to apply depends on your roof.
Rhode Island. The Renewable Energy Growth program offers fixed per-kWh payments for solar output under long-term contracts with Rhode Island Energy. For upcoming program years, state regulators are developing separate ceiling prices for projects that will and will not qualify for the federal tax credit.
These incentives support the project, but they do not translate directly into your lease rate. Your payment depends on construction cost, interconnection and financing rates, which is why each roof is priced on its own numbers.
Can a solar lease pay for a new commercial roof?
Often, yes.
If your commercial roof is leaking, aging or due for replacement, you may not need to pay for it yourself. A solar lease can turn that expense into a benefit: instead of paying for a new roof out of pocket, the replacement can often be funded as part of the deal.
The logic is simple. A solar array needs a sound roof to sit on for 20 years or more, so the developer has a strong reason to make sure the roof is in good shape before the panels go up. Depending on your building and roof condition, that can work in a few ways:
- New roof at no upfront cost. The roof is replaced or restored before installation, and the cost is built into the lease economics so you do not write a check.
- Rent credit. Your lease payments offset the cost of the work over time.
- Repair and warranty coordination. We coordinate the roofing work with the closely held construction partners we are closely integrated with, so the new roof warranty stays intact.
This matters because commercial roof replacement is one of the largest capital expenses a building owner faces. A flat roof such as TPO, EPDM, modified bitumen or built-up roofing can cost tens of thousands of dollars to replace. Pairing the replacement with solar lets you retire that cost and start earning lease income from the same roof.
A roof is a good candidate when it has structural capacity, enough open area and a service life that can be extended with a replacement. Warehouses, manufacturing plants, distribution centers and schools across Massachusetts and Rhode Island are common fits. We evaluate each roof individually, so whether the full cost is covered depends on its size, condition and the project economics. The fastest way to find out is a free roof and solar assessment.
What affects how much your roof earns?
- Size and layout. Large, open, unobstructed flat roofs earn the most. HVAC units, skylights and setbacks reduce usable area.
- Roof condition. A roof that needs replacement may be costed into the deal, as described above.
- Location and utility territory. Interconnection availability and cost vary by area and have the largest effect on what a project can afford to pay. In Massachusetts that means Eversource, National Grid or Unitil territory; in Rhode Island, Rhode Island Energy.
- Electrical capacity. Proximity and capacity of the nearest grid connection can raise or lower your rate.
- Structure. Your building must be able to carry the added weight of the array.
- Lease term. Most commercial rooftop leases run about 20 years, often with annual rent increases.
Does the federal tax credit deadline affect my roof lease offer?
Yes. The federal commercial solar tax credit (Section 48E, 30% for most commercial projects) is claimed by the project owner, not the building owner, but it is built into what a developer can afford to pay you. Under current law, solar projects that did not begin construction by July 4, 2026 must be placed in service by December 31, 2027 to qualify (IRS Notice 2025-42). A project finished after that date may receive no federal credit at all.
Solar projects take time. Design, permitting, utility interconnection and construction all have to be finished before the deadline, and utility approvals can be slow. Our commercial solar installation guide walks through all six phases, which typically take 7 to 12 months from first conversation to Permission to Operate. For a roof starting now, that leaves about 14 months. If you are thinking about leasing your roof, or replacing it, starting this fall gives you the best chance of a deal that captures the full incentive.
