Solar Lease
A financing arrangement in which a third-party owner installs a solar system on a customer's property and charges a fixed monthly payment for the use of the equipment, regardless of how much electricity the system produces, with the owner capturing all tax credits and depreciation benefits.
A solar lease was, for much of the last decade, the dominant residential path to solar in the US. It solved the single hardest obstacle for homeowners, the 20,000 to 40,000 USD up-front capital requirement, by letting a third-party financier buy the system and charge a monthly that sat below the current utility bill. The homeowner got cheaper electricity, the financier got the tax credit and the long-term cash flow, and installers got a deal that would have died at the capital question.
The mechanics are straightforward. A specialty solar finance company owns the installed system for 20 to 25 years. The homeowner hosts the system on their roof and pays a flat monthly, often with a 1 to 3 percent annual escalator, regardless of how much electricity the panels produce. Maintenance and monitoring usually sit with the owner, which is a common selling point. At end of term, the customer can extend, buy out the system, or have it removed.
Where the model gets complicated
Leases have lost ground to solar loans in most US markets since 2020, for two reasons. First, as loan products became cheaper and more widely available, the math started to favor ownership, because the homeowner keeps the ITC and the depreciating-to-zero monthly-payment structure builds equity. Second, leases create complications at home sale, some buyers refuse to assume the lease, and a forced buyout right before listing can wipe out months of planning.
Leases still make sense for homeowners who do not have enough tax liability to use the ITC and who want a predictable monthly payment without taking on debt. A rep who reflexively recommends a loan over a lease without checking the customer's tax position is giving bad advice to a subset of customers.
Why it matters for solar installers
Installers that sell only leases, or only loans, leave money on the table. The real skill is knowing which customer wants which structure and presenting the right one first. SolarVis models lease, loan, cash, and PPA side by side inside the proposal, so the rep can let the customer's own math point at the answer.
Common questions
- How is a solar lease different from a PPA?
- A lease charges a fixed monthly payment for hardware usage, a PPA charges per kWh of actual production. Under a lease, the customer's payment does not change if the system underperforms, which shifts production risk to the customer. Under a PPA, the customer only pays when the system generates, which shifts production risk to the owner.
- Does the customer get the tax credit on a leased system?
- No. The third-party owner claims the Investment Tax Credit, depreciation, and any state incentives, because they legally own the system. The customer benefits indirectly through a lower monthly payment that reflects the financier having monetized those incentives.
- Can a customer buy out the lease and own the system?
- Most leases include buyout options at year 5, 10, or end of term, priced at fair market value. Some newer agreements offer fixed buyout schedules. Customers buying the system out after the tax benefits have been claimed need to verify the price is not above the market for an equivalent used system.
