Solar PPA Explained: What a Power Purchase Agreement Means
Understand solar power purchase agreements, who owns the equipment, how price escalators work, and the contract questions to ask before signing.
Quick answer
In a solar PPA, a third party generally owns the equipment and the homeowner pays for the electricity it produces under a contract. Review price, escalator, term, transfer, and end-of-contract options carefully.
Ownership changes the agreement
A PPA is not the same as buying a system. The equipment owner, maintenance responsibilities, incentives, and sale-of-home process can all differ from a cash purchase or loan.
Read the price schedule
The first-year per-kWh price is not the only cost. Ask whether the contract includes an annual escalator, minimum payment, production terms, and how the price compares with your current utility tariff.
Understand the home-sale path
A buyer may need to assume the agreement or another arrangement may be needed. Ask for the written transfer process before listing the home, not after a buyer appears.
Compare it with other offers
Use the same annual usage, system production, utility assumptions, and time horizon when comparing a PPA against purchase or loan options.
