Understanding solar leases and power purchase agreements
Solar leases and power purchase agreements (PPAs) let homeowners get solar electricity without buying the system outright. They are financing structures where a third party installs and owns the panels, and the homeowner pays for the electricity or a fixed lease rate.
Basic structures
- Solar lease: You pay a fixed monthly lease payment for use of the equipment, often with little or no upfront cost. The host company owns and maintains the system.
- Power purchase agreement: You pay only for the solar electricity produced, usually at a set rate per kilowatt-hour that is lower than utility rates. The system owner is responsible for maintenance.
Key pros
- Minimal or no upfront cost to start generating solar energy.
- Maintenance and performance responsibility typically lie with the system owner.
- Predictable monthly payments that may be lower than current electric bills.
Key cons
- No ownership: You don’t receive tax credits or direct incentives, since the third party claims those benefits.
- Home sale complications: Buyers may need to accept or refinance the contract; leases and PPAs can complicate home transactions.
- Long-term costs: Over extended time frames, buying may offer greater savings than a lease or PPA.
What to review before signing
- Contract length and escalation clauses: Know how payments change over time.
- Performance guarantees and uptime commitments.
- Transfer terms if you sell the home and responsibilities for removal or relocation.
- Early termination fees, maintenance responsibilities and insurance coverage.
Alternatives
Solar loans and cash purchases give homeowners ownership, access to tax credits and better long-term value if you plan to stay in the home. Evaluate total lifetime costs, incentives and your plans for the property when choosing between ownership and third-party arrangements.
Carefully review contract terms, compare offers and consult with a trusted advisor or attorney if unsure. A clear understanding of responsibilities and long-term financial impacts helps you decide the best path for your situation.
