Solar Lease vs Purchase Calculator

Purchase: Higher upfront cost, but you own the system and keep all the energy savings. The 30% federal residential credit ended for systems installed after 2025, so only state or utility incentives reduce the price now.

Lease: No upfront cost, but you pay monthly and the leasing company keeps any incentives. Check the escalator: many leases rise 2–3% a year, which this simple comparison does not include.

Tip: Purchase usually saves more money long-term if you can afford the upfront cost.
