Solar Lease FAQ - Washington

Solar panel leases in Washington typically cost $32-$56 per month for a standard 6kW system with $0 down. Your actual lease payment depends on system size, the leasing company, and your specific location within Washington. Lease payments are designed to be lower than your current electricity bill, providing immediate monthly savings of approximately $11. Compare quotes from multiple Washington solar leasing companies to find the best rate.

Whether a solar lease or PPA is better in Washington depends on your preferences. A PPA in Washington typically offers rates around $0.09/kWh, which is below the local utility rate. PPAs are better if your energy usage varies seasonally, since you only pay for what the panels produce. A solar lease provides fixed monthly payments, which is better for predictable budgeting. Both options require $0 down and include maintenance. Compare offers from Washington providers offering both options.

For most Washington homeowners who can afford the upfront cost or qualify for a solar loan, buying provides 40-70% more savings over 25 years because you claim the 30% federal tax credit and keep all electricity savings. However, leasing is an excellent option if you want $0 upfront cost and maintenance-free solar energy in Washington. Leasing also makes sense if you have low tax liability and cannot fully benefit from the federal tax credit. Consider your budget, how long you plan to stay in your Washington home, and your financial goals.

Major solar leasing companies operating in Washington include national providers like Sunrun, SunPower, and Tesla Solar, as well as regional companies. Availability varies by location within Washington. When comparing Washington solar leasing companies, evaluate the monthly payment, annual escalator rate, performance guarantee, maintenance coverage, and end-of-lease options. We recommend getting quotes from at least 2-3 companies to compare terms and find the best deal for your Washington home.

Most solar leases in Washington include early termination provisions, but they typically involve paying a fee or the remaining lease balance. Some Washington leases offer a buyout option after 5-7 years at a predetermined price. If you are selling your Washington home, you can usually transfer the lease to the new buyer. Before signing a lease, carefully review the early termination terms, transfer process, and any associated fees. Negotiate favorable terms upfront, as Washington lease terms can vary significantly between providers.
