Solar Lease vs. Loan: An Honest Comparison
Compare solar lease vs loan side by side. Understand the real costs, ownership differences, and which option makes more financial sense for you.
The Fundamental Difference: Ownership
The most important difference between a solar lease and a solar loan is ownership. With a solar loan, you own the panels from day one. With a solar lease, the solar company owns the panels and you're renting them. This distinction has far-reaching financial and practical implications that extend well beyond the monthly payment amount.
Ownership means you receive the federal solar tax credit (currently 30% of system cost), which can be worth $6,000-$10,000 on a typical residential system. With a lease, the solar company receives this credit — not you. Ownership also means you build equity in the system, can sell it with your home as an asset, and have full control over the equipment and any future modifications.
Leasing means lower upfront commitment and no responsibility for maintenance (the leasing company handles repairs), but it also means 20-25 years of monthly payments with annual escalators, no tax credit benefit, and the complications of lease transfer or buyout when you sell your home.
Cost Comparison: Lease vs. Loan Over 25 Years
The total cost comparison between leasing and buying solar is more complex than it appears. A solar loan with a 6% interest rate on a $25,000 system over 12 years results in total payments of roughly $33,000 — but you own a $25,000 asset (depreciating over time) and received a $7,500 tax credit, making your effective net cost closer to $25,500.
A solar lease starting at $150/month with a 2.9% annual escalator results in total payments of roughly $65,000 over 25 years — and at the end, you own nothing. The lease company received the $7,500 tax credit. Your net cost for 25 years of electricity from the leased system is significantly higher than if you had purchased the system.
These numbers vary significantly based on system size, loan terms, local electricity rates, and net metering policies. But in most scenarios, purchasing a solar system (with a loan if necessary) results in better long-term economics than leasing — assuming you stay in the home long enough to recoup the investment.
When a Lease Might Make Sense
Despite the generally better economics of ownership, there are situations where a solar lease might make sense. If you have very low tax liability and wouldn't benefit significantly from the federal tax credit, the lease's lower upfront commitment may be attractive. If you're planning to sell your home in 5-7 years and the local real estate market is strong for solar, a lease might be acceptable if the buyout cost is reasonable.
If you're concerned about maintenance and repair costs, a lease transfers that responsibility to the solar company — though in practice, many lessees report difficulty getting timely service from their leasing company. If you simply can't qualify for a solar loan due to credit issues, a lease may be the only available financing option.
The key is to go in with eyes open. Understand the total cost of the lease over its full term, the implications for your home sale, and the exit options available to you. Don't sign a 25-year lease based on a salesperson's assurance that it's 'better than buying.'
