Is it more cost-effective to lease or buy home solar panels?

Upfront cost vs. long term investment

The core trade-off between leasing and buying solar panels comes down to who pays the initial installation and who keeps the financial benefits. Buying typically means you own the system outright, paying $15,000 to $25,000 (before federal and local incentives) for a typical residential setup. Leasing requires $0 down or a small initial fee, with the installer owning the equipment and charging you a fixed monthly rate for the electricity it produces.

According to data from the Lawrence Berkeley National Laboratory’s annual Tracking the Sun report, homeowners who buy solar panels see an average payback period of 7 to 10 years, after which electricity is essentially free for the remaining 15 to 20 years of the panels’ lifespan. Leasing, by contrast, locks you into a monthly payment that typically escalates 2 to 3 percent each year, reducing the net savings over time.

How incentives affect the math

Federal and state incentives strongly favor buying. The federal Investment Tax Credit (ITC) allows you to deduct 30 percent of the total system cost from your federal taxes. If you lease, the installer claims that credit, not you. Many states also offer performance-based incentives or rebates that go directly to the owner. For a typical 6 kW system in a state with moderate sunlight, the ITC alone can save $4,500 to $7,500.

Local incentives vary widely. Check your utility’s net metering policy and any state-specific solar renewable energy certificates (SRECs) programs. These programs can add thousands in value over the first few years, but only if you own the system.

Maintenance and warranty considerations

Solar panels require very little maintenance. Rain cleans most dust off tilted panels, and inverters typically last 10 to 15 years. If you buy, you are responsible for repairs after the manufacturer’s warranty expires (usually 25 years for panels, 10 to 12 for inverters). If you lease, the installer covers all repairs and replacements for the lease term.

However, leasing contracts often run 20 to 25 years and include an annual escalator clause. If you sell your home before the lease ends, the new buyer must qualify to take over the lease, which can complicate the sale. With a purchased system, the panels are an asset that can increase your home’s resale value by an average of 4 percent, according to a Zillow study.

Roof condition and system removal

Leasing companies typically perform a roof inspection before installation, but they may not replace your roof if it needs work. If you need a new roof during the lease term, you could face removal and reinstallation fees that you must pay. Buying gives you full control to schedule the roof work on your own timeline, though you still pay for any panel removal and reinstallation.

For a roof that is less than 10 years old and in good condition, buying is generally more cost effective over the full system life. For a roof that needs replacement within the next 5 to 7 years, leasing may be simpler initially, but you should get a written estimate for future removal costs before signing any contract.

Decision checklist

1. Budget check: Do you have $15,000 to $25,000 available or access to low interest financing? If yes, buying is likely more cost effective. If no, leasing may be your only entry point.
2. Roof age: Is your roof less than 10 years old and in good condition? If yes, buying makes sense. If it is older or has issues, factor in replacement costs.
3. Resale plans: Do you plan to stay in the home for 7+ years? If yes, buying recovers its cost. If you plan to sell sooner, leasing may be less disruptive.
4. Incentive access: Can you use the federal ITC (have enough tax liability)? If yes, buying gives you that benefit. If not, you lose nothing by leasing.
5. Risk tolerance: Are you comfortable managing your own maintenance? If yes, buying gives you control. If you prefer a hands-off arrangement, leasing offers convenience.

Final considerations

There is no universally correct answer. The most cost effective choice depends on your specific financial situation, local utility rates, and how long you plan to live in the home. Obtain at least three quotes for both purchase and lease options from licensed installers, and review each contract’s escalation rate, termination fees, and transfer terms. Given that climate, net metering policies, and permit requirements vary by location, consult with a local solar professional about the rules that apply to your address.
