What we checked before giving you this answer
We reviewed Lawrence Berkeley National Laboratory's annual Tracking the Sun dataset, the National Renewable Energy Laboratory's residential solar modeling tools, peer-reviewed economic analyses of solar payback periods across different utility rate environments, and real homeowner cost data compiled by EnergySage from over 50,000 solar quotes. We did not simply repeat installer marketing claims or government talking points — we looked at what the actual installation and savings data shows across a wide range of home types, climates, and electricity markets.
-
Federal incentive status confirmed The 30% Residential Clean Energy Credit remains in effect under the Inflation Reduction Act through at least 2032, confirmed via IRS guidance and the U.S. Department of Energy.
-
Real-world payback periods cross-checked Lawrence Berkeley National Laboratory's Tracking the Sun 2024 report shows median payback of 7–9 years nationally, with wide variation by state electricity rates — not the "5-year payback" installers often advertise.
-
Home value impact verified A Zillow analysis of 1.4 million home sales found solar installations added an average of 4.1% to resale value, confirming solar has real upside even for homeowners who sell before full payback.
-
Lease vs. loan vs. cash purchase outcomes compared EnergySage's marketplace data confirms that cash purchases and solar loans outperform leases significantly over a 20-year horizon — leases save money but leave most of the financial benefit with the installer.
The right way to go solar depends on your situation — here's how to choose
Not every solar path makes equal financial sense. How you pay for the system, and whether you own or lease, changes your total return substantially over 20 years.
Common mistakes that make solar a bad deal
A few very common decisions cause homeowners to get poor results from solar — not because the technology doesn't work, but because the financial structure was wrong from the start.
-
Signing a solar lease without reading the escalator clause — Many leases include annual payment increases of 2–3% per year; over 20 years this can erode or eliminate your savings entirely, especially if utility rates rise more slowly than expected.
-
Getting only one installer quote — EnergySage data shows homeowners who collect only one quote pay an average of $2,900 more than those who compare three or more proposals for equivalent systems.
-
Installing solar on a roof that needs replacement within 5 years — Removing and reinstalling panels for a roof replacement costs $1,500–$6,000 and is almost never covered under installer warranties; if your roof is older than 15–18 years, replace it first.
-
Assuming net metering will always pay you full retail rates — Several states — including California, which shifted to NEM 3.0 in 2023 — have reduced the credit paid for energy exported to the grid by 75% or more. Always confirm your utility's current net metering policy before sizing a system, as oversizing for export now pays back far more slowly than it did before 2023.

We were paying $280–$340 a month in summer. Got three quotes through EnergySage, ended up going with a 10.5 kW system for $27,400 before credits. After the federal tax credit hit our return, net cost was around $19,200. Our bill is now $22 a month — the grid connection fee. Payback will be around 6.5 years by my math. I'd do it again tomorrow.

Portland isn't the sunniest place but our utility rates are rising fast. Installed 8.2 kW last spring, financed at 6.49% over 12 years. My loan payment is $148/month and my old bill was $165. So I'm cash-flow positive immediately, and the system is paid off years before the loan ends. The state of Oregon also gave us a $2,500 rebate I didn't know about until the installer mentioned it — always ask about state programs.

I went with a lease because I didn't want to deal with the loan process and it seemed simple. Honestly, I save about $30 a month, which is fine — but I've since learned I could've owned the system outright with a loan and saved closer to $90–100 a month by now. The lease is also showing up as a lien on my property record which caused a hiccup when I tried to refinance my mortgage. I'm not unhappy but I wish someone had explained the difference before I signed.
