Frequently Asked Questions
How long does it take for solar panels to pay for themselves?
The average solar panel payback period in the US is 6–12 years, depending on your electricity bill, local sun hours, system cost, and incentives. With the 30% federal tax credit, many homeowners see payback in 7–9 years.
What is the federal solar tax credit in 2026?
The federal Investment Tax Credit (ITC) is 30% of your total solar system cost in 2026. This is a direct reduction in your federal tax bill, not just a deduction. It applies to both residential and commercial installations.
Are solar panels worth it if I plan to sell my home?
Generally yes — studies show solar panels increase home resale value by $15,000–$20,000 on average, often close to the net cost of installation. Even if you sell before breaking even on energy savings, you may recoup your investment through higher sale price.
How many peak sun hours does my area get?
Peak sun hours vary by location: Southwest US (Arizona, Nevada, California) averages 6–7 hours, the Southeast and Midwest average 4.5–5.5 hours, and the Northeast and Pacific Northwest average 3.5–4.5 hours. You can find your exact location using the NREL PVWatts tool.
Should I buy or lease solar panels?
Buying (outright or with a solar loan) is almost always the better financial decision. You own the system, qualify for the full tax credit, and keep all the savings. Leasing is simpler upfront but you forfeit the tax credit and long-term savings go to the leasing company.
