FAQs
How accurate is this solar calculator?
Our estimates are 80–90% accurate compared to real installer quotes. On a typical $25,000 system, that means your estimate is within $2,500–$5,000 of what an installer would actually propose — close enough to know whether solar makes financial sense and to spot an overpriced quote. We use real irradiance data from the NREL PVWatts API for your exact ZIP code, EIA electricity rates by state, and a current market installation rate of $2.80/watt all-in. For a final price, you'll still need a site visit from a certified installer.
How much does solar save on average?
The average US homeowner saves roughly $1,300–$1,800 in the first year with solar on a typical system sized to a $150/month bill. Because utility rates tend to rise over time (our calculator assumes 4%/year), those savings compound — over 30 years that adds up to roughly $74,000–$101,000. The exact amount depends heavily on your state's electricity rate, sunlight hours, and system size.
What happened to the 30% federal solar tax credit?
The 30% federal residential solar tax credit (the Residential Clean Energy Credit, IRC Section 25D) ended for any system placed in service after December 31, 2025, repealed by the One Big Beautiful Bill Act with no phase-down. If you install in 2026 or later as a homeowner who buys or finances your system, there's no federal credit to claim. State, utility, and local incentives weren't affected by this change and still vary by location — check what's available where you live. Leased or PPA systems may still see some benefit passed through by the installer, who can claim a separate commercial credit.
How long does it take for solar to pay itself off?
Payback period varies widely by state — from as fast as 7–8 years in high-electricity-rate states like California and Hawaii, up to 17–20 years in low-rate states like Washington. Most homeowners fall somewhere around 10–14 years. These run longer than they used to now that the federal residential tax credit has ended — state and utility incentives, where available, can shorten it. After payback, all solar production is essentially free electricity.
Do I need a battery for solar panels?
Most grid-tied solar systems don't require a battery. Without one, your home uses solar during the day and draws from the grid at night. A Tesla Powerwall adds $11,500 to your system cost (two Powerwalls: $23,000) for backup power during outages and higher self-consumption — see our battery cost breakdown for details.
