Estimate your solar payback period and 25-year savings based on system cost, your electric bill and utility rate increases.
Estimate only. Prices, sun hours and rates vary by location and installer.
We estimate annual savings from the share of your bill solar offsets, divide cost by that for payback, and compound savings over 25 years with rising utility rates.

Forget the monthly-payment pitch — the number that matters is payback: how many years of avoided electric bills it takes to recoup your net cost. After that, the power is essentially free for the life of the system. Because utility rates rise every year, your annual savings grow too, which is why the 25-year total dwarfs the upfront cost in most sunny, high-rate markets.
Often 7–12 years, depending on cost, sun and electric rates.
Solar locks in your cost while utility prices keep rising, widening savings.
Most carry 25-year production warranties; many run longer.
No — it's an estimate.
