Enter your monthly power bill and pick your state. We'll show your system size, install cost, and the year you break even — with real 2026 numbers, not the expired 30% tax-credit math you'll see everywhere else.
We'll price a real system for your roof and bill — free, no pressure.
We start with your bill. At your state's power rate, your bill tells us how many kilowatt-hours you burn each year. We size a system to cover that usage (using local sun-hours and an 80% real-world derate), price it at $2.75 per watt installed, and compare that cost to what you'd otherwise pay the utility over 25 years — with your panels degrading about 0.5% a year and power rates climbing at the rate you set. Payback is simply the install cost divided by your first-year savings. Because Florida power is cheap and California power is expensive, the exact same bill pays off far faster in California than in Florida — the tool shows you your number.
