How much can you save with solar?
Enter your state and monthly electric bill — get a 25-year savings estimate, system size, and payback period in seconds.
Estimate your solar savings
Two quick inputs. We use your state's real electricity rate and sun hours.
Solar savings by state
Electricity rates, sun hours, and incentives vary a lot by state. See your local estimate:
How the estimate works
We turn your monthly bill into annual energy use, size a system to cover it using your state's average peak sun hours, then apply the national average installed cost of $3.00/watt. Note: the federal residential solar tax credit (25D) was eliminated for new installations after December 31, 2025 — our model uses no federal credit for 2026. Lifetime savings assume a 3%/yr utility rate increase and normal panel degradation.
It's a transparent ballpark — not a binding quote. For exact numbers, compare local installer quotes.
Why go solar now?
The federal residential solar tax credit was eliminated for new installations after December 31, 2025. But electricity prices keep rising — up ~3%/year nationally — and locking in your own solar generation hedges against future rate hikes. State incentives and net metering remain available in most states.
