Quote comparison
Enter the numbers from two or three proposals. We line them up on price per watt, warranty, financing and production, and tell you which is cheapest, which is the best value, and which is the best overall package.
All figures come from the proposals you enter. "$/W" is total price ÷ (kW × 1000), before incentives. Production is estimated at ~1,400 kWh/kW/yr if you don't enter it. This is a decision aid, not financial advice.
