Solar tools
Three tools built from the directories on this site. All run entirely in your browser: no form is sent anywhere, no account is needed, and no figure is invented. You bring the quotes and the state; the tools do the lining up and the arithmetic.
Solar quote comparison tool
Enter two or three quotes and your state. The tool ranks them by price per watt, estimates first-year production and simple payback from the recorded planning range for your state, and lists the recorded state programs to check against each quote.

Installer quote comparison worksheet
Enter up to three quotes you obtained: installer, system size, price, warranties and estimated production. The worksheet lines them up side by side and computes price per watt from your own numbers.

Incentives checklist by state
Pick a state and get the checklist of incentive and net metering items to verify for that state, built from the state incentives directory, with the official source for each item.

The directories behind the tools
The checklist and the quote comparison tool are built from the state incentives and net metering directory and the recorded planning range on each state page. The worksheet pairs with the national installers directory, where you can compare up to three companies across every recorded characteristic.
