Not sure which system size matches your home?
Start with the Solar System Size by Electric Bill calculator if you only know your average monthly bill, or use the Solar Panel Calculator if you know annual kWh. Then return here to compare cost scenarios for the nearest standard system size.

Installed solar prices vary by market, roof, electrical scope, equipment and financing. These pages show the arithmetic at clearly labeled cost-per-watt values instead of presenting a single generic number as a guaranteed market price.
