Estimates only

Electricity rates, monthly bills, solar production, savings and payback periods are estimates based on public data from the EIA and NREL PVWatts, plus standard assumptions (such as 900 kWh per month, a 6 kW system and about $3.00 per watt). Your actual results depend on your home, roof, usage, installer, financing and local rules.

Not professional advice

Nothing on this site is financial, tax, legal or engineering advice. Incentives such as tax credits and net metering rules can change. Always check details with a qualified professional and your utility before you buy.

Data accuracy

We update data regularly, but sources can be delayed, revised or temporarily unavailable. We cannot guarantee that all information is complete or current.

Installers and sponsored listings

Installers in our directory are independent companies. Sponsored listings are clearly labeled. A listing is not an endorsement, and we are not responsible for the work, prices or contracts of any installer.

AI-generated advice

Some explanations are generated by AI from the data we load. They can contain mistakes and should be treated as a starting point only.
