About NorthSolarCalc

NorthSolarCalc is a free, independent solar savings calculator built for US and Canadian homeowners who want unbiased numbers — not a sales pitch.

We don't sell solar panels or represent any installer. Our goal is to give you an honest estimate so you can make an informed decision before getting quotes.

Our Data Sources

• Peak sun hours: NREL PVWatts Calculator

Data updated for 2025. All calculations are estimates — actual savings vary by roof, usage, and local installer pricing.
