HOW ACCURATE IS THIS?
Most calculators ask for your ZIP code and guess from an average. This one measures your actual roof, reads your utility's published rates, and models your production hour by hour — on the tools the industry runs on.
It is still an estimate. We use a typical household's pattern of electricity use, and yours will differ — an electric car, or someone home all day, moves it. Checking that against a year of your real meter data is the one thing we cannot do from here, and the first thing a good installer will.
