Privacy

We do not collect personal data. This site sets no cookies, runs no analytics, has no accounts, and no forms that send anything anywhere.

The electricity usage, panel wattage and roof direction you enter are used only by JavaScript running in your own browser. They are never transmitted to us and never stored.

Advertising is served by third-party networks. Those networks may set their own cookies or use similar technologies to serve and measure ads, and they have their own privacy policies. We do not receive the details of those uses beyond what a normal ad impression exposes.
