How it works

Three simple steps to plan your green energy system.

1. Set your location

Enter your address or use GPS. We fetch solar irradiance and wind data from NASA and Open-Meteo for your exact location.

2. Choose equipment

Browse our curated database of solar panels, wind turbines, batteries, and inverters. Compare specs side by side.

3. See your results

Get detailed energy production estimates, monthly breakdowns, savings projections, and environmental impact metrics.
