Solar Calculator

Enter coordinates and system details to calculate solar panel output for any location in Europe. Powered by the EU PVGIS API.

Range: 34 to 62 (Europe)

Range: -10 to 35 (Europe)

Typical: 14% (inverter, cables, dirt, etc.)

About This Calculator

This calculator uses the EU Photovoltaic Geographical Information System (PVGIS) version 5.3, maintained by the European Commission Joint Research Centre. It provides solar radiation data and photovoltaic system performance estimates based on satellite observations.

Coverage: PVGIS covers Europe, Africa, parts of Asia, and South America. For European locations, latitude should be between 34° and 62°.

System losses account for inverter efficiency, cable losses, dirt on panels, and other real-world factors. The default 14% is a reasonable estimate for well-maintained systems.

Optimal angles: The calculator automatically determines the best tilt angle and orientation for maximum energy production at your location.
