Solar potential in Germany

These figures are the unweighted mean of the city locations listed below, not a national average. Two urban points do not represent an entire country, its roofs or its solar installations.

Sampled-city benchmark

Estimated PV output1,096kWh/kWp/year
Solar irradiation1,374kWh/m²/year

PV output is estimated electricity from 1 kWp of installed solar panels. Irradiation is sunlight energy received per square meter on the optimally tilted panel plane; it is not electricity.

For a 5 kWp system, multiply the electricity values by five. This simple scaling does not account for roof-specific shading or equipment constraints.

Range across these cities: 1,052–1,141kWh/kWp/year. Panel tilt and direction are location-specific; see each city.

Monthly solar irradiation and PV output

Highest-output month: July · 127.5kWh/kWp/month. Lowest-output month: December · 39.1kWh/kWp/month.

The chart and table use the mean of the listed cities for each month.

Bar lengths compare monthly PV electricity output; exact output and irradiation values are in the table.

Data and methodology

PVGIS 5.3 (European Commission Joint Research Centre), crystalline silicon, fixed free-standing installation, 1 kWp, 14% system losses, equator-facing panels with optimized tilt and the terrain horizon. Long-term climate estimates are not a forecast or a roof survey. Nearby buildings, trees, roof constraints, snow and local conditions can change actual output.
