Solar power plant in Potsdam, Germany: yield, tilt angle and row spacing

Potsdam: 1,041 kWh per kWp a year at the optimal tilt of 40°, facing south (PVGIS). Exactly the median of the main cities of Germany (1,045). #100 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 6.5% less here.

Potsdam is in Brandenburg. Population 184,754 (GeoNames). 34 m above sea level. 27 km away: Berlin, the nearest bigger city, 1,053 kWh/kWp — 1.1% less here. 15.82 m between rows, pitch 19.48 m, GCR 0.25 (latitude 52.4°).

Snow and wind loads

Snow and wind loads for a site in Germany follow DIN EN 1991-1-3/NA (snow load zone, Schneelastzone) and DIN EN 1991-1-4/NA (wind zone, Windzone). Solispec computes loads by the Ukrainian DBN V.1.2-2 only, so this page shows no snow or wind values for Germany: enter the characteristic values from these documents in the designer’s «Own snow S0» and «Own wind W0» fields.

The frame calculation for such a site is preliminary: before installation it must be checked by an engineer who works to the country’s standards.
