Germany: solar plant site data
Solar power plant in Siegen, Germany: yield, tilt angle and row spacing
Siegen: 983 kWh per kWp a year at the optimal tilt of 37°, facing south (PVGIS). 5.9% below the median of the main cities of Germany (1,045). #186 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 11.8% less here.
Siegen is in North Rhine-Westphalia. Population 107,242 (GeoNames). 272 m above sea level. 66 km away: Koblenz, the nearest bigger city, 1,036 kWh/kWp — 5.1% less here. 12.96 m between rows, pitch 16.78 m, GCR 0.29 (latitude 50.9°).

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.
