Germany: solar plant site data
Solar power plant in Arnsberg, Germany: yield, tilt angle and row spacing
Arnsberg: 979 kWh per kWp a year at the optimal tilt of 38°, 2° west of south (PVGIS). 6.3% below the median of the main cities of Germany (1,045). #189 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 12.1% less here.
Arnsberg is in North Rhine-Westphalia. Population 74,879 (GeoNames). 295 m above sea level. 26 km away: Iserlohn, the nearest bigger city, 985 kWh/kWp — 0.6% less here. 13.84 m between rows, pitch 17.61 m, GCR 0.27 (latitude 51.4°).

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.
