Germany: solar plant site data
Solar power plant in Stolberg (Rhld.), Germany: yield, tilt angle and row spacing
Stolberg (Rhld.): 1,028 kWh per kWp a year at the optimal tilt of 38°, 7° east of south (PVGIS). 1.6% below the median of the main cities of Germany (1,045). #121 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 7.7% less here.
Stolberg (Rhld.) is in North Rhine-Westphalia. Population 57,684 (GeoNames). 185 m above sea level. 10 km away: Aachen, the nearest bigger city, 1,054 kWh/kWp — 2.5% less here. 13.15 m between rows, pitch 16.92 m, GCR 0.28 (latitude 50.8°).

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.
