Germany: solar plant site data
Solar power plant in Dorsten, Germany: yield, tilt angle and row spacing
Dorsten: 1,021 kWh per kWp a year at the optimal tilt of 39°, 3° east of south (PVGIS). 2.2% below the median of the main cities of Germany (1,045). #131 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 8.3% less here.
Dorsten is in North Rhine-Westphalia. Population 79,981 (GeoNames). 36 m above sea level. 9 km away: Marl, the nearest bigger city, 1,015 kWh/kWp — 0.7% more here. 14.48 m between rows, pitch 18.20 m, GCR 0.26 (latitude 51.7°).

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.
