Germany: solar plant site data
Solar power plant in Bochum, Germany: yield, tilt angle and row spacing
Bochum: 1,020 kWh per kWp a year at the optimal tilt of 39°, 2° east of south (PVGIS). 2.4% below the median of the main cities of Germany (1,045). #136 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 8.4% less here.
Bochum is in North Rhine-Westphalia. Population 385,729 (GeoNames). 102 m above sea level. 14 km away: Essen, the nearest bigger city, the same 1,024 kWh/kWp. 14.26 m between rows, pitch 17.98 m, GCR 0.27 (latitude 51.5°).

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.
