Germany: solar plant site data
Solar power plant in Offenburg, Germany: yield, tilt angle and row spacing
Offenburg: 1,137 kWh per kWp a year at the optimal tilt of 38°, facing south (PVGIS). 8.8% above the median of the main cities of Germany (1,045). #8 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 2.0% more here.
Offenburg is in Baden-Württemberg. Population 59,238 (GeoNames). 163 m above sea level. 54 km away: Freiburg im Breisgau, the nearest bigger city, 1,120 kWh/kWp — 1.4% more here. 11.05 m between rows, pitch 14.82 m, GCR 0.32 (latitude 48.5°).

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.
