Solar power plant in Karlsruhe, Germany: yield, tilt angle and row spacing

Karlsruhe: 1,135 kWh per kWp a year at the optimal tilt of 38°, facing south (PVGIS). 8.7% above the median of the main cities of Germany (1,045). #9 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 1.9% more here.

Karlsruhe is in Baden-Württemberg. Population 283,799 (GeoNames). 118 m above sea level. 54 km away: Mannheim, the nearest bigger city, 1,108 kWh/kWp — 2.5% more here. 11.48 m between rows, pitch 15.25 m, GCR 0.31 (latitude 49.0°).

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.
