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

Saarbrücken: 1,081 kWh per kWp a year at the optimal tilt of 37°, 2° east of south (PVGIS). 3.5% above the median of the main cities of Germany (1,045). #48 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 3.0% less here.

Saarbrücken is in Saarland. Population 182,971 (GeoNames). 195 m above sea level. 104 km away: Karlsruhe, the nearest bigger city, 1,135 kWh/kWp — 4.8% less here. 11.41 m between rows, pitch 15.23 m, GCR 0.31 (latitude 49.2°).

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.
