Germany: solar plant site data
Solar power plant in Wetzlar, Germany: yield, tilt angle and row spacing
Wetzlar: 1,077 kWh per kWp a year at the optimal tilt of 38°, 1° east of south (PVGIS). 3.1% above the median of the main cities of Germany (1,045). #52 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 3.3% less here.
Wetzlar is in Hesse. Population 52,656 (GeoNames). 169 m above sea level. 12 km away: Giessen, the nearest bigger city, 1,060 kWh/kWp — 1.6% more here. 12.92 m between rows, pitch 16.69 m, GCR 0.29 (latitude 50.6°).

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.
