Germany: solar plant site data
Solar power plant in Darmstadt, Germany: yield, tilt angle and row spacing
Darmstadt: 1,076 kWh per kWp a year at the optimal tilt of 38°, 3° east of south (PVGIS). 3.0% above the median of the main cities of Germany (1,045). #53 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 3.4% less here.
Darmstadt is in Hesse. Population 167,029 (GeoNames). 148 m above sea level. 27 km away: Frankfurt am Main, the nearest bigger city, 1,082 kWh/kWp — 0.6% less here. 12.24 m between rows, pitch 16.01 m, GCR 0.30 (latitude 49.9°).

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.
