Germany: solar plant site data
Solar power plant in Gronau, Germany: yield, tilt angle and row spacing
Gronau: 1,011 kWh per kWp a year at the optimal tilt of 39°, 2° east of south (PVGIS). 3.2% below the median of the main cities of Germany (1,045). #156 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 9.2% less here.
Gronau is in North Rhine-Westphalia. Population 50,547 (GeoNames). 42 m above sea level. 25 km away: Nordhorn, the nearest bigger city, the same 1,008 kWh/kWp. 15.22 m between rows, pitch 18.94 m, GCR 0.25 (latitude 52.2°).

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.
