Germany: solar plant site data
Solar power plant in Heilbronn, Germany: yield, tilt angle and row spacing
Heilbronn: 1,108 kWh per kWp a year at the optimal tilt of 38°, 1° east of south (PVGIS). 6.1% above the median of the main cities of Germany (1,045). #29 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 0.5% less here.
Heilbronn is in Baden-Württemberg. Population 120,733 (GeoNames). 173 m above sea level. 40 km away: Stuttgart, the nearest bigger city, 1,132 kWh/kWp — 2.1% less here. 11.59 m between rows, pitch 15.36 m, GCR 0.31 (latitude 49.1°).

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.
