Solar power plant in Erfurt, Germany: yield, tilt angle and row spacing
Erfurt: 1,050 kWh per kWp a year at the optimal tilt of 39°, 3° east of south (PVGIS). 0.5% above the median of the main cities of Germany (1,045). #91 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 5.7% less here.
Erfurt is in Thuringia. Population 218,793 (GeoNames). 194 m above sea level. 86 km away: Halle (Saale), the nearest bigger city, 1,078 kWh/kWp — 2.5% less here. 13.66 m between rows, pitch 17.38 m, GCR 0.28 (latitude 51.0°).

| 15° | 985 | −6.2% |

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.
