Solar power plant in Stuttgart, Germany: yield, tilt angle and row spacing
Stuttgart: 1,132 kWh per kWp a year at the optimal tilt of 39°, 2° east of south (PVGIS). 8.4% above the median of the main cities of Germany (1,045). #11 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 1.6% more here.
Stuttgart is in Baden-Württemberg. Population 612,663 (GeoNames). 252 m above sea level. 152 km away: Frankfurt am Main, the nearest bigger city, 1,082 kWh/kWp — 4.6% more here. 11.54 m between rows, pitch 15.26 m, GCR 0.31 (latitude 48.8°).

| 15° | 1,061 | −6.3% |
| 30° | 1,122 | −0.9% |

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.
