Germany: solar plant site data
Solar power plant in Bremen, Germany: yield, tilt angle and row spacing
Bremen: 999 kWh per kWp a year at the optimal tilt of 40°, 4° east of south (PVGIS). 4.4% below the median of the main cities of Germany (1,045). #172 of 193 main cities of Germany by yield. For comparison, Kyiv: 1,114 kWh/kWp — 10.4% less here.
Population 546,501 (GeoNames). 17 m above sea level. 95 km away: Hamburg, the nearest bigger city, 990 kWh/kWp — 0.9% more here. 16.88 m between rows, pitch 20.54 m, GCR 0.23 (latitude 53.1°).

Yield by month
May: 126 kWh/kWp, December: 25 — 5.0 times less.
January: 29 against the median of 35 for the main cities of Germany, 17.1% less.

Fixed tilt facing south
What a table yields at another tilt than the optimal 40° — for roofs and frames with a standard slope.

| 15° | 932 | −6.7% |
| 30° | 988 | −1.0% |

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.
