Solar power plant in Szczecin, Poland: yield, tilt angle and row spacing
Szczecin: 1,007 kWh per kWp a year at the optimal tilt of 40°, facing south (PVGIS). 5.4% below the median of the main cities of Poland (1,065). #86 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 9.6% less here.
Szczecin is in West Pomeranian Voivodeship. Population 395,513 (GeoNames). 149 m above sea level. 196 km away: Poznan, the nearest bigger city, 1,059 kWh/kWp — 4.9% less here. 17.49 m between rows, pitch 21.15 m, GCR 0.23 (latitude 53.4°).

| 15° | 940 | −6.7% |

Snow and wind loads
Snow and wind loads for a site in Poland follow PN-EN 1991-1-3 (snow) and PN-EN 1991-1-4 (wind) with the Polish National Annex (NA). Solispec computes loads by the Ukrainian DBN V.1.2-2 only, so this page shows no snow or wind values for Poland: 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.
