Solar power plant in Gorzów Wielkopolski, Poland: yield, tilt angle and row spacing
Gorzów Wielkopolski: 1,045 kWh per kWp a year at the optimal tilt of 40°, 4° east of south (PVGIS). 1.9% below the median of the main cities of Poland (1,065). #69 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 6.2% less here.
Gorzów Wielkopolski is in Lubusz Voivodeship. Population 114,567 (GeoNames). 42 m above sea level. 89 km away: Szczecin, the nearest bigger city, 1,007 kWh/kWp — 3.8% more here. 16.33 m between rows, pitch 19.99 m, GCR 0.24 (latitude 52.7°).

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.
