Poland: solar plant site data
Solar power plant in Słupsk, Poland: yield, tilt angle and row spacing
Słupsk: 1,014 kWh per kWp a year at the optimal tilt of 40°, 2° west of south (PVGIS). 4.8% below the median of the main cities of Poland (1,065). #83 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 9.0% less here.
Słupsk is in Pomeranian Voivodeship. Population 98,608 (GeoNames). 18 m above sea level. 63 km away: Koszalin, the nearest bigger city, 1,019 kWh/kWp — 0.5% less here. 19.55 m between rows, pitch 23.21 m, GCR 0.21 (latitude 54.5°).

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.
