Poland: solar plant site data
Solar power plant in Zgierz, Poland: yield, tilt angle and row spacing
Zgierz: 1,058 kWh per kWp a year at the optimal tilt of 39°, facing south (PVGIS). 0.6% below the median of the main cities of Poland (1,065). #57 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 5.0% less here.
Zgierz is in Łódź Voivodeship. Population 58,036 (GeoNames). 187 m above sea level. 11 km away: Lodz, the nearest bigger city, the same 1,062 kWh/kWp. 14.73 m between rows, pitch 18.45 m, GCR 0.26 (latitude 51.9°).

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.
