Solar power plant in Bełchatów, Poland: yield, tilt angle and row spacing
Bełchatów: 1,059 kWh per kWp a year at the optimal tilt of 39°, 4° east of south (PVGIS). 0.6% below the median of the main cities of Poland (1,065). #54 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 4.9% less here.
Bełchatów is in Łódź Voivodeship. Population 62,896 (GeoNames). 202 m above sea level. 24 km away: Piotrkow Trybunalski, the nearest bigger city, 1,069 kWh/kWp — 0.9% less here. 14.12 m between rows, pitch 17.84 m, GCR 0.27 (latitude 51.4°).

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.
