Solar power plant in Jastrzębie Zdrój, Poland: yield, tilt angle and row spacing
Jastrzębie Zdrój: 1,074 kWh per kWp a year at the optimal tilt of 39°, facing south (PVGIS). 0.8% above the median of the main cities of Poland (1,065). #30 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 3.6% less here.
Jastrzębie Zdrój is in Silesian Voivodeship. Population 95,813 (GeoNames). 260 m above sea level. 16 km away: Rybnik, the nearest bigger city, the same 1,074 kWh/kWp. 12.59 m between rows, pitch 16.31 m, GCR 0.29 (latitude 50.0°).

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.
