Solar power plant in Rzeszów, Poland: yield, tilt angle and row spacing
Rzeszów: 1,078 kWh per kWp a year at the optimal tilt of 39°, 1° east of south (PVGIS). 1.2% above the median of the main cities of Poland (1,065). #22 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 3.2% less here.
Rzeszów is in Subcarpathian Voivodeship. Population 198,317 (GeoNames). 209 m above sea level. 140 km away: Lublin, the nearest bigger city, the same 1,080 kWh/kWp. 12.68 m between rows, pitch 16.40 m, GCR 0.29 (latitude 50.0°).

| 15° | 1,010 | −6.3% |

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.
