Poland: solar plant site data
Solar power plant in Starachowice, Poland: yield, tilt angle and row spacing
Starachowice: 1,069 kWh per kWp a year at the optimal tilt of 39°, 5° east of south (PVGIS). Exactly the median of the main cities of Poland (1,065). #33 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 4.0% less here.
Starachowice is in Świętokrzyskie Voivodeship. Population 53,739 (GeoNames). 210 m above sea level. 25 km away: Ostrowiec Świętokrzyski, the nearest bigger city, 1,087 kWh/kWp — 1.6% less here. 13.73 m between rows, pitch 17.45 m, GCR 0.27 (latitude 51.0°).

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.
