Poland: solar plant site data
Solar power plant in Legionowo, Poland: yield, tilt angle and row spacing
Legionowo: 1,035 kWh per kWp a year at the optimal tilt of 39°, 3° east of south (PVGIS). 2.8% below the median of the main cities of Poland (1,065). #75 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 7.1% less here.
Legionowo is in Masovian Voivodeship. Population 50,786 (GeoNames). 77 m above sea level. 20 km away: Warsaw, the nearest bigger city, 1,053 kWh/kWp — 1.7% less here. 15.49 m between rows, pitch 19.21 m, GCR 0.25 (latitude 52.4°).

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.
