Poland: solar plant site data
Solar power plant in Suwałki, Poland: yield, tilt angle and row spacing
Suwałki: 1,018 kWh per kWp a year at the optimal tilt of 40°, 3° east of south (PVGIS). 4.4% below the median of the main cities of Poland (1,065). #81 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 8.6% less here.
Suwałki is in Podlaskie Voivodeship. Population 69,222 (GeoNames). 177 m above sea level. 110 km away: Bialystok, the nearest bigger city, the same 1,017 kWh/kWp. 18.80 m between rows, pitch 22.46 m, GCR 0.21 (latitude 54.1°).

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.
