Poland: solar plant site data
Solar power plant in Tczew, Poland: yield, tilt angle and row spacing
Tczew: 1,059 kWh per kWp a year at the optimal tilt of 41°, 2° east of south (PVGIS). 0.6% below the median of the main cities of Poland (1,065). #56 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 5.0% less here.
Tczew is in Pomeranian Voivodeship. Population 60,133 (GeoNames). 29 m above sea level. 30 km away: Gdansk, the nearest bigger city, 1,067 kWh/kWp — 0.8% less here. 19.14 m between rows, pitch 22.75 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.
