Poland: solar plant site data
Solar power plant in Leszno, Poland: yield, tilt angle and row spacing
Leszno: 1,075 kWh per kWp a year at the optimal tilt of 40°, 4° east of south (PVGIS). 0.9% above the median of the main cities of Poland (1,065). #28 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 3.5% less here.
Leszno is in Greater Poland Voivodeship. Population 63,565 (GeoNames). 90 m above sea level. 39 km away: Głogów, the nearest bigger city, 1,098 kWh/kWp — 2.1% less here. 15.04 m between rows, pitch 18.70 m, GCR 0.26 (latitude 51.8°).

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.
