Solar power plant in Włocławek, Poland: yield, tilt angle and row spacing
Włocławek: 1,040 kWh per kWp a year at the optimal tilt of 39°, 3° east of south (PVGIS). 2.4% below the median of the main cities of Poland (1,065). #74 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 6.7% less here.
Włocławek is in Kuyavian-Pomeranian Voivodeship. Population 120,339 (GeoNames). 58 m above sea level. 45 km away: Płock, the nearest bigger city, 1,057 kWh/kWp — 1.6% less here. 15.85 m between rows, pitch 19.57 m, GCR 0.24 (latitude 52.6°).

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.
