Solar power plant in Gdansk, Poland: yield, tilt angle and row spacing

Gdansk: 1,067 kWh per kWp a year at the optimal tilt of 41°, 2° east of south (PVGIS). Exactly the median of the main cities of Poland (1,065). #41 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 4.2% less here.

Gdansk is in Pomeranian Voivodeship. Population 487,371 (GeoNames). 8 m above sea level. 245 km away: Poznan, the nearest bigger city, 1,059 kWh/kWp — 0.8% more here. 19.70 m between rows, pitch 23.31 m, GCR 0.21 (latitude 54.4°).

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.
