Solar power plant in Opole, Poland: yield, tilt angle and row spacing
Opole: 1,095 kWh per kWp a year at the optimal tilt of 40°, 2° east of south (PVGIS). 2.8% above the median of the main cities of Poland (1,065). #6 of 87 main cities of Poland by yield. For comparison, Kyiv: 1,114 kWh/kWp — 1.7% less here.
Opole is in Opole Voivodeship. Population 127,676 (GeoNames). 173 m above sea level. 67 km away: Gliwice, the nearest bigger city, 1,082 kWh/kWp — 1.3% more here. 13.62 m between rows, pitch 17.28 m, GCR 0.28 (latitude 50.7°).

| 15° | 1,020 | −6.9% |

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.
