Spain: solar plant site data
Solar power plant in Avilés, Spain: yield, tilt angle and row spacing
Avilés: 1,215 kWh per kWp a year at the optimal tilt of 38°, facing south (PVGIS). 24.8% below the median of the main cities of Spain (1,615). #139 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 9.1% more here.
Avilés is in Asturias. Population 78,715 (GeoNames). 26 m above sea level. 21 km away: Gijón, the nearest bigger city, 1,181 kWh/kWp — 2.9% more here. 8.16 m between rows, pitch 11.93 m, GCR 0.40 (latitude 43.6°).

Snow and wind loads
Snow and wind loads for a site in Spain follow CTE DB SE-AE (Spain’s Código Técnico de la Edificación) and, where the Eurocodes are applied, UNE-EN 1991-1-3 and UNE-EN 1991-1-4 with the Spanish National Annex. Solispec computes loads by the Ukrainian DBN V.1.2-2 only, so this page shows no snow or wind values for Spain: 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.
