Spain: solar plant site data
Solar power plant in Castelldefels, Spain: yield, tilt angle and row spacing
Castelldefels: 1,585 kWh per kWp a year at the optimal tilt of 38°, 2° west of south (PVGIS). 1.9% below the median of the main cities of Spain (1,615). #101 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 42.2% more here.
Castelldefels is in the province of Barcelona, Catalonia. Population 66,375 (GeoNames). 14 m above sea level. 9 km away: Sant Boi de Llobregat, the nearest bigger city, 1,600 kWh/kWp — 1.0% less here. 7.25 m between rows, pitch 11.02 m, GCR 0.43 (latitude 41.3°).

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.
