Spain: solar plant site data
Solar power plant in Dos Hermanas, Spain: yield, tilt angle and row spacing
Dos Hermanas: 1,672 kWh per kWp a year at the optimal tilt of 34°, 1° west of south (PVGIS). 3.5% above the median of the main cities of Spain (1,615). #28 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 50.1% more here.
Dos Hermanas is in the province of Seville, Andalusia. Population 122,943 (GeoNames). 45 m above sea level. 12 km away: Seville, the nearest bigger city, the same 1,672 kWh/kWp. 5.46 m between rows, pitch 9.43 m, GCR 0.51 (latitude 37.3°).

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.
