Spain: solar plant site data
Solar power plant in San Fernando, Spain: yield, tilt angle and row spacing
San Fernando: 1,737 kWh per kWp a year at the optimal tilt of 34°, 3° west of south (PVGIS). 7.5% above the median of the main cities of Spain (1,615). #10 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 55.9% more here.
San Fernando is in the province of Cádiz, Andalusia. Population 95,174 (GeoNames). 15 m above sea level. 10 km away: Cadiz, the nearest bigger city, 1,707 kWh/kWp — 1.7% more here. 5.27 m between rows, pitch 9.24 m, GCR 0.52 (latitude 36.5°).

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.
