Solar power plant in San Sebastián de los Reyes, Spain: yield, tilt angle and row spacing
San Sebastián de los Reyes: 1,613 kWh per kWp a year at the optimal tilt of 37°, 4° east of south (PVGIS). Exactly the median of the main cities of Spain (1,615). #78 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 44.8% more here.
San Sebastián de los Reyes is in Community of Madrid. Population 75,912 (GeoNames). 685 m above sea level. 2 km away: Alcobendas, the nearest bigger city, 1,628 kWh/kWp — 0.9% less here. 6.84 m between rows, pitch 10.66 m, GCR 0.45 (latitude 40.6°).

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.
