Spain: solar plant site data
Solar power plant in Puertollano, Spain: yield, tilt angle and row spacing
Puertollano: 1,617 kWh per kWp a year at the optimal tilt of 35°, 5° east of south (PVGIS). Exactly the median of the main cities of Spain (1,615). #72 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 45.1% more here.
Puertollano is in the province of Ciudad Real, Castilla–La Mancha. Population 51,842 (GeoNames). 701 m above sea level. 37 km away: Ciudad Real, the nearest bigger city, 1,638 kWh/kWp — 1.3% less here. 5.96 m between rows, pitch 9.88 m, GCR 0.48 (latitude 38.7°).

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.
