Solar power plant in Guadalajara, Spain: yield, tilt angle and row spacing
Guadalajara: 1,602 kWh per kWp a year at the optimal tilt of 37°, 5° east of south (PVGIS). 0.8% below the median of the main cities of Spain (1,615). #85 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 43.8% more here.
Guadalajara is in the province of Guadalajara, Castilla–La Mancha. Population 93,470 (GeoNames). 722 m above sea level. 23 km away: Alcalá de Henares, the nearest bigger city, 1,615 kWh/kWp — 0.8% less here. 6.86 m between rows, pitch 10.68 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.
