Solar power plant in Cuenca, Spain: yield, tilt angle and row spacing

Cuenca: 1,609 kWh per kWp a year at the optimal tilt of 36°, 5° east of south (PVGIS). Exactly the median of the main cities of Spain (1,615). #80 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 44.4% more here.

Cuenca is in the province of Cuenca, Castilla–La Mancha. Population 54,898 (GeoNames). 941 m above sea level. 107 km away: Guadalajara, the nearest bigger city, the same 1,602 kWh/kWp. 6.52 m between rows, pitch 10.39 m, GCR 0.46 (latitude 40.1°).

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.
