Spain: solar plant site data
Solar power plant in Soria, Spain: yield, tilt angle and row spacing
Soria: 1,538 kWh per kWp a year at the optimal tilt of 37°, 4° east of south (PVGIS). 4.8% below the median of the main cities of Spain (1,615). #122 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 38.1% more here.
Soria is in the province of Soria, Castile and León. Population 39,112 (GeoNames). 1,064 m above sea level. 78 km away: Logroño, the nearest bigger city, 1,418 kWh/kWp — 8.5% more here. 7.26 m between rows, pitch 11.08 m, GCR 0.43 (latitude 41.8°).

Yield by month
July: 165 kWh/kWp, November: 91 — 1.8 times less.
November: 91 against the median of 103 for the main cities of Spain, 11.7% less.

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.
