Spain: solar plant site data
Solar power plant in Segovia, Spain: yield, tilt angle and row spacing
Segovia: 1,507 kWh per kWp a year at the optimal tilt of 35°, 4° east of south (PVGIS). 6.7% below the median of the main cities of Spain (1,615). #124 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 35.3% more here.
Segovia is in the province of Segovia, Castile and León. Population 51,683 (GeoNames). 996 m above sea level. 36 km away: Collado Villalba, the nearest bigger city, 1,582 kWh/kWp — 4.7% less here. 6.64 m between rows, pitch 10.56 m, GCR 0.45 (latitude 40.9°).

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.
