Spain: solar plant site data
Solar power plant in Lugo, Spain: yield, tilt angle and row spacing
Lugo: 1,314 kWh per kWp a year at the optimal tilt of 35°, 10° west of south (PVGIS). 18.7% below the median of the main cities of Spain (1,615). #133 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 17.9% more here.
Lugo is in the province of Lugo, Galicia. Population 98,025 (GeoNames). 465 m above sea level. 79 km away: Ourense, the nearest bigger city, 1,354 kWh/kWp — 3.0% less here. 7.38 m between rows, pitch 11.30 m, GCR 0.42 (latitude 43.0°).

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.
