Spain: solar plant site data
Solar power plant in Getxo, Spain: yield, tilt angle and row spacing
Getxo: 1,224 kWh per kWp a year at the optimal tilt of 36°, 3° west of south (PVGIS). 24.2% below the median of the main cities of Spain (1,615). #138 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 9.8% more here.
Getxo is in the province of Biscay, Basque Country. Population 80,770 (GeoNames). 43 m above sea level. 7 km away: Barakaldo, the nearest bigger city, 1,173 kWh/kWp — 4.4% more here. 7.71 m between rows, pitch 11.58 m, GCR 0.41 (latitude 43.4°).

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.
