Spain: solar plant site data
Solar power plant in Santiago de Compostela, Spain: yield, tilt angle and row spacing
Santiago de Compostela: 1,301 kWh per kWp a year at the optimal tilt of 35°, 4° west of south (PVGIS). 19.5% below the median of the main cities of Spain (1,615). #134 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 16.8% more here.
Santiago de Compostela is in the province of A Coruña, Galicia. Population 99,536 (GeoNames). 257 m above sea level. 56 km away: A Coruña, the nearest bigger city, 1,282 kWh/kWp — 1.5% more here. 7.33 m between rows, pitch 11.25 m, GCR 0.43 (latitude 42.9°).

| 15° | 1,236 | −5.0% |

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.
