Spain: solar plant site data
Solar power plant in Ávila, Spain: yield, tilt angle and row spacing
Ávila: 1,531 kWh per kWp a year at the optimal tilt of 35°, 4° east of south (PVGIS). 5.3% below the median of the main cities of Spain (1,615). #123 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 37.4% more here.
Ávila is in the province of Ávila, Castile and León. Population 57,657 (GeoNames). 1,127 m above sea level. 59 km away: Collado Villalba, the nearest bigger city, 1,582 kWh/kWp — 3.2% less here. 6.55 m between rows, pitch 10.47 m, GCR 0.46 (latitude 40.7°).

| 15° | 1,460 | −4.6% |

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.
