Spain: solar plant site data
Solar power plant in Oviedo, Spain: yield, tilt angle and row spacing
Oviedo: 1,202 kWh per kWp a year at the optimal tilt of 38°, 4° east of south (PVGIS). 25.6% below the median of the main cities of Spain (1,615). #140 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 7.9% more here.
Oviedo is in Asturias. Population 220,027 (GeoNames). 237 m above sea level. 24 km away: Gijón, the nearest bigger city, 1,181 kWh/kWp — 1.8% more here. 8.08 m between rows, pitch 11.85 m, GCR 0.40 (latitude 43.4°).

Yield by month
August: 120 kWh/kWp, December: 71 — 1.7 times less.
January: 74 against the median of 109 for the main cities of Spain, 32.1% less.

| 15° | 1,130 | −6.0% |

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.
