Spain: solar plant site data
Solar power plant in Valladolid, Spain: yield, tilt angle and row spacing
Valladolid: 1,560 kWh per kWp a year at the optimal tilt of 36°, 2° east of south (PVGIS). 3.4% below the median of the main cities of Spain (1,615). #116 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 40.1% more here.
Valladolid is in the province of Valladolid, Castile and León. Population 300,618 (GeoNames). 702 m above sea level. 162 km away: Madrid, the nearest bigger city, 1,620 kWh/kWp — 3.7% less here. 7.05 m between rows, pitch 10.92 m, GCR 0.44 (latitude 41.7°).

| 15° | 1,477 | −5.3% |

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.
