Spain: solar plant site data
Solar power plant in Valencia, Spain: yield, tilt angle and row spacing
Valencia: 1,632 kWh per kWp a year at the optimal tilt of 37°, 3° west of south (PVGIS). 1.1% above the median of the main cities of Spain (1,615). #55 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 46.5% more here.
Valencia is in the province of Valencia, Valencian Community. Population 824,340 (GeoNames). 15 m above sea level. 302 km away: Madrid, the nearest bigger city, 1,620 kWh/kWp — 0.7% more here. 6.49 m between rows, pitch 10.31 m, GCR 0.46 (latitude 39.5°).

Yield by month
July: 162 kWh/kWp, December: 108 — 1.5 times less.
January: 117 against the median of 109 for the main cities of Spain, 7.3% more.

| 15° | 1,537 | −5.8% |

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.
