Spain: solar plant site data
Solar power plant in Toledo, Spain: yield, tilt angle and row spacing
Toledo: 1,633 kWh per kWp a year at the optimal tilt of 36°, 2° east of south (PVGIS). 1.1% above the median of the main cities of Spain (1,615). #54 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 46.6% more here.
Toledo is in the province of Toledo, Castilla–La Mancha. Population 86,526 (GeoNames). 533 m above sea level. 47 km away: Parla, the nearest bigger city, 1,647 kWh/kWp — 0.8% less here. 6.46 m between rows, pitch 10.33 m, GCR 0.46 (latitude 39.9°).

| 15° | 1,547 | −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.
