Spain: solar plant site data
Solar power plant in Ciudad Real, Spain: yield, tilt angle and row spacing
Ciudad Real: 1,638 kWh per kWp a year at the optimal tilt of 35°, 2° east of south (PVGIS). 1.4% above the median of the main cities of Spain (1,615). #51 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 47.0% more here.
Ciudad Real is in the province of Ciudad Real, Castilla–La Mancha. Population 74,743 (GeoNames). 633 m above sea level. 97 km away: Toledo, the nearest bigger city, the same 1,633 kWh/kWp. 6.05 m between rows, pitch 9.97 m, GCR 0.48 (latitude 39.0°).

| 15° | 1,559 | −4.9% |
| 30° | 1,632 | −0.4% |

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.
