Solar power plant in Jaén, Spain: yield, tilt angle and row spacing
Jaén: 1,648 kWh per kWp a year at the optimal tilt of 34°, 11° east of south (PVGIS). 2.0% above the median of the main cities of Spain (1,615). #36 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 48.0% more here.
Jaén is in the province of Jaén, Andalusia. Population 113,457 (GeoNames). 558 m above sea level. 67 km away: Granada, the nearest bigger city, 1,673 kWh/kWp — 1.5% less here. 5.58 m between rows, pitch 9.55 m, GCR 0.50 (latitude 37.8°).

| 15° | 1,574 | −4.5% |

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.
