Spain: solar plant site data
Solar power plant in Cartagena, Spain: yield, tilt angle and row spacing
Cartagena: 1,667 kWh per kWp a year at the optimal tilt of 35°, 4° west of south (PVGIS). 3.2% above the median of the main cities of Spain (1,615). #32 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 49.6% more here.
Cartagena is in Region of Murcia. Population 213,943 (GeoNames). 1 m above sea level. 45 km away: Murcia, the nearest bigger city, 1,630 kWh/kWp — 2.3% more here. 5.68 m between rows, pitch 9.60 m, GCR 0.50 (latitude 37.6°).

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.
