Solar power plant in Tarragona, Spain: yield, tilt angle and row spacing
Tarragona: 1,568 kWh per kWp a year at the optimal tilt of 38°, 1° west of south (PVGIS). 3.0% below the median of the main cities of Spain (1,615). #113 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 40.7% more here.
Tarragona is in the province of Tarragona, Catalonia. Population 141,542 (GeoNames). 60 m above sea level. 76 km away: L'Hospitalet de Llobregat, the nearest bigger city, 1,597 kWh/kWp — 1.8% less here. 7.19 m between rows, pitch 10.96 m, GCR 0.44 (latitude 41.1°).

| 15° | 1,465 | −6.5% |

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.
