Spain: solar plant site data
Solar power plant in Ceuta, Spain: yield, tilt angle and row spacing
Ceuta: 1,592 kWh per kWp a year at the optimal tilt of 31°, 7° west of south (PVGIS). 1.4% below the median of the main cities of Spain (1,615). #95 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 42.9% more here.
Population 83,179 (GeoNames). 22 m above sea level. 30 km away: Algeciras, the nearest bigger city, the same 1,591 kWh/kWp. 4.74 m between rows, pitch 8.84 m, GCR 0.54 (latitude 35.9°).

Yield by month
July: 169 kWh/kWp, December: 96 — 1.8 times less.
February: 105 against the median of 114 for the main cities of Spain, 7.9% less.

| 15° | 1,539 | −3.3% |

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.
