Spain: solar plant site data
Solar power plant in Melilla, Spain: yield, tilt angle and row spacing
Melilla: 1,599 kWh per kWp a year at the optimal tilt of 33°, 5° west of south (PVGIS). 1.0% below the median of the main cities of Spain (1,615). #90 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 43.6% more here.
Population 85,985 (GeoNames). 14 m above sea level. 166 km away: Roquetas de Mar, the nearest bigger city, 1,779 kWh/kWp — 10.1% less here. 4.88 m between rows, pitch 8.89 m, GCR 0.54 (latitude 35.3°).

Yield by month
July: 155 kWh/kWp, November: 111 — 1.4 times less.
December: 112 against the median of 103 for the main cities of Spain, 8.7% more.

Fixed tilt facing south
What a table yields at another tilt than the optimal 33° — for roofs and frames with a standard slope.

| 15° | 1,534 | −4.1% |
| 30° | 1,595 | −0.3% |

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.
