Spain: solar plant site data
Solar power plant in Pamplona, Spain: yield, tilt angle and row spacing
Pamplona: 1,404 kWh per kWp a year at the optimal tilt of 36°, facing south (PVGIS). 13.1% below the median of the main cities of Spain (1,615). #128 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 26.0% more here.
Pamplona is in Navarre. Population 208,243 (GeoNames). 460 m above sea level. 84 km away: Vitoria-Gasteiz, the nearest bigger city, 1,274 kWh/kWp — 10.2% more here. 7.49 m between rows, pitch 11.36 m, GCR 0.42 (latitude 42.8°).

Yield by month
July: 160 kWh/kWp, December: 71 — 2.3 times less.
December: 71 against the median of 103 for the main cities of Spain, 31.1% less.

Fixed tilt facing south
What a table yields at another tilt than the optimal 36° — for roofs and frames with a standard slope.
| Tilt | A year | Against the optimum |

| 15° | 1,331 | −5.2% |
| 30° | 1,397 | −0.5% |

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.
