Spain: solar plant site data
Solar power plant in Cadiz, Spain: yield, tilt angle and row spacing
Cadiz: 1,707 kWh per kWp a year at the optimal tilt of 33°, 3° west of south (PVGIS). 5.7% above the median of the main cities of Spain (1,615). #18 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 53.3% more here.
Cadiz is in the province of Cádiz, Andalusia. Population 116,979 (GeoNames). 22 m above sea level. 22 km away: Jerez de la Frontera, the nearest bigger city, the same 1,711 kWh/kWp. 5.15 m between rows, pitch 9.16 m, GCR 0.52 (latitude 36.5°).

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

| 33° (optimum) | 1,707 | — |
| 15° | 1,635 | −4.2% |
| 30° | 1,704 | −0.2% |

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.
