Spain: solar plant site data
Solar power plant in Palma, Spain: yield, tilt angle and row spacing
Palma: 1,598 kWh per kWp a year at the optimal tilt of 36°, facing south (PVGIS). 1.1% below the median of the main cities of Spain (1,615). #91 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 43.5% more here.
Palma is in Balearic Islands. Population 438,234 (GeoNames). 34 m above sea level. 207 km away: Barcelona, the nearest bigger city, 1,572 kWh/kWp — 1.7% more here. 6.37 m between rows, pitch 10.24 m, GCR 0.47 (latitude 39.6°).

Yield by month
July: 163 kWh/kWp, December: 100 — 1.6 times less.
September: 136 against the median of 143 for the main cities of Spain, 4.9% 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° | 1,515 | −5.2% |
| 30° | 1,592 | −0.4% |

| 90° | 1,042 | −34.8% |
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.
