Spain: solar plant site data
Solar power plant in Madrid, Spain: yield, tilt angle and row spacing
Madrid: 1,620 kWh per kWp a year at the optimal tilt of 37°, 6° east of south (PVGIS). Exactly the median of the main cities of Spain (1,615). #66 of 147 main cities of Spain by yield. For comparison, Kyiv: 1,114 kWh/kWp — 45.5% more here.
Madrid is in Community of Madrid. Population 3,255,944 (GeoNames). 665 m above sea level. 6.79 m between rows, pitch 10.61 m, GCR 0.45 (latitude 40.4°).

| 15° | 1,528 | −5.7% |

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.
