Overview of Solar Panel Costs in Ireland

Solar Panels

Capacity factor of solar panels is limited primarily by geographic latitude and varies significantly depending on cloud cover, dust, day length and other factors. In the United Kingdom, seasonal capacity factor ranges from 2% (December) to 20% (July), with average annual capacity factor of 10–11%, while in Spain the value reaches 18%.[42] Globally, capacity factor for utility-scale PV farms was 16.1% in 2019.[43][unreliable source?]
