What customers say on
Brilliant work
Mayo's surprising solar performance despite rainfall
Mayo is one of Ireland's wettest counties, but this is misleading for solar potential. Mayo's rainfall comes predominantly from Atlantic fronts that move through quickly — the county actually has more "broken cloud" days than persistently overcast days. Solar panels generate electricity in diffuse light too, not just direct sunshine. A 4kWp system in Castlebar or Westport still generates 3,300+ kWh per year, saving €1,000+ annually at current rates. The long summer days at Mayo's latitude (17+ hours of daylight in June) significantly boost peak-season generation.
