How we selected these installers

  • SEAI registration is required. Only installers on the public SEAI register are eligible. homeowners need this to claim the €1,800 grant.
  • Home-county presence first. Installers headquartered in Roscommon fill the list before installers from neighbouring counties.
  • Google reviews rating and volume. Score = average rating × log10(review count + 1). This rewards consistent ratings across many jobs over a single perfect review.
  • Word of mouth and Facebook groups. We monitor the major Irish solar PV Facebook communities for which installers homeowners actually recommend, and which ones come up for the wrong reasons.
