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.
