Solar Panel Installers in Donegal

Check that the installer is on the SEAI register — this is required to claim the €1,800 grant.

Look for companies with Google or Trustpilot reviews and check they offer a workmanship warranty of at least 5 years alongside the panel manufacturer warranty (typically 25 years).

Prices vary by installer, roof type (slate, tile, flat), scaffolding requirements, and whether a battery is included. Always get itemised quotes so you can compare like for like.
