Grant rates: €700/kWp for the first 2 kWp and €200/kWp from 2 to 4 kWp, capped at €1,800. Savings assume current electricity prices and typical Irish generation for a south-facing roof; a shaded or north-facing roof will generate less. Work must be done by an SEAI-registered installer, and the grant is claimed after installation.

Eligibility & Application

  • Must own your home (built before 2021)
  • BER certificate required after installation
  • Must use SEAI-registered contractor
  • Grant paid after installation and inspection
