For 2026, eligibility for the SEAI solar PV grant is expected to depend on factors such as whether you own the home, it has a valid electricity connection and it meets SEAI’s property-age requirements. You will generally need to apply before work starts and use an SEAI-registered solar PV company; installing panels before approval could affect eligibility. Grant rates and conditions may change, so the outcome is not guaranteed. Check the latest terms on the official SEAI website and confirm your position with a registered installer.
