An existing home may qualify for the SEAI Solar PV grant in 2026, provided it meets the scheme’s conditions, such as the relevant build date, ownership and electricity connection requirements. The installation generally needs to be completed by an SEAI-registered solar PV company, and a BER assessment may be required before and after the work. Grant rates and eligibility rules can change, so the amount and approval are not guaranteed. Check the latest terms on the official SEAI website and confirm the position with a registered installer before starting work.
