For the SEAI solar PV grant, the home will generally need to meet conditions such as having a valid electricity meter point reference number (MPRN) and being built and occupied before the relevant eligibility date. You normally need to apply before work starts and use an SEAI-registered contractor, with required BER and installation paperwork completed. Previous grant support for solar PV at the property may also affect eligibility. SEAI makes the final decision, so check its current guidance and confirm the details with your registered installer before proceeding.
