The cost after the SEAI solar PV grant depends on the system size, property and installer’s quotation, so there is no single final price. Apply online through the SEAI before any installation work begins, then choose an SEAI-registered solar PV company to assess your home and complete the installation. The installer normally helps with the required documents, while SEAI decides whether the application meets the scheme’s conditions. Check the current grant limits and application process on the official SEAI website, as terms can change.
