The Microgeneration Support Scheme (MSS) generally covers small renewable electricity systems, including solar PV, connected to the electricity grid, with eligibility depending on the system size and applicant’s circumstances. You will normally need an eligible property, an approved grid connection through ESB Networks and a registered electricity supplier to receive any Clean Export Guarantee payment for electricity sent to the grid. The SEAI solar PV grant is a separate support with its own conditions, including requirements around the property and installer. Check the latest guidance with SEAI, ESB Networks and your chosen registered installer, as they ultimately confirm the applicable requirements.
