As of 2026, rooftop solar PV on a typical Irish home will generally be exempt from planning permission where the relevant conditions are met. These conditions can cover the panels’ height, position and potential effects such as glare, while protected structures or other site-specific planning restrictions may require extra checks. Planning permission and SEAI solar PV grant eligibility are separate matters, and neither should be assumed without confirming your circumstances. Check with your local authority or a registered installer before proceeding, and consult the official planning guidance for the current rules.
