Solar PV panels on homes are generally exempt from planning permission in Ireland when they meet the conditions in the planning regulations, but the exemption is not unlimited in every situation. Requirements can cover the panel position, projection from the roof or wall, visual impact and the type of property involved. Planning permission or additional checks may be needed for protected structures, properties in architectural conservation areas or installations that do not meet the exemption conditions. Ask your local authority planning section or a qualified installer to confirm the position for your home, and check current SEAI guidance separately because grant eligibility is a different matter.
