For many standard homes in Ireland, rooftop solar panels may be exempt from planning permission if they meet limits on panel area, roof coverage and how far they project from the roof. Apartments, shared buildings and installations that exceed the exemption conditions may require permission or agreement from the management company, while protected structures and conservation areas can have additional restrictions. Ground-mounted systems and panels in prominent locations should also be checked with the local authority. Planning rules are separate from SEAI grant eligibility, so confirm the current requirements with your council, a registered installer or the official planning guidance.
