What is Planning Permission?
Formal approval from your local authority to make changes to your property — not usually needed for residential solar.
Quick Answer
Most residential solar installations in Ireland are exempt from planning permission under the 2007 and 2022 regulations. The exemption applies if: panels do not project more than 15cm from the roof surface, the total area does not exceed 50m² (or 12m² for flats), and the building is not a protected structure. Ground-mounted systems up to 25m² are also exempt. If your home is a protected structure or in an architectural conservation area, you will need permission.
