If you’re thinking about installing solar panels, one of the first questions you might have is whether you need planning permission. It’s a smart thing to check early, because the rules can depend on your roof type, where you live, and how your home looks from the street.
The good news is that most solar panel installations in Ireland are exempt from planning permission, meaning homeowners can often install solar without making a formal application. You do not need planning permission to install solar panels to the roof of your property. You can also install freestanding solar panels as long as you meet certain conditions.

A good installer will design the system to be safe, stable, and visually appropriate.
Planning permission is only one part of the picture.
Even when planning permission is not required, your solar installation must still be:
