Many domestic solar PV installations may be exempt from planning permission, provided they meet the relevant conditions, but this depends on the property and installation. If permission is required, your local authority may ask for an application form, site location and layout maps, roof plans or elevations, panel specifications, and details of possible glare or visual impacts. For an SEAI solar PV grant, a registered contractor normally manages the application and provides the required installation information; planning documents may be needed where permission applies. Check with your local authority and contractor before work begins.
