The installation of solar panels on residential buildings are considered permitted development so you do not require planning permission if they comply with the following conditions. There are necessary limits and conditions which must be complied with to benefit from permitted development rights. Solar panels should not be installed above the highest part of the roof and should not project more than 200mm from the roof slope or wall surface. Installers should not install solar panels on a building that is within the grounds of a listed building or on a site designated as a scheduled monument. If your property is in a conservation area, or a World Heritage Site, you must not install solar panels on a wall that faces a highway.
