Solar panels - non domestic

Planning Permission: Solar panels mounted on a non-domestic building

All the following conditions must be observed:

  • Equipment should be sited, so far as is practicable, to minimise the effect on the external appearance of the building and the amenity of the area.
  • When no longer needed the equipment should be removed as soon as reasonably practicable.

All the following limits must be met:

  • Solar panels installed on a wall or a pitched roof should project no more than 200mm from the wall surface or roof slope.
  • Where panels are installed on a flat roof the highest part of the equipment should not be more than one metre above the highest part of the roof (excluding the chimney).
  • Equipment mounted on a roof must not be within one metre of the external edge of that roof.
  • Equipment mounted on a wall must not be within one metre of a junction of that wall with another wall or with the roof of the building.
  • The panels must not be installed on a listed building or on a building that is within the grounds of a listed building, or on a site designated as a scheduled monument.
  • If the building is on Article 2(3) designated land* the equipment must not be installed on a wall or a roof slope which fronts a highway.
  • If the equipment is on the roof of the building the capacity for generation of electricity across the whole of the site cannot exceed 1 megawatt.
  • Other than microgeneration solar thermal equipment or microgeneration solar PV equipment, if there is to be any other solar PV equipment installed on the roof of a building then the Prior Approval (56 days) of the Local Planning Authority is required. This will assess the design and external appearance of the development, particularly in respect of the impact of glare on occupiers of neighbouring land.
