Installing solar panels

In Mosman, the installation of solar panels or photovoltaic cells for generating electricity and heating water is classified as ‘Exempt Development’ and in most cases does not require Council approval provided that certain basic requirements are met. These requirements are fully detailed in Clauses 20(2) and 39 of State Environmental Planning Policy (Infrastructure) 2007.

A summary of the ‘Exempt Development’ requirements for installing solar panels is provided below:

1. The system is integrated into the building or is flush or parallel with the surface of its roof; and
2. The development does not reduce the structural integrity of, or involve structural alterations to the building; and
3. The development does not necessitate the removal of trees from near the building to ensure that solar energy is available for the system; and
4. On average, over any 5 year period, at least 75 per cent of the electricity generated by the system in a 12 month period is used in or for the building; and
5. The system is not located on a building that is a State or local heritage item or is in a heritage conservation area.

Further advice can be obtained from Council’s Development Advisor who is available for public consultation between the hours of 8.30am – 10.30am, Monday to Friday or by phone – 9978 4172.
