What Are The Necessary Permits in Australia For Solar Panel Installation And How Long Do They Take To Obtain?

The requirements of any solar panel permits in Australia depend on both location and the situation. Most residential solar installations are either considered exempt development or complying development (meaning there is typically no need for a DA to your local council).

This varies on local council requirements, especially if the property is located in a heritage conservation area or where special circumstances apply such as those being visible from public spaces or major roads. If the property falls in any such categories, it might also need a planning permit. Moreover, all solar installations must meet federal building codes and standards for structural, electrical, fire protection among others.

All grid-connected systems need to be approved by your local electricity distributor, and all electrical work must be completed by an appropriately licensed electrician. Some areas may ask for more; e.g. in Queensland many solar installations can be classified as self-assessable work, which means you wouldn’t need a building certifier to part of the construction development application (CDA) process although they would still have to meet all applicable building codes and standards.
