Is it legal to install solar panels without a building permit in Sydney?

In Sydney, whether you need a building permit to install solar panels largely depends on the specific characteristics of the installation and the local council regulations. Generally, smaller solar panel systems that are installed on residential properties may not require a building permit if they meet certain criteria, such as being below a specific size and not affecting the structural integrity of the building. However, larger installations, or those on heritage-listed properties, often require a permit. It is essential to consult with the local council to understand the specific requirements, as they can vary significantly across different areas within Sydney.

Trivia: Australia is one of the world leaders in the use of solar energy per capita, largely due to its abundant sunshine and supportive government policies. In fact, on some days, solar power has been known to contribute up to 50% of the total electricity generation in some states.
