Solar power systems are much simpler to install than other generation systems, but don’t forget they are subject to legal requirements. In the specific case of New South Wales, a solar installation may need individual permission based on its installed capacity in kilowatts and also the conditions of the property where it will be deployed. This article provides an overview of the general guidelines, but remember there are specific rules for each council.
The best way to ensure your solar power system meets Australian building codes and local legislation is working with a qualified and experienced provider. In addition to bringing technical expertise to the project, they are already familiarised with the regulatory framework.
Do not confuse council permitting with the network interconnection procedure, which applies for all grid-tied solar power systems. Just like permitting requirements change by council, interconnection requirements change by network provider.
Assuming no additional conditions apply, the main factor that determines the permitting procedure for a solar power system is the installed capacity in kilowatts.
With a detailed assessment of your electricity consumption profile, you can determine the optimal solar system capacity for your property. Oversized installations are not recommended, since you will get a diminished financial performance; all surplus production is exported to the power network, and you get a feed-in tariff that is only a small fraction of the retail kWh price.
Even if your solar PV system would qualify as exempt development or complying development, there are special cases where an individual permitting procedure is required:
If you are considering solar power for a property in New South Wales, make sure you follow the correct permitting procedure to avoid legal hassles later on. The best recommendation is working with an experienced solar PV system provider.
