Western Power is responsible for approving the connection of new solar PV systems to the South West Interconnected Network. A system can only be connected once all of the applicable connection eligibility criteria have been met.
Please refer to the 'Solar PV connection process' fact sheet for information on the solar PV connection process.
A solar PV (photovoltaic) system, the most common of the Inverter Energy Systems, converts solar energy into electricity.
When a solar PV system is connected, it has the potential to increase the amount of power flowing into the network.
To ensure power quality, reliability of supply and prevent a network capacity overload, Western Power must be advised of, and approve the connection of, all solar PV systems.
In some areas, the connection of new solar PV systems is subject to Western Power completing network upgrades or installing new infrastructure to ensure the network capacity is large enough to service community and business demand.
The approval process to connect your solar PV system to the network depends on the size of your system and the capacity of the network in the suburb or region where it will be installed.
To assist Western Power in approving applications within an acceptable time frame it is imperative that the embedded generation application forms are filled out correctly. To assist you with this, we have developed a new application form as an editable PDF that can be saved onto your desktop.
A copy of the new editable application form can be downloaded at http://www.westernpower.com.au/documents/ssres/Application_to_connect_embedded_generation_to_network_-_3072.pdf
Not only will this new form help you, by reducing the time taken to complete an application, it will assist us with the legibility and quality of information we receive.
The quality of your applications will now be assessed upon receipt by Western Power. If your application is filled out correctly it will be processed however, if there are problems with your application it will be rejected.

EnergySafety has issued a public warning about dangerous switches used in some solar systems installed since January 1, 2012. Click here to read the media statement.
Western Power would like to notify solar suppliers and installers of upcoming adjustments to the way applications for the connection of embedded generation systems less than (or equal to) 30 kVA are handled.
From 1 July 2013, the application process will follow a simple, mandatory three step process to getting a solar PV system connected:
Western Power has developed an industry fact sheet for those wishing to know more about the upcoming adjustments to the application process.
