Apply to connect
Before you purchase a solar or battery system, you need to apply for approval to connect to the network. Here’s an overview of the process:
Check your town
Before you start, use the calculator to see if you are eligible to install solar in your town.
You can also find out about any buyback offers available and your estimated yearly savings with solar.
Speak to your installer
If you've chosen an installer and solar system, it's time to apply online.
Your installer will most likely do this for you because of the technical information you need to provide with your application.
Approval to connect
We'll review your application and check it meets our technical requirements to connect to the network.
We will notify both you and your installer in writing, usually within 10 business days.
We will never ask you for a deposit to ‘secure your place’ on a solar application list. Please confirm your installer is CEC accredited and there's solar capacity in your town, before paying a deposit or the total costs upfront. If you’re ever in doubt, please call us on 1800 267 926.
Apply for buyback on an existing system
If you have just moved into your home and already have solar installed, you may be eligible for a renewable energy buyback offer.

Need to knows
Speak with your installer about fees and charges
There are no fees to apply to connect your solar system to our network.
For systems greater than 5kW, there are times that we need to carry out further technical assessments to ensure connecting your system won't impact the stability of the network. There are fees associated with these assessments, and you should discuss these fees with your installer.
In some cases, it will take longer than 10 days to process your application
After we receive your application, we'll undertake an assessment to make sure it meets our technical requirements. In most cases, this will take 10 business days.
For systems larger than 5kW, further technical assessments may be required and can take up to an additional 30-90 days, depending on the system size and location.
We may require additional information throughout this time, and we'll keep you and your installer informed along the way. It's a good idea to discuss this process with your installer so you know what to expect upfront.
We're also here to answer any questions you may have. Call us between 8 am - 5 pm weekdays on 1800 267 926.
After receiving approval, you have three months to install your system
Once you receive written approval from us to connect your system to our network, you can go ahead with installing your solar system.
It's important that your system is installed, and we receive the necessary preliminary and completion notice from your contractor, within three months of your application being approved. Otherwise, your approval to connect will lapse and you must reapply.
If you're making changes to an existing system, we need to know
If you already have solar installed, there are times you may need to make changes. This could include replacing faulty or aged equipment, or increasing the size of your system to better suit your energy needs.
If this is the case, it's important to let us know, so we can ensure these changes meet our technical requirements to connect to the network. You'll need to submit an application form for assessement and we recommend discussing this with your contractor.
If you have moved into a home that already has solar installed, you may be eligible for a buyback offer. Please call us on 1800 267 926 to discuss your eligibility and the buyback rates available.
