Solar

We believe every business should have the option to install solar.

We're building a greener energy future

Our goal is that all regional businesses have access to solar by 2025, and we're working hard to make it happen.

Why are there solar constraints?

The microgrid that powers your town needs to be carefully managed to ensure an increase in rooftop solar doesn't impact the stability of the network.

That's why we've set a limit on how much solar is connected to the electricity network in each town - this is called hosting capacity. Hosting capacity is currently constrained in a few regional towns, which means some businesses have been unable to install and enjoy the benefits of solar energy.

The good news is - we're working on it. We're transforming the grids across regional WA into renewable ready energy systems, so no one misses out on the opportunity to install solar.

Why are there solar constraints?

Are you solar ready?

Buyback for business

If you don't use all of the energy you generate, you could be eligible to sell your excess power back to us. The rate differs for each town and is determined by our cost of electricity generation and distribution.

Buyback rates are reviewed annually and subject to change. Not all customers will be eligible for the buyback, so it’s important to check if you are eligible before you apply.

Choose a reputable solar installer

The Clean Energy Council (CEC) solar retailer program is designed to lift the minimum requirements and bring about a better standard of service within the solar industry. That's why it's important to choose a CEC accredited installer. Visit their website to locate an accredited installer in your area.

While we’re not allowed to recommend specific systems or installers, we can help point you in the right direction so you can make an informed decision.

  • Broome solar hosting capacity release - March 2022

    Our new Community Battery arrived in March, enabling the release of more hosting capacity to Broome residents and businesses.

    Hosting capacity has since been exhausted in Broome and applications are now closed.

    Business customers
    This release focused on Broome businesses - with an allocation of 1100 kW of capacity.

    Residential customers
    Following on from the 900 kW allocated last July for households, an additional 300 kW of solar hosting capacity was allocated for residential customers after the Broome Community Battery is operational.

    The Community Battery has enabled us to allocate double the capacity to residential customers than originally planned for. Adhering to our 'first come, first served' principal - this capacity will be fully allocated to customers who submitted an application last July and were unsuccessful at that time. This means we were unable to accept new residential solar applications for this release.

    We're working on expanding our fleet of Community Batteries in Broome as quickly as possible. This will enable us to offer a lot more solar hosting capacity for Broome businesses and households at the end of the year.

  • When can I access solar in my town?

    Stay tuned!

    We are committed to increasing cleaner, greener renewable energy solutions to provide more choice and flexibility for households and businesses. As we get closer to opening up more hosting capacity in each town, we'll release more information.

    You can also sign up using our online form to be notified when solar becomes available.

  • How will you make access to solar more equitable?

    We offering a 50/50 allocation of available solar hosting between residential and commercial customers. 

    This will ensure distribution is more equitable and accessible to more of our customers.

  • Is there a waitlist?

    No. Due to the high demand of rooftop solar we process applications on a first come, first serve basis. However, you can sign up using our online form to be notified of any changes to solar capacity, products and trials in your area.
