The new arrangements are not in place yet.
The WA Government is currently consulting on the safety, technical and regulatory requirements that would need to be met before plug-in solar and batteries can be legally used.
Public consultation is underway on the proposed legalisation pathway and technical standards.
Feedback closes 5 pm, 9 December 2026.
After consultation, the WA Government intends to consider feedback and develop an updated certification route and Technical Bridging Standard. Subject to that consultation and further technical work, the consultation paper anticipates this work being completed by February 2027, after which regulatory changes would be prepared.
Following consultation, we’ll keep customers updated as the final requirements and next steps are confirmed.
Frequently asked questions
Plug-in solar is a small solar generation system designed to connect to a home's electricity supply through a standard wall socket. Some products can also include battery storage.
“Balcony solar” is a commonly used name because some systems can be mounted on balconies. The proposed requirements allow plug-in solar to be installed in different ways, including on balconies, walls, fences or on the ground.
No, right now plug-in solar systems cannot be legally connected and used in WA. The WA Government is currently consulting on the pathway to legalise these systems.
You may see plug-in solar and batteries advertised online, but we recommend waiting until the WA requirements are finalised before buying one. Being available to buy does not mean a product is approved or legal to use in WA.
The rules and technical requirements are still being developed. A system purchased now may not meet the final requirements or be suitable for Horizon Power’s electricity systems. This could affect how well the system performs and the savings you receive.
Once the requirements are finalised, customers will have clearer information about products and the appropriate settings for use on Horizon Power’s network.
Safety is a key part of the WA Government consultation. The proposed requirements are being developed to make sure plug-in solar and batteries can be safely used in Western Australian conditions. Until those requirements are finalised, don't connect a plug in solar or battery system to your home, even if you can purchase one online.
Don't connect or use it yet. Plug in solar and battery systems cannot currently be legally connected and used in WA. The final requirements are still being developed, and a product purchased now may not meet them. We'll provide more information for Horizon Power customers once the requirements are finalised.
The WA Government consultation closes on 9 December 2026. The proposed requirements may change as a result of consultation. Horizon Power will update this page as more information becomes available and provide customers with clear information about what they need to do once the requirements are finalised.
