Energy and Decarbonisation Minister Amber-Jade Sanderson and Commerce Minister Dr Tony Buti have announced that the WA Government intends to legalise plug-in solar and battery systems.
Legalising plug-in solar and battery systems will create a new route for households to cut energy bills using their own renewable energy.
The Departments of Energy and Economic Diversification (DEED) and Local Government, Industry Regulation and Safety (LGIRS) are now consulting on a proposed pathway to give consumers safe and legal access to the systems, often known as ‘balcony solar.’
The proposal aims to overcome regulatory and technical barriers through a targeted regulatory amendment and a new technical standard that would allow:
- Solar panel combinations up to 2 kilowatts (DC)
- Inverter units up to 800 watts (AC)
The proposed standard is modelled on the existing German technical standard for plug-in solar systems, but with additions to also allow battery storage. The standard would not set an upper limit on storage capacity.

Stakeholders are invited to provide feedback before 5:00pm (AWST) on 9 December 2026.
