How plug-in solar works
Solar panels turn sunlight into direct-current electricity. Compatible equipment, typically an inverter, converts that energy into electricity suitable for household use. Some systems may also include battery storage to hold energy for later use.
‘Plug-in solar’ generally refers to compact equipment designed for simplified connection in markets where that arrangement is permitted. It does not mean that an overseas product is approved for use in Australia, or that any household connection is safe or lawful.
Output varies with sunlight, shading, orientation, weather and the equipment. This guide is a general explanation, not installation or electrical connection instructions.

The proposed WA pathway
On 27 October 2026, the WA Government announced its intention to legalise plug-in solar panels and batteries and launched consultation on a safety standard. That announcement is a policy direction, not current authorisation to connect a system.
The WA Government’s ‘Plug in to Power Up’ consultation explores a pathway for plug-in solar and batteries. Its consultation material includes frequently asked questions and a Draft Technical Bridging Standard.
The proposed approach would treat compliant plug-in systems as electrical appliances through a new technical bridging standard. The certification route and technical standard are still being developed; final regulatory changes would be needed to put the pathway in place.
Consultation documents describe proposals for consideration. A draft standard is not a final standard, and a proposed pathway does not itself authorise installation or connection. Do not treat proposed technical limits, equipment conditions or connection arrangements as confirmed requirements.
The official WA Government FAQ says plug-in solar and battery systems cannot be installed yet and that installation remains illegal while consultation is underway. Before considering a future system, check the latest official guidance and confirm the applicable regulations, product approvals and connection requirements for your property.

Could it suit your home?
A compact system may be worth exploring for a balcony, courtyard or other small outdoor area with useful sunlight. Being interested in a system is different from being approved to install or connect one.
Renters and apartment residents may need landlord, strata or building permissions. Available space, structural safety, electrical arrangements and household energy use all matter. A sunny balcony alone does not establish suitability.
- How much direct sunlight reaches the location, and what shades it during the day?
- Can equipment be securely supported without creating a falling-object, access or building-safety risk?
- Who owns or controls the space, and what permissions would be needed?
- When does your household use electricity, and would generation align with that use?
04
Practical considerations before any purchase
Do not buy or connect equipment on the assumption that proposed rules will be adopted unchanged. Seek appropriately qualified advice about electrical and structural suitability, and check with the relevant electricity network operator and property authority where needed.
- Product compliance: ask for evidence of applicable Australian approvals and standards for the complete system, not just individual parts.
- Connection: confirm the final process, any network conditions and whether professional electrical work is required. Do not improvise a connection or modify household wiring.
- Mounting and exposure: consider wind, weather, corrosion, access and safe maintenance at the intended location.
- Battery options: check compatibility, safe placement, ventilation and the requirements that apply to the specific equipment.
- Costs and value: assess any eventual quote, installation costs, warranty and support alongside your tariff and usage. No price, savings estimate or payback period is confirmed here.

What happens next?
We’re following regulatory developments and speaking with suppliers as the proposed WA pathway takes shape. These discussions do not mean supply arrangements or product approvals are confirmed.
For Plug into Solar, no product range, product approvals, prices, savings figures or availability date are confirmed. A proposal or consultation timetable is not a product launch date.
Future availability is subject to final regulations, product approvals, confirmed supply arrangements and suitability for the individual property. Joining our interest list does not guarantee availability or authorise installation or connection.
We are gathering expressions of interest only. We are not taking orders or payments.
- The final regulatory pathway and any commencement arrangements.
- The technical and connection conditions that would apply to a particular system and location.
- Which products, if any, will meet the final requirements and be supplied locally.
