Can renters in Perth use a portable battery or solar? Options for tenants
Perth renters can't install rooftop solar without landlord permission, but portable power stations, plug-in solar kits, and tariff switching are options available to renters. Here's what's practical and what the law says in WA.

Approximately 30% of Perth households rent. For renters, the most impactful options for reducing electricity bills — rooftop solar and battery storage — require landlord approval and permanent installation. But there are meaningful options available to renters without any structural changes.
The WA tenancy framework for energy upgrades
Under the WA Residential Tenancies Act, tenants can make modifications to a rental property with written landlord consent. Landlords must not unreasonably withhold consent for modifications that improve energy efficiency under WA's minimum rental standards framework (which came into effect in phases from 2021–2023).
However, in practice:
- Most Perth landlords will consent to solar if the cost is borne by the tenant and the installation is professional (CEC-accredited)
- Some landlords are receptive to battery storage if installed by an approved contractor
- A landlord cannot charge the tenant for the system that was tenant-funded after the tenancy ends (generally), but removal and reinstatement costs are complex
If you want rooftop solar as a renter: Ask your landlord in writing. Frame it as an improvement to the property that benefits future tenants and may reduce wear on appliances (more consistent power quality). Offer to use a CEC-accredited installer and provide the Certificate of Compliance. Many WA landlords are open to this, particularly long-term tenancies.
For shorter tenancies or landlords who decline: The options below don't require structural installation.
Option 1: Switch to Midday Saver tariff
Eligibility: Any Synergy residential customer, including renters. Requires a smart meter (if you don't have one, Synergy installs it free).
What you don't need: Solar, battery, or any installation.
Benefit: If you work from home, can run appliances during 9am–3pm, or have timeable loads (pool pump, dishwasher, washing machine), Midday Saver's 8.85c/kWh super off-peak rate (vs 33.26c/kWh on A1) can reduce bills meaningfully.
For a renter working from home: Shifting lunch cooking, washing, and the dishwasher to 9am–3pm at 8.85c/kWh vs 33.26c/kWh saves approximately 73% on those loads.
Option 2: Portable power stations
Portable battery power stations (sometimes called "portable power banks" in the large format) — brands like EcoFlow, Jackery, Bluetti, Anker SOLIX — are freestanding units that don't require installation. They can:
- Be charged from a standard 240V power outlet
- Power devices and appliances that run on 240V
- Be charged from optional portable solar panels (plug-in, not roof-mounted)
Practical limitations for Perth renters:
- Capacity: 1–5kWh (small compared to a 10kWh home battery)
- Cost per kWh storage: $400–$1,200/kWh (much higher than installed home batteries)
- Charging from the grid: at A1 (33.26c/kWh), charging the battery costs roughly the same as grid power — there's minimal saving unless paired with cheap tariff windows
Best use cases:
- Power outage backup (camping, work tools, medical devices)
- Off-grid camping and travel
- Charging at Midday Saver super off-peak (8.85c/kWh) for use in peak (55.33c/kWh) evening — marginal arbitrage for small loads
Not suitable for:
- Powering high-draw appliances (AC, oven, hot water) for extended periods
- Replacing a home battery installation as a cost-reduction measure
Option 3: Plug-in solar panels
Plug-in balcony solar panels ("Balkonkraftwerk" in Europe, "plug-in solar" in Australia) are portable solar panels with a micro-inverter that connects to a standard power outlet. They generate electricity into the home's circuit without permanent installation.
Status in Australia: Plug-in solar is technically possible in Australia but the regulatory environment is complex. Australian standards (AS/NZS 4777) technically require grid-connected solar systems to be installed and commissioned by a CEC-accredited electrician and approved by the network operator (Western Power). A plug-in unit that feeds into household wiring may not comply with this framework without Western Power approval.
Practical situation in Perth (2026): Plug-in solar is a grey area in Australian regulations. Some products are sold for camping or off-grid use. Large-scale balcony solar (as seen in Germany, where it's regulated and widely used) doesn't have a clear regulatory pathway in WA. This may change as the technology becomes more common.
If you're considering it: The regulatory position should be confirmed before purchase. Contact Western Power and Synergy to understand current requirements. Without clarity, there's a risk of a non-compliant grid connection.
Option 4: Negotiate a solar clause in your lease
For renters with longer tenancies (2+ years), negotiate a lease clause that allows solar installation at tenant cost, with an agreed process for removal or handover at tenancy end. Some landlords are open to covering the system cost in exchange for rent stability or a lease extension.
The most tenant-favourable outcome is a landlord who covers the installation cost and passes the savings to the tenant through reduced rent or a fixed contribution — treating the solar as a property upgrade.
What makes the biggest difference for Perth renters
In order of impact:
-
Tariff switch to Midday Saver (free, immediate): works for any renter with timeable loads during the day. No installations needed.
-
Energy-efficient appliances and behaviour: LED lighting, WELS-rated showerheads, keeping fridges full (less cycling), heavy winter blankets reducing heating. Small individually, meaningful in aggregate.
-
Air conditioning efficiency: Use ceiling fans to distribute cooled air and set AC to 24–26°C (every degree cooler costs ~10% more electricity). Pre-cool the house before peak (3pm–9pm on Midday Saver) using the 8.85c/kWh rate.
-
Negotiate solar installation with landlord: The biggest single improvement, requires landlord cooperation.
-
Portable battery as backup/camping (not as a cost-reduction measure): meaningful for specific use cases.
Renters can still meaningfully reduce electricity costs through tariff optimisation and behaviour shifts. Upload your Synergy bill to BillWise to identify which changes would save the most for your specific usage pattern.
