Solar and Perth renters: what tenants can and can't do

Perth renters are affected by rising electricity costs as much as homeowners — but the path to solar savings is narrower when you don't own the property. The good news is that renters have more options than most realise, and WA tenancy law has been evolving to provide stronger tenant rights around energy efficiency.

What WA tenancy law says about solar

Under the Residential Tenancies Act 1987 (WA), tenants can make minor modifications to rental properties without landlord consent for specific categories. Rooftop solar installation is not in the minor modifications category — it's a structural change that requires:

1. Written landlord consent
2. In most cases, council approval (for structural modifications)
3. Western Power NCN approval (for grid connection)
4. CEC-accredited installation

A landlord can refuse consent to rooftop solar installation without being required to give a reason. Unlike some other states (Victoria, for instance, has proposed stronger tenant solar access rights), WA does not currently require landlords to approve solar installation requests.

What this means practically: If your landlord says no to rooftop solar, you have no legal avenue to compel them. Your options are to negotiate, make a business case, or choose a different approach.

Making the landlord case

Landlords who say no to solar often do so reflexively — they haven't considered it carefully. A well-prepared tenant request that addresses common landlord concerns is more likely to succeed:

Address the concerns landlords typically have:

• "What happens to the system when you leave?" The system adds value to the property. You can offer to leave it (with appropriate compensation at end of tenancy) or you can agree to remove it and restore the roof to its prior condition.
• "Who is liable if something goes wrong?" A CEC-accredited installation with proper NCN approval carries product and workmanship warranties. Propose to use a reputable Perth installer and provide all warranty documentation to the landlord.
• "What if it damages the roof?" Modern clip-on racking systems (particularly for Colorbond roofs) often don't penetrate the roofing material at all. Propose a racking system appropriate to the roof type.
• "What about the Western Power process?" Offer to handle all NCN application paperwork and keep the landlord informed throughout.

What you can offer:

• Nominal rent reduction period during installation inconvenience
• Agreement that the system stays with the property at your departure
• Right of first refusal for the landlord to purchase the system at market value when you leave

Some Perth landlords have agreed to solar installation on the basis that it increases property value and makes the property more attractive to future tenants.

Portable and ground-mounted solar: no permission required

Rooftop-mounted, grid-tied solar requires landlord consent. But several solar configurations don't:

Plug-in solar panels: Portable panels (often sold as "balcony solar" or "plug-in solar") connect to a standard power point and feed power directly into the household circuit. These are:

• Under 600W (single-phase safe) or configured for standard outlet connection
• Portable and removed when you leave
• Technically legal under current WA rules (the relevant regulations don't prohibit plug-in solar)

Caution: plug-in solar bypasses the grid-tied inverter and occupancy metering in ways that aren't fully regulated in Australia yet. Energy Safe WA hasn't specifically approved or prohibited them — check current rules before purchasing. Typical plug-in systems (200–600W) provide modest generation: 100–300 kWh/year in Perth. They won't transform your electricity bill, but they meaningfully offset daytime consumption.

Ground-mounted portable systems: A free-standing solar panel array in a backyard or courtyard connected to a portable battery (e.g., a Jackery, EcoFlow, or Bluetti powerstation) requires no council approval, no NCN, and no landlord consent. The entire system is moveable when you leave.

This approach is most effective for:

• Charging devices, small appliances, and laptops
• Running fans and small loads during the day
• Providing modest backup power during outages

Portable battery systems for renters

Standalone battery systems (without grid connection) are available and completely renter-friendly:

Entry-level portable powerstations (200Wh–500Wh, $300–$700): Charge from the wall during off-peak hours, discharge to run small loads when electricity is most expensive. Limited capacity — suitable for laptop, phone, fan, and lighting.

Mid-range portable powerstations (500Wh–2kWh, $700–$2,000): Meaningful battery capacity. Combine with portable solar panels for genuine solar + battery capability. Brands like EcoFlow, Jackery, and Bluetti are available in Perth.

Household-scale portable batteries (~5–10kWh, $4,000–$8,000): Some systems (e.g., EcoFlow DELTA Pro) provide near-residential battery storage capacity in a portable form. These can be charged from household power during off-peak hours and discharged in the evening — a form of time-shifting that reduces peak consumption cost.

These systems are fully removable, don't require Western Power approval, and don't need CEC installation. The tradeoff is efficiency — charging from the wall and discharging later has conversion losses, and you're not generating your own power (unless paired with portable panels).

Negotiating with your landlord as part of a lease renewal

The most successful time to raise the solar conversation with a landlord is during lease renewal. A landlord who is about to re-sign you (and values the stability) may be more receptive to a modification request than one in the middle of a fixed term.

Frame it as a property improvement: "I'd like to stay long-term and would like to improve the property with solar — at my own cost, with the system staying when I leave. Can we discuss this?"

Put it in writing: Any landlord consent to solar installation should be in a written addendum to the lease — specifying the system to be installed, the installer, and what happens to the system at end of tenancy.

Choosing a new rental property with solar already installed

The most straightforward way for Perth renters to benefit from solar is to choose a property that already has it. Before signing a lease on a solar-equipped property:

• Confirm the solar is operational and the inverter is working
• Ask if DEBS is registered and active (a solar property with an unconfigured DEBS arrangement means the export credits go to waste)
• Ask if the electricity bills from the past 12 months are available — this shows real-world savings, not hypothetical ones

Perth renters can't install rooftop solar without landlord consent, but portable solar panels, ground-mounted systems paired with portable batteries, and careful landlord negotiation all offer genuine pathways to reducing electricity costs. Choosing a property that already has solar is the simplest route. When negotiating for solar installation, framing it as a property improvement (with the system remaining at departure) often addresses landlords' key concerns.
