Donnybrook properties range from town homes to lifestyle blocks and productive acreage. A house may have grid-connected solar, a battery, a hybrid inverter or a stand-alone supply; the orchard pumps may run on an entirely separate meter or power arrangement. The word “solar” is therefore too broad for a buyer handover. Before launch, map the actual equipment and its relationship to the dwelling being sold.
This guide is general sale-preparation information, not electrical, legal, energy-market or valuation advice. Use a licensed electrical contractor for system condition or compliance questions, the retailer and network operator for account arrangements, and the settlement professional for contract wording. Do not assume that an attractive generation graph proves a future buyer's bills or export payments.
Start with an equipment and ownership schedule
List the panel brand and rated capacity, inverter model and serial number, battery model and usable capacity where documented, installation dates, monitoring access and any later upgrades. Identify the main switchboard and any separate supply to sheds, irrigation pumps, cold rooms or workshops. The buyer should not discover after settlement that a photographed array serves a different meter or that a shed system was excluded.
Check whether the equipment is owned outright, financed, leased or part of another arrangement. Keep the contract and payout information private until the agent or settlement professional has explained how the interest should be handled. If a battery was installed under a scheme, review the relevant terms rather than assuming the rebate or loan follows the address automatically. The WA Residential Battery Scheme publishes detailed eligibility and account requirements; a property listing should not promise a successor eligibility result.
Record what remains with the property and what does not: panels, battery, inverter, monitoring gateway, wall charger, portable generator or spare components. Put unusual exclusions in writing early. A photograph can suggest an item is included even when the seller intended to move it.
Collect the electrical and warranty file
Consumer Protection advises people buying a home with solar panels to seek the seller's warranty and approval paperwork. Gather installer invoices, equipment manuals, warranty certificates, network approval, electrical safety certificate, notice of completion, service records and any fault or replacement history. Match each document to the model actually on site. An old quote for equipment that was never installed is not proof of the current system.
Ask the installer or a licensed contractor which warranties can be transferred, which require registration and which may have expired. A panel performance warranty is not the same as a workmanship promise, inverter warranty or battery capacity guarantee. Do not say “under warranty” without confirming the relevant component, term and claimant. Supply the buyer with the process and contact details that are still current.
For a newer battery, include commissioning information, shutdown instructions, emergency labels and the location of the equipment. WA Building and Energy explains that solar PV and battery work is generally electrical installing work and provides specific battery safety guidance for licence holders. A seller should not open covers or test wiring to make a marketing video.

Understand the 2026 rules without making the wrong claim
Energy Policy WA says new requirements took effect on 1 May 2026 for new and upgraded small-scale solar and battery installations in the South West Interconnected System. The published rules cover matters including inverter capacity and emergency solar management or export limits. The government also distinguishes existing systems that were commissioned before that date from systems newly installed or upgraded after it.
That distinction matters in a sale. A system installed years ago is not automatically “non-compliant” because a new installation rule exists, and an owner cannot assume a future buyer's planned battery upgrade will use the old connection settings unchanged. If the equipment has been upgraded or the seller cannot identify the commissioning date, obtain a licensed installer's advice and current network records before describing its status.
Do not advertise a battery as eligible for a rebate, able to export at a particular rate or ready for a virtual power plant without checking the current property, product and account terms. Tariffs and retailer offers belong to a particular period and account. Give buyers official source links and let them confirm their own eligibility.

Describe output and bills with evidence
Provide a dated sample of generation data if the monitoring system can export it, and explain whether it measures panel output, household consumption, battery charge or grid export. A screenshot without the meter definition can be misleading. Keep account numbers and personal details out of public documents. Historic bills may help a buyer understand the previous household's use, but they do not predict a different family's consumption, future tariffs or seasonal weather.
Ask the owner to note major changes during the sample period: a vacant house, new air conditioner, irrigation pump, changed battery settings or extended travel. If a rural property has separate meters, identify which bill corresponds to the dwelling and which to the business. Never add farm equipment savings to a residential claim unless the circuits and invoices support it.
For pricing, REIWA's Donnybrook annual house median was $760,000 for settled sales through September 2026, updated 15 October 2026. That is a suburb statistic, not a valuation of a particular house or the value of its solar system. Ask a licensed agent to compare genuinely similar local sales and explain how buyers may treat the verified equipment, condition and ownership.

Photograph the installation safely and accurately
A useful gallery can show the roof array from safe ground level, the battery's relationship to the dwelling, the inverter location and a clear image of the main living areas. Do not climb onto a roof, open electrical equipment or move safety signage for a better image. WA Building and Energy says roof and ceiling areas near solar cables present serious electrical risks and recommends leaving system maintenance to electricians and installers.
Use a brief video to explain what is included and where it is located, not to demonstrate risky switching or promise a bill outcome. Keep labels readable but redact serial numbers if publishing them would create a security concern. If a battery is pictured, confirm it is actually included in the sale and that the owner has permission to show monitoring data.
Prepare the handover before the offer
Put the equipment schedule and documents in a buyer pack. Ask the agent and settlement professional to confirm the inclusions wording, any finance or lease issue, and how monitoring credentials will be transferred securely. Plan a final demonstration with the installer if the controls are complex. Reset personal accounts only after the buyer has the information needed for lawful, safe operation.
For acreage, keep household solar records separate from the dam, bore and water-licence records and the orchard equipment schedule. A buyer needs to see which assets, meters and operating costs relate to the home and which relate to production. This separation also helps prevent a broad “self-sufficient” claim that the evidence cannot support.
