After a bushfire, treat every part of your solar and battery system as live and potentially dangerous. This guide explains safe first steps, what a professional inspection covers, records for insurance and why ash cleaning must wait. After a bushfire, treat your whole solar and battery system as live and potentially dangerous, even if the grid is down and the main switch is off. Panels produce DC electricity whenever light reaches them, heat can destroy cable insulation without obvious signs, and a fire-affected battery can release toxic gases or reignite hours or days later. Return only when emergency services say it is safe, look from a distance first, isolate the system only if you can do so safely using the installer's shutdown procedure, and have a licensed electrician or accredited installer inspect everything before it is used again. Record the damage carefully for insurance.
Why fire-affected systems stay dangerous
- Panels never switch off in daylight. Turning off the inverter or main switch stops the AC side, but the DC cables between the panels and the inverter can still carry hazardous voltage.
- Heat damage is often hidden. Cable insulation, connectors and isolators can soften or crack from radiant heat, leaving exposed conductors or earth faults that cannot be seen from the ground.
- Batteries can fail late. Heat can damage cells internally. Swelling, hissing, smoke, unusual smells or heat from the casing mean the battery must be left alone.
- Structures may be weakened. Roof sheets, battens, mounting rails and ground-mount frames can be damaged, so panels may be less secure than they look.
- Fuel and gas are nearby. Generators, fuel tanks and gas bottles close to equipment add further risk.
A safe order of first steps
- Wait for the all-clear from emergency services before returning to the property.
- Keep children, pets and stock away from panels, cables, the battery room and fallen wires.
- Look from a distance. Do not climb onto roofs, enter a damaged plant room or open any enclosure.
- If a battery is smoking, hissing, swollen or hot, keep well away and contact emergency services.
- If the equipment appears undamaged and the shutdown procedure is displayed at the switchboard or inverter, follow it only if you can reach the switches safely without touching damaged components.
- Do not reset protection devices or restart the inverter or generator.
- On a grid-connected property, do not try to reconnect or restore supply yourself.
- Contact your installer or a licensed electrician, and notify your insurer.
If the property relies on a battery for essential circuits, the battery backup guide explains how those circuits are usually separated, which helps when you describe the setup to the electrician.
What a professional inspection covers
A fire-affected system needs testing, not just a visual check. A typical inspection looks at:
| Component | What is checked | Possible outcome |
|---|---|---|
| Panels | Cracked or discoloured glass, heat-affected backsheets and frames | Return to service after cleaning, or replace affected panels |
| Mounting and roof | Rails, clamps, fixings, roof sheets and ground-mount frames | Repairs, or removal before roof or structural work |
| DC cabling and isolators | Insulation resistance, connectors, conduit and enclosures | Replacement of heat-affected cables and components |
| Inverter | Heat and smoke exposure, fault history, internal condition | Testing, repair under manufacturer guidance, or replacement |
| Battery | Casing, event logs, manufacturer's post-fire requirements | May need replacement after significant heat exposure, even without visible damage |
| Switchboard, earthing and generator changeover | Protection devices, earth connections, changeover wiring | Repairs before anything is re-energised |
An Electrical Safety Inspection is listed on the energy market at $299 for a solar system and switchboard, and Solar Repairs from $299 per repair visit. After a fire the scope is often larger than a routine inspection, so treat these prices as indicative and confirmed after a site assessment.
Keeping records for insurance
Good records make claims simpler and help installers source matching replacement parts.
- Photos and video of all equipment, taken from a safe distance, with dates.
- Installation paperwork, including panel, inverter and battery models and serial numbers.
- Invoices and warranty documents.
- Monitoring data showing performance before and after the fire, if it is still accessible.
- The electrician's or installer's written inspection report.
Do not dispose of damaged equipment until your insurer agrees, but do not keep damaged batteries in or near the house either. Removal, transport and disposal of fire-affected batteries is a job for specialists.
Ash, residue and cleaning
Ash and smoke residue on panels reduce output, and ash mixed with water can form a corrosive, alkaline slurry. The temptation is to hose everything off as soon as you are back, but cleaning must wait until the system has been inspected and made safe. Hosing live, heat-damaged equipment is dangerous, and walking on fire-affected roofs is a serious fall risk. When cleaning is cleared, use a professional cleaner with soft, water-based methods, because high-pressure washers and harsh chemicals can damage panels and seals. If you collect rainwater from the roof, ask the cleaner or a plumber to divert downpipes first so residue does not wash into your tanks. Ground-mounted arrays are easier to reach, but the same rule applies: no cleaning until a licensed electrician or accredited installer has confirmed the array and its cabling are safe.
Getting essential power back
If the solar system is out of action, a portable generator may be the short-term answer, but only connect it through a changeover switch or generator inlet installed by a licensed electrician, never by back-feeding a power point. Before any temporary supply is connected, the electrician should confirm that the damaged solar system and battery are isolated, so the generator cannot energise faulty cabling. Prioritise water pumps, refrigeration and communications, since these matter most while you assess the rest of the property. The generator and battery comparison is useful when you plan how a rebuilt system should handle future outages. A rebuild is also a chance to reconsider equipment locations, clearances and fire separation, and properties in high-risk areas such as the Blue Mountains benefit most from that review.
Next steps
Once the property is safe to access, request a free assessment from Blue Energy Solar. An inspection on site can confirm what is safe, what needs repair or replacement and what documentation your insurer is likely to ask for, and any replacement system can be designed with better fire resilience. The installation and any grid-connection application for a replacement system are handled for you.
Frequently asked questions
My panels look undamaged. Do I still need an inspection?
Yes. Radiant heat and smoke can damage cable insulation, connectors, isolators and inverter electronics without any visible change to the panels themselves. Batteries can also suffer internal damage that only shows up later. Electrical testing identifies hidden faults before the system is re-energised, and a written report from a licensed electrician also supports any insurance claim you make.
Can a fire-affected battery be repaired?
That decision belongs to the manufacturer and a qualified installer, based on the battery's exposure, its event logs and the manufacturer's guidance. Owners should never open, move or try to restart a battery that has been near a fire. If replacement is recommended, removal and transport need to be handled by people trained to manage damaged lithium batteries safely.
Will a replacement system attract current incentives?
A new installation may be eligible for STC discounts on solar and, where a battery is installed with solar, the federal Cheaper Home Batteries Program, subject to the usual conditions. Values step down on set dates, so they may be lower than when the original system went in. Confirm current values on the Clean Energy Regulator's pages and discuss eligibility with your installer before signing.
