Solar, storms and insurance in Pakenham.
Most Cardinia Shire homeowners who put $20,000 of solar and battery on their house never told their insurer, and are now quietly underinsured by exactly that amount. Here is what is covered, what is not, and the sequence to follow the morning after a hailstorm.
Is your array actually insured?
In most cases yes, but as part of the building sum insured rather than as a separately listed item. Panels are a fixture, like a pergola or a hot water unit. They are not contents and they are not usually itemised, which is why so many people assume they are covered and never check.
That distinction matters more than people realise. If your building sum insured was set before you spent $8,000 on solar and another $12,000 on a battery, you are now underinsured by roughly that amount, and in a total loss the shortfall is yours. Worse, many policies apply an averaging or co-insurance clause where significant underinsurance reduces even a partial claim.
Most insurers also want to be told about a solar or battery install as a material change to the risk. The two-minute job after any install - and we say this to every customer at handover - is to phone your insurer, tell them what went on the roof and what is on the garage wall, and get the sum insured lifted. It is the cheapest thing you will ever do to protect a $20,000 asset, and almost nobody does it.
Worked example - the underinsurance gap.
A Heritage Springs homeowner insured the house at $520,000 building sum insured in 2023. In 2026 they add a 10kW array and a 13.5kWh battery:
- 10kW solar array, gross replacement cost: about $11,500
- 13.5kWh battery and hybrid inverter, gross replacement cost: about $16,000
- Scaffold, make-safe and re-commissioning in a rebuild: about $2,500
- Uninsured gap created: roughly $30,000
Note that the replacement figure is the gross cost, not the rebate-net price you paid. If the array is destroyed the rebates do not come back - STCs were assigned and consumed at the original install, as explained on our STC certificate page, and the Cheaper Home Batteries rebate is a one-time claim per property. The insurer replaces the hardware at full retail. Insure the gross, not the net. This is the single most common and most expensive mistake we see.
What Cardinia storms actually do.
Hail is a standard covered peril under almost every Australian home policy, so a genuine hail strike on a compliant array is usually a straightforward claim. Cardinia Shire does get real hail events, and while Tier-1 panels are impact-tested under IEC 61215 to survive 25mm ice balls at terminal velocity, a severe storm can exceed that.
The catch is causation. Insurers pay for damage caused by the hail, not for an array that was already degraded, already had a failed inverter, or was mounted non-compliantly and would have come loose in the next big westerly anyway. Which is exactly why the dated evidence in your file matters so much before anything happens.
Wind is the quieter risk and the one that generates the arguments. We sit in AS/NZS 1170.2 wind region A, and the westerly fronts that come off the flat Koo Wee Rup plain load an array hard - particularly along the edge and corner zones of a roof, where uplift pressures run several times higher than mid-roof. When an array lifts in a Pakenham storm, the assessor's first question is whether the mounting matched the engineered layout for those zones. If it did not, that is an installation defect and the storm was merely the trigger. Your claim is now a fight with the original installer, who in the 2014-2017 cohort has often long since left the industry.
The hail damage you cannot see.
The nasty one. A hail strike frequently leaves the glass visually intact while creating microcracks in the silicon cells underneath. The array keeps generating and nothing looks wrong from the driveway, so no claim is lodged. Output then decays over the following two or three years as the cracks propagate and cells develop hot spots.
By the time you notice the generation drop on the bill, the storm event is well outside any sensible claim window and the insurer reasonably says it is degradation. If Pakenham cops a serious hail event, get the array properly inspected within days even if it looks fine and even if it is still generating. Electroluminescence testing finds microcracks that no visual inspection will. That inspection report, dated to the storm, is what converts a future argument into a paid claim. Our solar repairs and servicing team handles post-storm assessments across the Shire.
Shut it down, photograph, then claim.
In that order, and do not get on the roof.
Switch off at the AC isolator using the sequence in your inverter manual. Do not touch the DC side: broken panels and damaged cabling on a roof can still be sitting at 500 to 600 volts DC in daylight, and unlike your AC circuits you cannot switch it off. There is no breaker on the sun. A damaged array is one of the few genuinely dangerous things a storm can leave on a house, and every summer somebody climbs up to have a look at it.
Photograph everything from the ground with a zoom, including wide shots that establish the whole roof and the address. Photograph any hail on your lawn next to a coin or a ruler for scale before it melts - that timestamped image is often the single most useful thing in the file, because it independently establishes the hail size against which the IEC rating is judged. Photograph the inverter display and any error code. Screenshot the monitoring app showing the generation cliff.
Then call your insurer to open the claim and get a claim number, then call us for the make-safe and the assessment report. We attend Pakenham, Officer and the wider Cardinia Shire same or next day for storm make-safe, isolate the system properly, document the damage to the standard assessors expect, and write the report your insurer will actually accept.
The file you should already have.
Claims are won and lost on paperwork prepared before the event. Keep these together, somewhere that is not the kitchen drawer in the house that might burn down:
- Certificate of Electrical Safety for the original install
- United Energy connection approval - see our grid connection page
- CEC installer accreditation number and the itemised install invoice
- Panel and inverter warranty documents and serial numbers
- AS/NZS 5139 compliance documentation if you have a battery
- Dated photos of the array in good condition, and your monitoring history - a clean generation record is the best possible proof the system was healthy the day before
Unlicensed work voids more than you think.
Almost certainly not covered, and the exposure runs to the whole house rather than just the array. Home policies routinely exclude loss caused by unlawful or non-compliant work and require that fixed electrical work was done by a licensed tradesperson. If a fire starts at an unlicensed DC connection, the investigator asks for the Certificate of Electrical Safety and the United Energy connection approval, and if they do not exist the conversation is over.
The same logic applies to a compliant system with a missing paper trail. If you cannot produce the CoES, the CEC installer accreditation number and the approval, you are arguing from a much weaker position even when the work was genuinely fine. We go through the licensing position in full on our DIY solar vs a CEC installer page.
Batteries and your premium.
A battery can affect your premium, and you must disclose it. Some insurers rate a lithium battery as an increased risk and adjust the premium modestly; some do not blink. What they all care about is compliance, because a compliant install is a genuinely low-risk one.
AS/NZS 5139 governs battery energy storage installation and sets the rules on location, clearances, separation from habitable rooms and exit paths, and fire-rated barriers. That standard is the reason we sometimes cannot put the unit exactly where you want it, and the reason a battery on the garage wall two metres from the door is a design decision rather than a convenience. Get the AS/NZS 5139 compliance documentation into your insurance file on day one. If you are weighing up brands, our battery comparison and battery storage pages cover the detail.
Insurance questions we get asked.
Does home insurance cover solar panels in Pakenham?
In most cases yes, but as part of the building sum insured rather than as a separately listed item - panels are a fixture, like a pergola or a hot water unit. That distinction matters more than people realise. If your building sum insured was set before you spent $8,000 on solar and another $12,000 on a battery, you are now underinsured by roughly that amount, and in a total loss the shortfall is yours.

Are solar panels covered for hail damage?
Hail is a standard covered peril under almost every Australian home policy, so a genuine hail strike on a compliant array is usually a straightforward claim. Cardinia Shire does get real hail events, and while Tier-1 panels are impact-tested under IEC 61215 to survive 25mm ice balls at terminal velocity, a severe storm can exceed that.

What should I do straight after storm damage to my solar system?
Shut it down, then photograph, then claim - in that order, and do not get on the roof. Switch off at the AC isolator using the sequence in your inverter manual. Do not touch the DC side: broken panels and damaged cabling on a roof can still be sitting at 500 to 600 volts DC in daylight and there is no breaker on the sun.

Will my insurer cover a solar system installed by an unlicensed person?
Almost certainly not, and the exposure runs to the whole house rather than just the array. Home policies routinely exclude loss caused by unlawful or non-compliant work and require that fixed electrical work was done by a licensed tradesperson. If a fire starts at an unlicensed DC connection, the investigator asks for the Certificate of Electrical Safety and the United Energy connection approval, and if they do not exist the conversation is over.
