Solar and Home Insurance in Australia: What Coastal Homeowners Should Check
Your solar system is a major home asset, but it's not always covered by your home insurance the way you'd think. Most Australian insurance policies cover solar as part of home and contents, but the coverage details, exclusions, and claim processes have nuances that catch homeowners out, particularly when storm or pest damage occurs. For coastal Erina homes (where storm exposure and salt-related damage are higher), getting the insurance setup right matters more than for inland properties.
### What standard home insurance typically covers
Most Australian home and contents policies cover solar systems as "buildings", the panels, mounting hardware, inverter, and associated wiring are treated as part of the dwelling. Standard coverage usually includes:
- Storm damage. Hail, wind, falling tree branches, and lightning are typically covered events. - Fire damage. Both fire affecting the panels and electrical fires originating in solar components. - Theft. Less common in Australia but covered for the array itself in most policies. - Accidental damage. Some policies include this for the system; others require an add-on.
Coverage is typically based on the dwelling sum insured, the rebuild cost of the home, which includes the solar system. As long as your dwelling sum insured reflects the full rebuild cost (including solar), the system is covered in proportion.
### Common exclusions worth checking
The fine print varies between insurers, but some exclusions appear frequently:
Pest and vermin damage. If pigeons nesting under panels damage wiring, or rodents chew through cables, many policies exclude this. The reasoning is that pest damage is considered preventable maintenance, not an insurable event. If you don't have bird mesh installed, this exclusion can be costly.
Lack of maintenance. Damage that develops gradually from poor maintenance (loose mounting, untreated rust, etc.) is often excluded. Insurers want to see reasonable upkeep.
Wear and tear. Normal aging of components, panels degrading slightly over time, inverters reaching end of life, is not insurance-covered. That's manufacturer warranty territory.
Unapproved installation work. Damage from DIY installation, or installation by someone who wasn't appropriately accredited, is often excluded. The system needs to have been installed properly by an SAA accredited installer to maintain coverage in most cases.
Specific coastal exclusions. Some policies have salt-related corrosion exclusions for properties within a certain distance from the coast. This can affect Erina homes very close to the water more than those further inland.
Solar export equipment. Some policies cover the panels and inverter but treat the smart meter, monitoring equipment, or grid connection as separate categories, sometimes covered, sometimes not.
### What to check on your specific policy
Five questions worth asking your insurer (or finding in your product disclosure statement):
1. What's the dwelling sum insured? Does it include the rebuild cost of the solar system, or does it predate the solar install?
2. Are there specific solar exclusions? Bird damage, salt corrosion, lightning surge, etc.
3. What's the excess for solar damage claims? Some policies have higher excesses for solar-related claims.
4. Are there installation requirements for coverage? SAA accreditation, CEC approved equipment, documented install paperwork.
5. Does the policy cover replacement cost or depreciated value? Old policies sometimes pay depreciated value of older systems; better policies pay full replacement cost.
If your home insurance policy was set up before you installed solar and you haven't updated it, your sum insured may not reflect the added value of the system. Many homeowners are underinsured for solar simply because they forgot to update the policy after installation.
### Coastal-specific considerations
Erina homes near the coast face two specific exposures:
1. Storm and salt damage. East Coast Low weather systems regularly bring strong winds, heavy rain, and salt-laden air across the Central Coast. Solar systems are exposed to this directly. Salt-related corrosion of mounting hardware and panel frames develops over years.
Some insurers have specific clauses about properties within X kilometres of the coast, additional excesses, exclusions for corrosion damage, or higher premiums. Worth checking specifically.
2. Lightning strikes. The Central Coast experiences more thunderstorm activity than parts of inland NSW. Direct lightning strikes are rare but devastating, they can destroy inverters and damage panels. Indirect strikes (surges from nearby lightning) are more common and damage electronics including inverters.
Surge protection devices fitted at install time reduce risk, and most modern inverters include some built-in surge protection. Insurance should cover lightning damage but the claim process is smoother with documented surge protection and proper grounding.
### Insurance and CTP (Cheaper to Power) financing
Some homeowners install solar through finance products, whether through traditional home loans, separate solar loans, or "buy now, pay later" arrangements. Insurance interacts with finance in important ways:
Finance companies often require insurance. Solar financed through a lender usually has a clause requiring the system to be insured. Confirm this in your loan documents.
Damage during finance period. If the system is damaged before the loan is paid off, the loan continues even if the system doesn't. Insurance payouts can clear or partially clear the loan, but the structure varies.
Loss after financing. Once the loan is paid, the system is fully yours and insurance is between you and the insurer. While financing, the lender may be a co-beneficiary on insurance claims.
### What to do when something goes wrong
If your solar system is damaged by an insurable event:
1. Document immediately. Photos of damage, weather records, anything else that supports the cause being an insurable event.
2. Don't repair before contacting the insurer. Some policies require insurer-approved assessment before work starts. Repairs done first can void claims.
3. Get a quote from an SAA accredited installer. The insurer will likely want quotes for assessment and repair from properly accredited tradespeople.
4. Submit the claim with full documentation. Include the original install paperwork (SAA accreditation, CEC equipment list, commissioning certificate) to streamline.
5. Follow up on processing time. Major insurers process solar claims within weeks for straightforward events. Complex claims (cause uncertain, fault investigation, etc.) take longer.
### Frequently Asked Questions
#### Does my home insurance go up after installing solar?
It depends on the insurer. Most policies treat solar as part of dwelling rebuild cost, so updating the sum insured may slightly increase premiums to reflect the added value. Some insurers offer specific solar policies or no premium changes for moderate-sized residential systems. Worth comparing.
#### What if my solar system causes damage, like an electrical fault that affects appliances?
Most home insurance policies cover damage caused BY the home's electrical system, but liability for installation defects typically rests with the installer's workmanship warranty rather than home insurance. Document any installation-related issues thoroughly.
#### Should I have specific solar insurance separate from home insurance?
For most residential systems, standard home and contents coverage with adequate sum insured is sufficient. Separate solar-specific insurance products exist but are rarely needed for typical residential installs. Larger commercial systems or systems with batteries may benefit from dedicated coverage, worth a conversation with a broker.
#### Does a battery system change my insurance coverage?
Yes. Batteries should be specifically mentioned in your sum insured and may trigger different premium rates or coverage requirements. Lithium-based home batteries have specific fire-risk considerations that some insurers price into premiums. Confirm with your insurer that your battery is fully covered and what (if any) installation requirements apply.
