Quick answer: Yes, most Ontario home insurance policies cover rooftop solar panels under dwelling coverage. But coverage is not automatic. You must notify your insurer before installation, update your dwelling coverage limit to reflect the replacement value of the solar system, and confirm your policy explicitly covers solar-related perils. The typical annual premium increase is $75 to $150 for a standard residential system.
In September 2024, CBC News reported that some Canadian homeowners were running into unexpected insurance problems after installing solar panels. The issues ranged from premium surprises to coverage gaps that left homeowners underinsured.
The good news: these problems are avoidable. If you notify your insurer at the right time, ask the right questions, and update your coverage before installation, solar panels are straightforward to insure in Ontario. The bad news: most homeowners skip these steps because nobody tells them.
This guide covers exactly how Ontario home insurance treats solar panels, what is and is not covered, how your premiums will change, and the five steps to take before your installer arrives. Every fact is sourced from Canadian insurance brokers, Ontario-based insurers, and verified against multiple industry publications.
How Solar Panels Are Covered Under Ontario Home Insurance
Ontario home insurance policies do not have a separate "solar panel" category. Your panels are covered under existing sections of your policy depending on how they are installed.
Rooftop solar panels are treated as part of your home's structure, the same way a new roof, dormer, or skylight would be. They fall under dwelling coverage (sometimes called Coverage A). This means your panels are protected against the same perils that protect your house: fire, lightning, theft, vandalism, and most weather events. (LowestRates.ca)
The most-missed detail
Your dwelling coverage has a maximum limit. This is the total amount your insurer would pay to rebuild your home from scratch. If you add $25,000 worth of solar panels without increasing this limit, your home is underinsured. In a total loss scenario (fire, for example), your payout may not cover both the house rebuild and the solar system replacement. (ThinkInsure)
Ground-mounted solar panels (installed on a freestanding frame in your yard) fall under "other structures" coverage (Coverage B). This is the same section that covers your detached garage, shed, or fence. Standard Ontario policies cap other structures coverage at 10% of your dwelling limit. On a $400,000 dwelling policy, that means $40,000 total for all other structures combined. If your ground-mounted system costs $30,000 and you already have a $15,000 detached garage, you exceed the limit and need an endorsement or rider.
What Your Policy Covers and What It Does Not
Understanding the specific inclusions and exclusions before you file a claim prevents surprises.
Covered (standard policy)
- Fire damage to panels or caused by panels
- Lightning, including electrical surge to inverters and wiring
- Theft and vandalism (rooftop)
- Wind damage and fallen tree limbs
- Weight of ice and snow accumulation
- Third-party liability (detached panel hits property/person)
NOT covered (standard policy)
- Equipment breakdown (inverter internal failure)
- Normal wear / panel degradation (0.3-0.5% per year)
- Faulty installation damage (installer liability)
- Lost net metering revenue if system goes offline
- Hail damage (some Ontario insurers exclude or add deductible)
Equipment breakdown is the big one. If your inverter fails due to an internal defect (not caused by lightning or a covered peril), standard home insurance does not pay for it. This requires a separate equipment breakdown endorsement. Aviva Canada's Green Home Power endorsement is one of the few options that includes this coverage. (Acera Insurance)
Normal wear and panel degradation (typically 0.3% to 0.5% per year) is not an insured peril. This is covered by your panel manufacturer's 25-year performance warranty, not your home insurance.
Faulty installation damage is not your home insurer's responsibility. It falls under your installer's commercial general liability insurance. This is one reason to always use an ESA-licensed contractor who carries adequate liability coverage. Solar X carries full commercial liability insurance on every installation and is verified through The Home Depot Canada's Local Pro program. (Solar X Home Depot Local Pro)
Lost net metering revenue is not covered by standard policies. If your system goes offline and you stop earning net metering credits, most Ontario policies do not compensate for that lost revenue. Aviva's Green Home Power endorsement does cover this.
Check your specific policy for hail coverage. While Ontario does not experience the severe prairie hailstorms common in Alberta and Saskatchewan, hail events do occur and can crack panel glass. Some Ontario insurers exclude hail damage to rooftop solar or apply a separate, higher deductible. Confirm this with your insurer before installation.
How Much Solar Panels Increase Your Ontario Home Insurance Premium
Solar panels increase your home's replacement value, which means you need a higher dwelling coverage limit, which increases your premium. The math is straightforward.
A typical Ontario residential solar system costs $17,000 to $32,000 installed. Your insurer needs to factor in that replacement cost on top of the house rebuild in a total loss scenario.
Typical annual premium increase
$75 to $150 per year
Based on data from multiple Canadian insurance and solar industry sources, including SolarDirect Canada (an Ontario installer with over 30,000 installations) and Green Building Canada. Some insurers also apply a flat solar surcharge of $50 to $75 per year for the added electrical complexity, on top of the dwelling coverage increase.
To put this in context: $150 per year on a $25,000 solar system is 0.6% of the asset's value annually. The system itself can save most Ontario homeowners $1,500 to $2,400 per year on electricity (depending on usage, rate plan, and system size), so the insurance cost is a small fraction of the savings.
A few homeowners ask whether solar panels can lower their premiums through green energy discounts. In Canada, this is uncommon. A small number of insurers offer modest discounts (5% to 10%) for energy-efficient homes, but this is not standard practice in Ontario. The net effect on premiums is a modest increase, not a reduction.
Ontario-Specific Insurance Considerations
Ontario homeowners face insurance situations that differ from other provinces.
ESA Certificate of Acceptance
After your solar installation passes the mandatory Electrical Safety Authority (ESA) inspection, you receive a Certificate of Acceptance. Some Ontario insurers request this document as proof that the installation was completed safely and to code. Keep it with your insurance paperwork. (Erie Mutual) Solar X provides this certificate to every customer after the ESA inspection passes.
Net Metering and Liability
If you participate in Ontario's net metering program and export surplus electricity to the grid, you are technically operating as a micro-generator. Most standard home insurance policies cover this without issue, but confirm with your insurer that your liability coverage extends to grid-connected generation.
Battery Storage
If you install a battery alongside your solar panels ( Tesla Powerwall 3, Enphase IQ Battery, or Growatt APX), the battery adds to the replacement value and should be included in your dwelling coverage update. Some insurers ask about battery chemistry. LiFePO4 (lithium iron phosphate) batteries have a significantly better safety profile than older lithium-ion chemistries, and some insurers view them more favourably. Mention your battery type when notifying your insurer. For details on battery options, see our home battery storage guide.
HRSP Rebate and Insurance
The Home Renovation Savings Program rebate (up to $10,000 for solar plus battery) does not reduce your insurable value. Your insurer covers the full replacement cost of the system, not the net cost after rebates. If your system cost $28,000 installed and you received $10,000 in HRSP, your dwelling coverage should reflect $28,000.
Roof Condition
Before installing solar, assess your roof age. If your roof is over 15 years old, some insurers may require a professional inspection before approving coverage for solar. Solar X evaluates roof condition during every free assessment and will tell you honestly if your roof needs attention before panels go on. (Solar X Home Upgrades Guide)
Which Ontario Insurers Handle Solar Panels Well
Not all Ontario insurers approach solar the same way. Based on publicly available industry information:
- Aviva Canada offers the Green Home Power endorsement, a purpose-built add-on for solar-equipped homes. It covers panel damage, equipment breakdown (including inverter failure), and net metering revenue interruption. This is the most solar-specific endorsement available from a major Canadian insurer. (Acera Insurance)
- Intact Insurance, Canada's largest property and casualty insurer, generally covers rooftop solar under standard dwelling coverage without a special endorsement. Terms vary by broker and by region within Ontario, so confirm through your specific broker.
- Co-operators, TD Insurance, and Wawanesa vary in their approach. Some broker channels handle solar routinely, while others are less familiar. Confirm coverage in writing before installation regardless of which insurer you use.
- Erie Mutual, an Ontario-based mutual insurer, has published specific guidance recommending that homeowners update dwelling coverage when adding solar panels. They note that grid-connected and off-grid systems may have different coverage rules. (Erie Mutual)
If your insurer cannot provide clear written answers about solar coverage, consider switching to a solar-experienced insurer before installation. The difference between an informed insurer and an uninformed one can be significant at claim time. (RateHub.ca)
5 Steps to Protect Your Insurance Before Solar Installation
Notify your insurer in writing before installation begins
Call your insurer or broker. State the system size (in kilowatts), the type (rooftop or ground-mounted), the estimated installed value, and your planned installation date. Follow up by email. This creates a paper trail and prevents the "undisclosed material change" issue that can void coverage.
Update your dwelling coverage limit
Ask your insurer for your current dwelling coverage amount. Add the full replacement cost of your solar system (the installed cost, not the post-rebate cost). Request the limit be increased and confirm the new limit and premium change in writing.
Confirm specific perils are covered
Ask explicitly: Does my policy cover hail damage to solar panels? Wind damage? Theft? Does equipment breakdown (inverter failure) require a separate endorsement? Does net metering activity affect my liability coverage? Get all answers in writing.
Confirm battery coverage if applicable
If installing battery storage, confirm the battery is included in your dwelling coverage. Ask whether your insurer has requirements around battery chemistry or installation standards.
Keep your ESA Certificate of Acceptance with your insurance documents
After your ESA inspection passes, Solar X provides a Certificate of Acceptance. Some Ontario insurers request this as proof of compliant installation. It also documents that the work was performed by an ESA-licensed electrical contractor (Solar X ESA Licence 7017538).
Frequently Asked Questions About Solar Panels and Home Insurance in Ontario
Do I need to tell my insurance company about solar panels?
Yes. Adding a $17,000 to $32,000 solar system to your home is a material change that must be disclosed. Failure to notify can result in denied claims or policy cancellation. Call your insurer before installation and follow up in writing.
How much will solar panels increase my home insurance in Ontario?
Most Ontario homeowners see a premium increase of $75 to $150 per year. This reflects the higher replacement value of your home. The increase is modest compared to the $1,500 to $2,400 in annual electricity savings most Ontario solar customers achieve.
Does home insurance cover hail damage to solar panels in Ontario?
Most Ontario policies cover hail damage, but some insurers exclude it or apply a higher deductible. Confirm hail coverage explicitly with your insurer in writing before installation. Ontario does not see the severe prairie hailstorms common in Alberta and Saskatchewan, but hail events do occur and can crack panel glass.
What happens to my solar panels if I sell my house?
Owned solar panels transfer to the new homeowner at closing. The buyer's insurer will need to include the system in their dwelling coverage. Provide the buyer with system specifications, warranty documents, and the ESA Certificate of Acceptance. Solar panels typically increase home value by 3 to 4 percent in Ontario.
Does my insurer need my ESA Certificate of Acceptance?
Some Ontario insurers request it as proof that the installation meets the Ontario Electrical Safety Code. Keep it with your insurance paperwork. Solar X provides it after every successful ESA inspection. The Certificate also documents that the work was performed by an ESA-licensed electrical contractor.
Are battery storage systems covered under home insurance?
Battery systems installed with solar are typically covered under dwelling coverage in Ontario. Notify your insurer about the battery type, capacity, and chemistry. LiFePO4 (lithium iron phosphate) batteries are viewed more favourably by insurers than older lithium-ion chemistries due to a lower fire risk profile.
What if my insurer refuses to cover solar panels?
Consider switching to a solar-experienced insurer before installation. Aviva Canada's Green Home Power endorsement is purpose-built for solar homes, covering equipment breakdown and net metering revenue loss. Confirm coverage in writing before the panels go on the roof.
Does the HRSP rebate affect my insurance coverage?
No. Your insurer covers the full replacement value, not the post-rebate cost. A $28,000 system with $10,000 in Home Renovation Savings Program rebates should be insured at $28,000. The rebate reduces what you pay; it does not reduce what it costs your insurer to replace the system.
Is equipment breakdown (inverter failure) covered?
Not under standard home insurance. Inverter failure from internal defects requires a separate equipment breakdown endorsement. Aviva Canada's Green Home Power includes this coverage. For other perils such as lightning surge damage or fire, standard dwelling coverage applies.
Can I install solar panels without telling my insurer?
You can, but you should not. Installing solar without disclosure is an undisclosed material change to your home. If you later file any claim, even unrelated to solar, your insurer can deny it or cancel your policy based on non-disclosure. The five minutes it takes to call your broker is not worth the risk.
