Solar Panel Cleaning Insurance in Australia: What Is Covered and What Is Not
Solar panel cleaning overlaps with home and contents, public liability, and product warranties. Here is how to make sure you are actually covered and what gaps most homeowners do not know about.
When a solar panel cleaner steps onto your roof, several different insurance frameworks interact: the cleaner’s own public liability policy, your home and contents insurance, your panel manufacturer’s product warranty, and your inverter warranty. Most Australian homeowners have no idea how these interact — or what happens when something goes wrong.
This guide explains what is and is not covered, what questions to ask your insurer, and how to protect yourself before any cleaning work begins.
The Four Insurance Frameworks That Apply to Solar Cleaning
1. Your Home and Contents Insurance
Your household policy is relevant in two scenarios: if the cleaner damages your system and their public liability insurer refuses a claim (or they have no insurance), your accidental damage cover is your backstop; and if an accident during cleaning damages other property (for example, a cleaner drops a tool through a skylight or damages a gutter), this may be claimed through your policy or the cleaner’s — depending on who is at fault.
What to check in your PDS:
- Are solar panels included in the building definition? (Most modern policies include them as fixtures)
- Do you have accidental damage cover? (Optional in many policies — often costs an extra $50 to $150 per year to add)
- What is your building sum insured — does it reflect the replacement cost of your solar system?
- Is there an exclusion for damage caused by cleaning, maintenance, or repair activities? (Some policies exclude damage occurring during maintenance)
The most common gap: homeowners with fire, theft, and natural disaster only building cover (no accidental damage component) have no coverage if a cleaner cracks a panel or breaks mounting hardware through negligence — this falls entirely to the cleaner’s public liability policy.
2. The Cleaner’s Public Liability Insurance
Public liability (PL) insurance is the primary protection for you when engaging any contractor. It covers physical damage to your property and personal injury caused by the contractor’s negligence during their work.
Minimum acceptable coverage: $10 million. This is the industry standard for any contractor performing work at heights on residential property in Australia. Many strata managers and insurers require $20 million.
What PL insurance covers:
- Accidental breakage of a solar panel during cleaning
- Damage to roof tiles, gutters, or cladding caused by cleaning equipment
- Injury to a third party caused by the contractor’s activities on your property
- Damage from chemical spills or runoff from cleaning products
What PL insurance does NOT cover:
- Deliberate or fraudulent acts by the contractor
- Damage caused by a subcontractor who is not covered under the policy
- Business loss (lost output from a damaged system)
Always request a Certificate of Currency — a current document from the insurer confirming the policy is active, the insured name, the coverage amount, and the expiry date. Verbal assurances that they are fully insured are not sufficient.
3. Panel Manufacturer’s Warranty
Solar panel warranties cover manufacturing defects — they do not cover damage caused by improper cleaning. The warranty is voided by pressure washing above the manufacturer’s specified pressure (typically 30 to 40 psi maximum), use of abrasive materials (abrasive pads, steel wool, hard brushes), use of harsh chemicals (solvents, acid-based cleaners, alkali-based cleaners above the manufacturer’s pH range), and physical damage during installation or maintenance.
The insurance implication: If a cleaner uses a pressure washer and voids your warranty, you have no warranty protection against future panel degradation. Your claim for warranty-equivalent compensation comes through the cleaner’s PL policy and/or Australian Consumer Law.
Major Australian panel brands’ cleaning guidelines: LG Legacy warranty specifies soft brush plus mild pH-neutral detergent or water only; SunPower Maxeon specifies clean water and soft cloth with no pressure washer; Trina Solar specifies pH 6 to 8 cleaning solution with soft brush and no pressure over 35 psi; Canadian Solar specifies mild soapy water with no pressure washer and no abrasive tools; REC Group specifies soft cloth or sponge with mild detergent and no pressure washer.
4. Inverter Warranty
Inverter warranties are distinct from panel warranties and are rarely affected by cleaning — unless a ground fault caused by panel damage (for example a cracked panel from improper cleaning) trips the inverter protection circuitry repeatedly and causes inverter damage. In this chain-of-cause scenario, the inverter manufacturer will seek proof that the damage resulted from external causes, and the original fault (the cracked panel from cleaning) sits with the cleaner’s PL insurance.
Scenarios and Who Pays
Scenario 1: Cleaner Cracks a Panel With Their Equipment
Coverage: cleaner’s public liability insurance pays for panel replacement (typically $300 to $600 installed). If they have no insurance, your accidental damage cover (if you have it) is your fallback, with the right to pursue the cleaner under Australian Consumer Law.
Scenario 2: Cleaner Uses a Pressure Washer, Voiding Warranty
Coverage: not a physical damage claim — a warranty loss claim. The cleaner is liable under ACL for the diminished value of your system. This requires documentation and possibly legal proceedings, but you have clear grounds. PL insurance may cover this but coverage depends on how damage is defined in the policy.
Scenario 3: Hail Damages Panels During the Clean
Coverage: natural disaster (hail) goes through your home and contents building cover. The cleaner has no liability for weather events. Make sure your building sum insured covers the full replacement cost of your solar array.
Scenario 4: Cleaner Falls and Is Injured on Your Roof
Coverage: the cleaner’s own workers compensation insurance (if employed) or personal accident insurance (if self-employed). Your home and contents policy typically includes public liability cover for incidents on your property, but a professional contractor’s work injury is almost always the contractor’s own insurance responsibility.
Scenario 5: DIY Cleaning Results in a Fall
Coverage: your personal accident insurance (if you hold it — many Australians do not), and Medicare for medical costs only. There is no insurance for a homeowner who falls off their own roof doing DIY cleaning. This is the primary reason professional cleaning is strongly recommended for any elevated access.
Before You Book: Insurance Checklist for Homeowners
Ask your cleaner before booking:
- Can you provide a Certificate of Currency for your public liability insurance?
- What is your coverage amount?
- Do you hold current workers compensation insurance for your staff?
- Do you hold a Working at Heights qualification?
- What cleaning method and solution do you use — is it compliant with panel manufacturer guidelines?
- Can you provide a written service agreement?
Check your own policy:
- Review your home and contents PDS for solar panel coverage definition
- Confirm your building sum insured includes the solar system replacement cost
- Confirm whether you have accidental damage cover (and add it if not)
- Note any exclusions for maintenance or cleaning activities
Document before cleaning:
- Photograph your panels before the clean
- Record current inverter output (kWh today vs prior day)
- Keep your panel warranty documents accessible
Australian Consumer Law: Your Backstop Right
Regardless of insurance outcomes, if a solar cleaner causes damage through substandard work, you have rights under the Australian Consumer Law (Schedule 2 of the Competition and Consumer Act 2010). Consumer guarantees apply to services: work must be carried out with due care and skill, be fit for purpose, and completed in a reasonable time. If a cleaner’s work damages your system, they are required to remedy it — by repair, replacement, or compensation. If they refuse, you can escalate to your state’s consumer tribunal (NSW Fair Trading, Consumer Affairs Victoria, Office of Fair Trading QLD, etc.) without needing a lawyer. Monetary claims up to $25,000 (varying by state) can be heard in state tribunals at minimal cost.
Summary
Insurance for solar panel cleaning is a multi-layered issue, and the gaps are where homeowners get caught out. The three essentials:
- Engage only cleaners with current $10 million or higher public liability insurance — request the Certificate of Currency before they step on your roof
- Check your own home and contents policy for solar panel coverage and consider adding accidental damage cover if you do not have it
- Document your warranty terms and your system’s current condition before any cleaning work — this is your evidence base if a dispute arises
The $200 to $300 professional clean is only cheap if the cleaner is properly insured. An uninsured cleaner who damages a panel and disappears is a $300 to $600 problem with no easy resolution.

Frequently Asked Questions
Most comprehensive home and contents policies in Australia cover accidental damage to solar panels during cleaning, for example if a cleaner accidentally cracks a panel. However, this usually falls under accidental damage cover, which is not included in all policies. Check your Product Disclosure Statement specifically for solar panels and accidental damage clauses. Some policies list solar panels as fixtures and fittings included under the building sum insured; others require a separate schedule or endorsement.
A professional solar panel cleaner should carry: (1) Public liability insurance at minimum $10 million, covering damage to your property or injury caused by their work; (2) Workers compensation insurance, mandatory if they employ staff, covering their workers if injured on your property; (3) Tool and equipment insurance, covering their equipment. Always ask for a Certificate of Currency before work begins. A cleaner without public liability insurance should not be engaged.
Yes, through Australian Consumer Law (ACL). If a cleaner's improper methods such as using a pressure washer or harsh chemicals void your panel warranty and damage the panels, you can pursue them under ACL for damages equivalent to the warranty loss. This requires you to document the damage, obtain a written assessment from your installer confirming warranty void, and demonstrate the cleaner's method was the cause.
This varies by insurer and policy. Most policies treat solar panels as fixtures attached to the building and cover them under the building/structure component of the policy, not contents. This matters because building cover typically applies to fire, storm, and hail, but not always to accidental damage without an explicit endorsement. Always read the definition of building in your PDS and confirm solar panels are listed or confirm directly with your insurer.
If a homeowner falls while performing DIY solar panel cleaning, they are covered by Medicare for medical costs but there is generally no other personal accident insurance unless they hold a specific personal accident policy. Workers compensation does not apply to homeowner DIY activities. The financial and physical risk of DIY cleaning on elevated roofs is the primary reason professional cleaning is recommended.
