Solar Company Insurance in Perth: Why It Matters and What to Check Before Signing

TL;DR: Before signing a Perth solar contract, verify three insurance covers held by the installing company: public liability of at least $5M (covers damage to your property during install), professional indemnity of at least $2M (covers design errors and incorrect advice), and workers’ compensation insurance (covers any injuries to install team on your roof). Without these, a Perth homeowner is exposed to thousands of dollars in personal liability if anything goes wrong. CEC Approved Retailers like Talk Energy are required to carry these as a minimum.

The four insurance types that matter for Perth solar

1. Public liability insurance

Covers damage caused to your property or third-party property during install. A cracked roof tile, fallen panel, damaged ceiling from cable feed — all are public liability claims. The CEC requires $5M minimum for Approved Retailers. Talk Energy carries $10M public liability.

Why this matters in Perth: working at heights on tile roofs in a 35–45°C summer afternoon is a real-world environment where minor accidents happen. Without public liability cover, a $4,000 roof repair becomes a contract dispute that you, the homeowner, may have to pursue through small claims court.

2. Professional indemnity insurance

Covers design errors and incorrect advice. If a system is mis-sized, panels are placed in shading, or the inverter is the wrong specification, professional indemnity is what funds the rectification. CEC minimum is $2M; Talk Energy carries $5M professional indemnity.

This is the cover most non-approved Perth retailers skip. It’s also the cover most often invoked when a customer claims performance shortfall (“my system isn’t producing what was promised”). Without it, the homeowner has no path to remedy short of legal action.

3. Workers’ compensation insurance

Legally required in WA for any employer. Covers injuries to install team while on your property. Critical for double-storey homes where working-at-heights injuries can occur. Subcontractor-heavy retailers sometimes have gaps here — if a subcontractor’s worker is injured on your roof and the subcontractor lacks proper cover, liability can flow up to you.

4. Product warranty backing

This is technically not insurance, but functions like it. CEC Approved Retailers commit to honouring product warranties for the life of the warranty period — typically 25 years for panels and 10 years for inverters and batteries. The financial-protection scheme administered by the CEC means that even if the retailer goes out of business, warranty claims can still be processed.

Non-approved retailers don’t participate in this scheme. If they close shop in year 4 of your install, your 25-year panel warranty becomes a direct-to-manufacturer claim — which often requires the manufacturer to dispatch a certified installer (at your cost) to verify the issue.

Real-world Perth scenarios where insurance matters

• Tile crack during install: public liability covers replacement of 3 cracked tiles ($300–$600). Without it, the customer disputes with the retailer or pays themselves.
• Cable channel damages painted gable: public liability covers repaint of fascia/gable ($800–$1,500).
• System under-performs by 20%: professional indemnity funds a re-engineering and panel relocation (~$2,000–$4,000).
• Inverter installed in wrong location, overheats and fails after 3 years: professional indemnity funds replacement and relocation (~$2,500–$4,000).
• Retailer goes bust in year 5: CEC financial-protection scheme processes remaining warranty claims.

What to ask your Perth solar retailer before signing

• “What is your public liability insurance amount?” — should be $5M minimum.
• “What is your professional indemnity insurance amount?” — should be $2M minimum.
• “Are your installers employed in-house or subcontracted?” — in-house preferred; if subcontracted, ask for the subcontractor’s insurance details too.
• “Are you a CEC Approved Retailer?” — verify on the CEC directory.
• “What’s your WA Electrical Contractor licence number?” — verify on EnergySafety WA.
• “What happens to my warranty if your company stops trading?” — should reference CEC financial protection or equivalent.

Why this matters more in 2026

The Federal Cheaper Home Batteries Program and the WA Residential Battery Scheme have driven a surge of new solar retailers into the Perth market in 2025–2026. Many are well-resourced and reliable; some are not. Industry data from the CEC shows that ~22% of newly-trading Australian solar companies fail within 5 years — well before warranties expire. Insurance and Approved Retailer status are the consumer’s primary protection against this.

Frequently asked questions

What insurance should a Perth solar installer have?

A minimum of $5M public liability, $2M professional indemnity, and current workers’ compensation insurance. CEC Approved Retailers carry these as standard; non-approved retailers often skip professional indemnity.

What happens if a Perth solar company damages my roof during install?

If the company has public liability insurance, their insurer pays for the repair. Without it, you’re left to pursue the company directly — which can become protracted if they’re under-resourced. Always verify public liability cover before signing.

What if my Perth solar company goes out of business?

If they were a CEC Approved Retailer, the CEC’s financial-protection scheme processes outstanding warranty claims and complaints. If they were not approved, you’re left to claim directly from manufacturers (which usually requires a certified installer at your cost) or take legal action against the company’s remaining assets.

Should I check the installer’s insurance myself?

Yes. Ask for a current Certificate of Currency from their insurance broker. This is a one-page document showing the insurance amount and validity period. Any reputable retailer provides this on request without hesitation.
