Solar Warranty Bossley Park: 2026 Checklist | Kratos Energy

Solar Warranty Checklist for Bossley Park: What Should You Check Before Buying?

When comparing solar quotes in Bossley Park NSW 2176, price, panel brand and system size usually receive most of the attention.

But a solar system is expected to operate for decades, so the warranties behind the equipment and installation can be just as important as the hardware itself.

A solar proposal may mention a 25-year warranty, but that does not necessarily mean every component, labour cost and installation issue is protected for 25 years.

A complete solar system can involve several different forms of protection: the solar panel product warranty, panel performance warranty, inverter warranty, workmanship warranty and your automatic rights under the Australian Consumer Law (ACL).

Understanding the difference before you sign can make a future warranty claim considerably easier.

Solar Warranties: The Quick Comparison

The most important point is that these protections are not interchangeable.

A 25-year solar-panel performance warranty does not automatically mean the installer will repair roof leaks, replace a failed inverter or pay all labour costs for 25 years.

Why Warranty Checks Matter for Bossley Park Homes

Bossley Park is predominantly a detached-house suburb. The 2021 Census recorded approximately 91.2% of occupied private dwellings as separate houses, while around 46.8% contained four or more bedrooms. The average household contained about 3.3 people. (Australian Bureau of Statistics)

For homeowners investing in a rooftop system expected to remain on the property for decades, the long-term support arrangement deserves attention before installation.

The important question is not simply:

“How long is the warranty?”

A better question is:

“What exactly is covered, who is responsible, and what happens if I need to make a claim?”

1. Solar Panel Product Warranty

The product warranty generally relates to defects in the physical solar panel.

Depending on the manufacturer's terms, examples may include faults involving materials, manufacturing quality or premature component failure.

When reading a product warranty, check whether it explains who pays for diagnosis, removal, replacement, freight and reinstallation.

A replacement panel may technically be provided under warranty while some associated labour or transport costs remain subject to separate terms.

Also check whether your exact panel model appears on the paperwork rather than relying only on the manufacturer's brand name.

2. Solar Panel Performance Warranty

A performance warranty is different.

Solar panels gradually lose some output as they age. The performance warranty normally promises that the panel will retain a specified percentage of its original rated performance after a defined period.

For example, a manufacturer might provide a long-term degradation schedule rather than promising that the panel will operate at 100% output indefinitely.

This warranty is mainly about power degradation, not every possible physical defect.

Before purchasing, identify:

Starting performance → annual degradation allowance → guaranteed output at the end of the warranty period.

Also read the method the manufacturer requires to prove abnormal degradation. A lower electricity bill alone does not necessarily demonstrate a panel failure because generation can also be affected by weather, shade, dirt, inverter performance and system configuration.

Product Warranty vs Performance Warranty

This distinction causes significant confusion.

When a quote simply says “25-year solar warranty,” ask the retailer to separate each warranty in writing.

3. Inverter Warranty

The inverter is a major component of the system and should have its own warranty.

Kratos Energy's current support information states that its Tier 1 panels carry a 25-year performance warranty, inverter warranties are typically 5–10 years, and its workmanship is guaranteed for 10 years. Exact coverage should still be checked against the equipment and contract supplied with your individual installation. (Kratos Energy)

When reviewing an inverter warranty, pay attention to more than the number of years.

Check whether it covers the whole inverter, whether replacement labour is included, whether freight is covered, and whether the manufacturer offers an optional warranty extension.

Also ask who handles the claim.

A clear solar proposal should tell you whether you contact the retailer, installer or manufacturer if the inverter reports a fault.

4. Workmanship Warranty

The workmanship warranty relates to how the solar system was installed, rather than a manufacturing defect in the equipment.

It can become relevant to issues involving mounting, cabling, roof penetrations, equipment positioning or other installation-related work.

This warranty is particularly important because a solar panel manufacturer is unlikely to be responsible for a problem caused by poor installation.

The Australian Competition and Consumer Commission states that where a consumer pays one solar supplier for both the equipment and installation, that supplier is generally responsible for providing a remedy when something goes wrong—even if it subcontracted the installation work. (ACCC)

That makes it worth asking before you buy:

Who is my contract actually with?

Ideally, the warranty paperwork should clearly identify the business responsible for installation support rather than leaving you to determine responsibility after a fault occurs.

Kratos' current residential offering states that its team manages design, installation, grid-connection paperwork and ongoing support, with warranty and aftercare forming part of the residential service. (Kratos Energy)

5. Your Australian Consumer Law Rights Are Separate

Manufacturer warranties are not your only protection.

The ACCC states that consumer guarantee rights apply to solar products and installation services and cannot be excluded or restricted. These rights exist separately from manufacturer's or retailer's voluntary warranties. (ACCC)

For goods, this can include expectations around acceptable quality, fitness for purpose and reasonable durability. Installation services must also be provided with due care and skill and be fit for a purpose communicated to the supplier. (ACCC)

This is important because:

A written warranty expiring does not automatically mean every legal consumer right has disappeared.

NSW Fair Trading similarly states that a business must honour consumer guarantees even when a separate warranty or extended warranty does not apply. (NSW Government)

Check the Installer and Equipment Before Installation

Warranty quality is only one part of protecting your solar investment.

For a rooftop system to meet current Small-scale Renewable Energy Scheme requirements, the Clean Energy Regulator says the designer and installer must hold appropriate accreditation, with solar installers/designers accredited through Solar Accreditation Australia (SAA). Relevant panels and inverters must also appear on the approved product lists. (Clean Energy Regulator)

Before accepting a Bossley Park solar quote, your paperwork should therefore allow you to confirm the installer, equipment models and warranty providers.

A long warranty is considerably less useful if you cannot identify which equipment was installed or which company is responsible for the claim.

Solar Warranty Checklist Before You Sign

Use this checklist when comparing Bossley Park solar proposals:

Do not rely only on verbal promises made during the sales process.

Keep the final written contract and warranty documents.

What Documents Should You Keep?

After your solar system is commissioned, keep one digital folder containing your contract, final invoice, panel and inverter model numbers, equipment serial numbers, warranty documents, system design, electrical compliance documentation, grid-connection information and monitoring login details.

NSW Fair Trading says homeowners should receive system documentation including equipment information, operating instructions, connection diagrams and relevant electrical compliance documentation. (NSW Government)

These records can make a warranty claim much easier several years later.

Take photographs of the inverter label and serial numbers as an additional backup.

How to Make a Solar Warranty Claim

If a problem develops, use a structured process rather than contacting several companies simultaneously.

Step 1 — Identify the problem

Check your monitoring application for warnings, abnormal production or inverter error codes. Photograph any visible issue, but do not open or alter electrical equipment yourself.

Step 2 — Find your installation records

Locate the invoice, contract, warranty paperwork, model numbers, serial numbers and installation date.

Step 3 — Contact the solar supplier

If one company supplied and installed the system, the ACCC says that business is generally responsible for dealing with problems affecting the products or installation. (ACCC)

Describe the fault clearly and provide supporting evidence.

Step 4 — Allow the system to be assessed

Some issues can be diagnosed remotely through inverter monitoring. Others may require an on-site inspection.

Step 5 — Confirm the proposed remedy in writing

Depending on the problem and applicable rights, the remedy might involve repair, replacement or another appropriate solution.

Kratos customers can lodge system issues through the company's dedicated Warranty & Support page, which currently provides support-ticket, telephone and email options. (Kratos Energy)

Step 6 — Escalate if the issue remains unresolved

If a NSW homeowner cannot resolve an installation-related dispute with the contractor, NSW Fair Trading provides a complaint-handling service. In applicable cases, unresolved disputes can ultimately proceed to the NSW Civil and Administrative Tribunal. (NSW Government)

Warning Signs in a Solar Warranty

A warranty deserves closer investigation when important details are vague.

Be cautious when a proposal promotes a single long warranty number but does not separate the panel product, panel performance, inverter and workmanship coverage.

Also look carefully at terms that make it unclear who pays labour or freight, require you to deal with an overseas manufacturer without local support, or fail to identify who handles installation-related faults.

Another concern is relying purely on the manufacturer's longevity.

A strong warranty arrangement should explain the local claims pathway, not simply present a logo and warranty duration.

Does a 25-Year Warranty Mean Your Whole Solar System Is Covered for 25 Years?

No.

Different components normally have different warranty periods.

For example, a panel may carry a long-term performance warranty while an inverter has a shorter equipment warranty and the installation is protected under a separate workmanship arrangement.

This is why homeowners should compare solar proposals using a warranty matrix, not one headline number.

The important question is:

What happens if each individual component fails in year 2, year 7, year 12 or year 20?

If the quote cannot answer that clearly, ask before signing.
