How to read and understand your solar panel warranty
Understanding the intricacies of your solar panel warranty is crucial to protecting your investment. Solar panel warranties are typically complex documents, but breaking them down into key components can make them easier to comprehend.
1. Types of solar panel warranties
Solar panel warranties are guarantees manufacturers, and solar installers offer to protect your investment. They typically cover two main aspects: the physical condition of the panels (product warranty) and their ability to generate power over time (performance warranty). Understanding the details of each type of solar panel warranty is vital for making informed decisions and maximising the benefits of your solar system.
a. Product warranty (Solar panel manufacturer's warranty)
The product warranty, provided by the solar panel manufacturer, safeguards you against defects in materials and workmanship. This warranty typically ranges from 10 to 15 years, with some premium panels offering coverage extending to 25 years.
Here’s what a product warranty generally covers:
- Manufacturing defects: If a solar panel malfunctions due to a flaw in the manufacturing process, the manufacturer will repair or replace it under warranty terms.
- Material defects: Similar to manufacturing defects, this covers issues arising from faulty materials used in the panel’s construction.
- Power output: Some product warranties guarantee a minimum power output for a specific period. The manufacturer will rectify the situation if the panel’s output falls below this threshold due to a manufacturing defect.
Important points to consider:
- Warranty duration: While longer warranties offer greater peace of mind, prioritise reputable manufacturers with a proven track record over warranty length alone.
- Exclusions: Carefully review the warranty document to understand what’s not covered. This might include damage caused by natural disasters, improper solar installation, or neglect.
- Claims process: Familiarize yourself with the process for making warranty claims. This typically involves contacting the manufacturer and providing proof of purchase and solar installation.
b. Performance warranty
The performance warranty focuses on the solar panel’s ability to generate electricity over its lifespan. Most manufacturers offer a 25-year performance warranty, guaranteeing a minimum power output after 25 years.
Here’s how a performance warranty typically works:
- Degradation guarantee: Solar panel energy generation decreases gradually (called “degradation”). Solar panels naturally degrade in efficiency over time. A performance warranty assures that after the specified period (usually 25 years), the panel will still produce a certain percentage (usually 80-85%) of its original power output.
- Linear degradation: Performance warranties assume a linear decline in efficiency. If your panel degrades faster than expected, proving it’s a manufacturing issue can be challenging.
Important points to consider:
- Guaranteed power output: Pay close attention to the percentage of original output guaranteed after the warranty period. A higher percentage indicates a more reliable panel.
- Testing conditions: The guaranteed power output is often based on specific testing conditions. Real-world factors like weather and temperature can affect performance.
- Degradation rate: While most warranties assume linear degradation, some manufacturers offer a slower degradation rate.
2. Solar inverter warranty
The solar inverter is the heart of your solar system, converting direct current (DC) from the panels into usable alternating current (AC) for your home and business. Solar inverters usually come with separate warranties, often lasting 5 to 10 years, depending on the manufacturer. Ensure the solar inverter warranty aligns with or exceeds the labour warranty for a comprehensive safety net.

3. Installation warranty (Solar installer's warranty)
The installation warranty, provided by the company installing your solar system, safeguards against issues arising from faulty installation. This warranty typically lasts 5 to 10 years, depending on the solar installer.
Here’s what a solar installation warranty generally covers:
- Faulty workmanship: The warranty ensures the solar installer will rectify the issue if the solar panels are not installed correctly, leading to malfunctions or safety hazards.
- Electrical components: The warranty might cover faulty electrical components associated with the solar system installation, such as inverters and wiring.
- System leaks: Some warranties cover leaks in the system’s piping or connections.
Important points to consider:
- Warranty duration: A longer installation warranty indicates the solar installer’s confidence in their workmanship.
- Scope of coverage: Clearly understand what’s covered by the warranty and what isn’t.
- Installer reputation: Choose a reputable solar installer with a history of quality work and honouring warranties.
The importance of a reputable solar installer
The quality of the installation significantly impacts your solar system’s performance and longevity. Choosing a reputable Solar Accreditation Australia (SAA) approved solar installer in Australia is vital. SAA approval signifies the company adheres to strict industry standards and best practices. Reputable solar installers typically offer robust solar warranty packages encompassing product and installation warranties.

Understanding the solar warranty details
While the concept of solar panel warranties seems straightforward, delving deeper into the details is crucial. Here are some key aspects to consider:
- Warranty terms and conditions: Meticulously examine the warranty documents the manufacturer and installer provided. These documents outline the specific circumstances covered under the warranty, exclusions, and the claims process. Look for details like:
- What constitutes a defect?
- Are there limitations on power output degradation under the performance warranty?
- What is the process for filing a warranty claim?
- Are there any limitations on labour costs associated with repairs or replacements?
- Power output tolerance: Solar panels are not 100% efficient in converting sunlight to electricity. Manufacturers specify a power output tolerance range (usually +/- 3%), indicating a slight variation from the rated output. This tolerance is not covered under the warranty.
- Degradation rate: Solar panels naturally degrade in efficiency over time. The performance warranty specifies the guaranteed minimum output after a specific period (usually 25 years). Understanding the expected degradation rate helps manage expectations for long-term power generation.
- External factors: Most warranties exclude damage caused by external factors like hail, storms, or improper maintenance. It’s crucial to have a separate insurance policy to cover these eventualities.
Maximising your solar panel warranty benefits
- Request a comprehensive solar warranty guide from your solar installer. This document should clearly outline the specifics of each warranty (product, performance, installation) offered for your chosen system.
- Ensure proper maintenance of your solar panels. As the manufacturer recommends, regular cleaning and professional inspections can help maintain optimal performance and extend lifespan.
- Keep detailed records. Maintain copies of your warranty documents, including solar installation receipts and maintenance logs. This paperwork will be crucial if you ever need to make a warranty claim.
Maximising your solar investment: Tips for choosing the right warranty
- Prioritise reputable manufacturers: Opt for solar panels from established brands with a proven track record and a history of honouring warranties.
- Don’t just focus on the length of the warranty. While a longer warranty is generally better, the details of what’s covered are equally important. Carefully read and understand the terms and conditions of each warranty before finalising your solar purchase.
- Don’t solely focus on price: While cost is a significant factor, prioritise warranties with comprehensive coverage and extended durations. A slightly higher upfront cost can be offset by peace of mind and potential savings in case of future repairs or replacements.
- Compare warranty offerings from different retailers. Solar warranties can vary between companies. Feel free to ask potential solar retailers for detailed information on their warranty packages.
- Register your warranties. Most solar warranties require registration within a specific timeframe after solar installation. Ensure you register your warranties promptly to activate coverage.
