How Do Solar Panel Warranties Work

Power Production Warranties

Solar panel warranties are an important part of the solar industry. They ensure that consumers are getting what they expect from their solar panels and that manufacturers are held accountable for any defects. We want to explore how solar panel warranties work in Australia while also looking at some of the key terms and conditions that are often found in these warranties.

Often shortened to PG, a production guarantee is offered to ensure that your solar system will produce a minimum amount of power over a given period of time. In Australia, most solar panel manufacturers offer a production warranty of between 15 and 25 years. This means that they guarantee their panels will produce a certain amount of power each year, typically around 90% of the original output. 

However, it’s important to note that these warranties only cover the panels themselves and not the inverter or other components in your system. Additionally, many warranties require you to have your system regularly serviced in order to maintain its validity. 

What does this mean? Well, you shouldn’t notice that power generation drops below 50% after just one year. To maintain competitiveness and high quality in the industry, manufacturers are forced to keep their panels working efficiently thanks to this warranty. 

In addition to production guarantees, most solar panel manufacturers also offer workmanship warranties. These are designed to protect against any errors made during the installation process and typically last for between one and five years. Once again, this ensures a high quality of service in the industry. If you find damage after just a few months, you’re protected. 

Monitoring Your System Output 

How do you monitor the output of your solar panel system? Here in Australia, there are a couple of ways. The first is to keep an eye on your electricity bills. If you’ve installed solar panels, you should see a decrease in the amount you’re paying each quarter. This is because you’re generating your own power and using less from the grid; the less you rely on the grid, the lower your energy bills should be each month. 

You can also monitor your system output directly by installing a meter that measures how much electricity your system is producing. This is a great way to get real-time feedback on how efficient your solar panels are and whether they need to be cleaned or repaired; you essentially see as output fluctuates over time. 

Solar panels are a great investment for any homeowner or business owner looking to reduce their energy costs. Thanks to government incentives and manufacturer warranties, they are becoming more affordable than ever and are presented as a strong investment in 2022. 


With this, you have a basic overview of how Solar panel warranties from installers work in Australia. Remember to do your research before purchase, as different manufacturers will offer different terms and conditions. Furthermore, always keep your system regularly serviced to protect the warranty and spot problems early.
