In this article, we will tell you the top five solar panel brands in Australia and discuss the factors that put these panels at the top of the list. 

The world of solar power systems is changing rapidly, and new brands and versions of solar panels are being introduced every day. Over the past decade, we have had hundreds of solar panel manufacturers enter the Australian solar market with hopes of earning a big name in the industry. But there are only a few manufacturers who have proven themselves to be one of the 5 top solar panel brands here in Australia.

These manufacturers have proven themselves as the top performer in various tests. All of these brands are CEC approved and popular among residential and commercial customers for their high-quality and undeniably great performance. 

How to determine the top 5 Solar Panel brands in Australia?

There are various factors that experts consider carefully before determining a solar panel manufacturer as one of the top solar panel manufacturers in Australia. These factors are:

  • Efficiency

The efficiency of a solar panel is a standard measurement that determines the rate at which a solar panel converts the sun’s energy into electricity. Solar panels manufacturers all over the world are spending thousands of dollars in research and development in order to produce a solar panel with the highest possible efficiency. 

If we look at the solar panels available to the world 10 years ago, we will see that the maximum output of solar panels was 100 watts back then. But in today’s date, there are a few manufacturers who successfully produced solar panels with a power output of 500 watts. Higher efficiency in solar panels means that your home will require a smaller number of panels. 

  • Product and Performance Warranty

When it comes to considering the factors of solar panels, one of the essential factors to consider is the product and performance warranty of the solar panels. In the majority of products in the world, the length and features of the warranty indicate to the durability and quality of the product. Similarly, in solar panels, the length of the product and performance warranty indicates the sustainability and quality of the solar panels. 

The product warranty of a solar panel covers the change of defective and replaceable parts in the solar panel manufacturing process. The performance warranty makes sure that the solar panel will still generate a certain percentage of the maximum energy output. 

In the solar industry, manufacturers typically offer a product warranty of 10 years and a performance warranty of 25 years. However, there are a few solar panel manufacturers who offer a product warranty of more than 10 years. 

  • Rate of Efficiency Degradation

As we discussed in the warranty section above, the efficiency reduces to a certain percentage by the end of the expected lifetime of the solar panel. After the first year of solar panel installation, the panels start to lose a small percentage of their working efficiency with each passing year. This percentage loss of the solar panel efficiency is known as the rate of degradation. 

The rate of degradation is a major factor to consider as it indicates the performance of the solar panel over the years. Manufacturers spend years trying to produce solar panels that have a very low rate of degradation. A low rate of degradation will ensure that the solar panels provide better performance for a longer period of time. 

  • Bloomberg Tier 1

The Bloomberg Tier 1 solar panel ranking usually works as an indicator in the solar markets that helps customers to identify high-quality solar panels. The Tier 1 ranking only refers to the marketability of the solar panel manufacturers. This helps the customers to understand whether the solar panel manufacturer will be in business for the upcoming 25 to 30 years or not. 

This is an essential factor to consider as this assures the customers that the business will be there to solve their problems and warranty claims. Even though the Tier 1 ranking does not assure the performance or the quality of the solar panels, it adds assurance to the warranty provided by the solar panel manufacturers. 


The five solar panel manufacturers we mentioned above have proven themselves deserving of the top rankings through their qualities, performance, and features. Experts conduct close research of the solar panels and thoroughly consider all the deciding factors before determining the top solar panels.
