Things to consider when choosing solar panels

Solar modules are one of the most critical parts of a solar installation. Thus, selecting the right brand and solar panel type for your solar project is very important as it will determine the output and efficiency of your system.

The best solar panels in Australia need to be installed in compliance with the CEC standards to offer the best results. The best angle and direction also play a key role in attaining optimal yield from the system.

You cannot just follow what the salespeople suggest. You must do your own research and comparison between different solar panel brands to reach the right decision for your solar. There are some vital points that you should consider when buying solar panels, which we shall discuss here.

Things to consider when buying solar panels

1) Efficiency

What is solar panel efficiency? Solar panel efficiency is the measure of the ability of the solar modules to convert the sunlight that it receives into electricity. For instance, if a solar panel converts half of the sunlight that it absorbs to electrical energy, its efficiency would be 50%.

Solar panel efficiency usually ranges between 15% to 21%. Panels with higher efficiency are capable of producing more watts of energy per square meter of the PV module. Therefore, the higher the efficiency, the higher its price too.

Solar panels with an efficiency of 15% are a good enough choice. However, if you want to go for the latest in PV technology, and very high-efficiency panels, you must prepare to pay a little more.

Trina solar panels offer up to 20.4% efficiency while Jinko solar panels offer a maximum efficiency of 21.16%. Risen energy solar panels are another brand with a higher efficiency rating of 21.3%.

2) Temperature Coefficient

Solar panels do get hot during operation. As the temperature rises, production is reduced. A good temperature coefficient rating means that the panel can perform well and continue to generate optimally at high temperatures.

3) Voltage Rating

Voltage alters during operation in solar cells and the panels must be rated to 100V DC minimum for safety reasons.

4) Manufacturing Country

All the solar products you buy in Australia may not be made here. In fact, some of the best solar panels across the globe are made in China. Therefore, do not go after the manufacturing country but without bias chase products with high quality and trustworthy performance. You can read reviews posted by Australians after using solar products for many months to determine whether a panel brand is reliable or not.

5) Cost

When comparing costs between various solar panels, do not blindly go for the lowest prices. It may lead to poor performance and quality.

Compare the products based on the quality, warranty, and service you are getting for the price.

Be cautious of too-good-to-be-true cheap solar deals and never compromise on quality. Do compare various solar quotes to be certain that you are being offered quality components at genuine prices. And I shall repeat myself – Read reviews.

6) Warranty

You must look for a minimum 10-year product warranty on the panels you want. Please note that the product warranty covers material damage and is different from the 25-year performance warranty which only guarantees the performance efficiency of panels after 25 years.

When you go through online reviews you can find how reliable a company is in honouring its warranty claims through the experiences of other Australians with the brand.


There are some great options for solar panels in 2022 in the Australian solar market. Jinko Solar panels, Q-Cells, Trina solar panels, Risen energy solar panels, and Longi are among the best solar panels in Australia in 2022 which have superlative quality and performance along with great service in Australia.
