Best solar panels 2018 review.jpg

By combining years of experience in the solar industry and feedback from hundreds of solar professionals around Australia we have put together a list of the most popular solar modules from the leading manufacturers.

As highlighted in our guide to choosing a quality and efficient solar panel, when it comes to solar higher cost equals higher quality and performance. The higher quality modules from the leading manufacturers listed below have proven to out perform and outlast low-cost modules, with many of the lesser known 'cheap' manufacturers either going bankrupt or being de-listed from the Australian Clean Energy Council's list of approved suppliers.

Best Solar Panel Manufacturers

Here is our short list of the best quality and most reliable solar panel manufacturers supplying the Australian market based on company history, quality, real world performance and feedback from solar industry professionals.  Here we provide a quick summary of the top manufacturers warranty conditions plus the most popular panels offering the best quality, efficiency, innovation and value.

See the complete list and details of the many innovations being used to improve panel efficiency, reliability and performance in the complete solar panel technology review.

  • SunPower

Sunpower is the world leader in high efficiency solar cells and offer the best power output warranty at 92% retained capacity after 25 years on both the E series and  X series, plus a 25 year manfacturers warranty. Although the high performance IBC N-type cells used in Sunpower panels do come at a high price and are not widely available in Australia. In North America however Sunpower panels, in particular the E series are very popular and are one of the most trusted and highest performing panels available.

    Most Popular Solar Modules

    In addition to the best manufacturers there are a few models which are favorites among our specialists and many Australian installers due to a combination quality, efficiency, performance and value for money. These panels are also proving very popular in the US and much of Europe, in particular the range of modules from REC, LG and Q cells.

    LG NeON 2

    LG Neon modules use double sided cells to absorb light from the front and the rear of the module similar to PERC* cells, along with the LG Cello thin wire busbar technology to further improve efficiency. As of May 2018 LG Neon 2 panels are covered by a higher 25 year product warranty and higher performance warranty of 86% after 25 years. LG panels also have frames with very high wind load ratings which make them one of the strongest panels on the market. See full LG solar review here.

    REC panels use PERC* technology  and a unique split configuration which divides the panel into two sections, upper and lower which combine at a centre mounted junction box. This creates a panel which is much more efficient when partially shaded. The half size cells also increase efficiency and performance under most conditions.
