The best solar panels in our past tests

At a glance: what we found in our solar panel tests up to 2019.

CHOICE partnered with the CSIRO from 2015 to 2019 to test solar panels from Opal, LG, JA Solar, Suntech and more. The results from those tests are summarised in this article.

As of 2022 we have since begun a new round of solar panel tests with a new partner, PV Lab Australia.

We also surveyed CHOICE members in 2018 about their home solar PV systems to find out about their experience with various solar technologies, solar installers and energy companies.

Which solar panels did best in the CSIRO tests?

Chris Barnes – solar expert

We recommended panels that score 80% or more. But the other solar panels in our test also performed well, scoring at least 75%.

Note that all these panels have long since been superseded by newer and better-performing models.

Previously tested solar panels in order of CHOICE score
JA Solar JAP6-60-255/3BB 82%
Tindo Karra-270 82%
Trina TSM-270PD05 82%
Jinko JKM270PP-60 81%
Winaico WST-285P6 80%
JA Solar JAM60S01-285/SC 78%
LG LG300S1C-A5 78%
Suntech STP300S-20/Wfm 77%
Opal QSA300M-60-S 76%
Yingli YL270P-29b 76%
Opal QSA270P-60-S 75%

What our members told us

We surveyed more than 1000 CHOICE members across Australia in 2018 about their experience buying and owning a solar system.

The most commonly owned solar panel brands were Suntech, Trina, LG, Jinko and Sunpower.

Although 33% reported having problems with their solar system, only 2% reported problems with the panels themselves.


In my current role I manage a range of product review projects for CHOICE. Most product reviews are done here in the CHOICE labs, but my focus is on those projects where we partner with external labs or data sources.  For some product types, CHOICE doesn't have the facilities to perform testing, and usually it wouldn't be practical or economic for us to build them. So we partner with other expert labs for some tests, including solar panels, electric heaters, air purifiers and detergents. For some other projects we make use of government energy registry data, including air conditioners and heat pump hot water systems. I also manage our testing services through our commercial arm, Test Research, and I'm CHOICE's NATA Authorised Representative for all matters relating to to our lab's formal accreditations. I'm involved with the standards committee for air conditioners. I often liaise with government and industry in areas such as product safety and regulation.  In over 20 years at CHOICE, I've had a variety of positions, writing content and managing lab teams for a wide range of products, including children's products, kitchen appliances, laundry appliances, garden power tools and more. My background is in science and technology. I have a science degree from the University of Sydney and I had a 15-year career in IT before joining CHOICE in 2004. CHOICE lets me exercise both sides of my brain; there's nothing I like better than diving into a stack of technical data and turning it into useful, consumer-friendly info for you, our members. (Though sampling pizza and scones from our oven testing is pretty nice, too.) You can find me on Twitter (X) and LinkedIn.
