ET Solar - Solar Panel Reviews

About ET Solar

ET Solar is a Chinese panel manufacturer that was founded in 2005 that has shipped more than 7.2GW of modules since it kicked off.

Contact Information

While ET Solar did have an Australian office at one stage, it's no longer around. That means contacting their headquarters in China. 

At the time we updated this page in early 2025, the company's website was undergoing an upgrade and there was little information on it. The only contact points listed are two email addresses: [email protected] and [email protected].

Company Info

ET Solar is headquartered in Nanjing, China. After its founding in 2005, the following few years were pretty busy for the firm with setting up new manufacturing and presence outside of China. By 2010, the company claimed to have 1GW of annual module capacity. By 2013, that had grown to 2.5GW. 

As well as manufacturing panels, the firm also engaged in building utility-scale solar farms for various customers across the world.

ET Solar became a Chinese government-owned company in 2018 and soon after that, the flow of company news ceased - but it's certainly still around.

A search of the Australian Securities and Investments Commission (ASIC's) database revealed several ET Solar branded company names were deregistered here in 2024.

ET Solar Panels In Australia

ET Solar set up its Australia subsidiary in 2014, but it's not clear when it stopped operating here. It appears that as recently as early 2024, there were still several product lines available in Australia that were approved by the Clean Energy Council

• Elite Mono: (360W - 385W)
• Elite Poly: (340W - 345W)
• Elite Plus: (400W - 410W)

But as at early 2025, there are no ET Solar panels on the CEC's approved modules list. 

Warranty Information

ET Solar panels have a 10-year product warranty and 25 year performance warranty these days; the nature of the latter depending on the model.

If you have a warranty issue, your best bet is to contact the company that installed them. If that isn't successful for whatever reason (e.g. installer is no longer around), you could try to find the Australian importer of the panels - whoever imports the solar panels is responsible for their warranties. But if that was ET Solar, try contacting the company on the email addresses above - and good luck!
