About TDG Solar

TDG Solar's main claim to fame was to have been the first company to bring AC solar panels to Australia.

Company Info

TDG Holdings is a China-based multinational company established in 1984.

These days, TDG is involved in Special Equipment Manufacturing and Installation, and Electronic Materials Manufacturing, and also has a strategic investment arm. But it also had a division focusing on solar panel manufacturing some years ago. Exactly when or why it ceased producing modules isn't clear, but the TDG Solar website disappeared sometime around 2016/17 so far as we can tell.

TDG Solar Panels In Australia

TDG had a bunch of panels available in Australia at one point, from 180 W capacity to 305 W. A model worth noting was the TDG AC module, which was a 250 W monocrystalline solar panel integrated with a microinverter supplied by APS. 

A 5kW solar array consisting of these AC modules was installed at the  Desert Knowledge Australia Solar Centre (DKASC) located in Alice Springs; a demonstration facility for solar PV technologies. Those panels were installed in 2013 and still operating as at the middle of 2025.

TDG Solar also produced conventional monocrystalline panels in the 250 W to 260 W range.

Warranty Details

For its AC modules, TDG Solar offered 12-year module product warranty, 25-year warranty on power output, and 25-year micro-inverter product warranty. For the conventional panels, it was a 12-year warranty on materials and workmanship, plus a 30-year performance warranty. Given the timeframe it was operating, some TDG solar panels installed in Australia may still be covered by product warranty — you should contact the company that supplied and installed them if you're having problems. If they aren't around any more, try your luck with TDG Holdings' headquarters.
