Suntech is one of the world’s oldest solar panel manufacturers, founded in 2001 in Wuxi, China. Long before Jinko, Trina and Canadian Solar became household names in Australia, Suntech was pioneering the early Australian solar market — giving the brand an unusual combination of genuine heritage and ongoing relevance in 2025.
Suntech panels are known for two things that don’t always go together: physical toughness and sleek aesthetics. Their high-strength aluminium alloy frame design provides exceptional resistance to structural twisting and wind loads — a meaningful advantage for South Australian rooftops exposed to the Adelaide Hills winds or coastal conditions. At the same time, their all-black Ultra V Bifacial All-Black module delivers one of the sharpest-looking installations available in the mid-range price bracket.
Suntech doesn’t market itself aggressively in Australia, which is partly why it’s underrated. Installers who work with Suntech regularly tend to be loyal to the brand precisely because the panels perform reliably without drama.
First Step Solar key takeaway
Underrated durability. Great if physical strength against structural twisting or wind loads is required, alongside sleek aesthetics. A solid mid-range choice for South Australian homes on exposed or coastal sites.

Funny enough, not in Canada, but in China, Brazil and Vietnam.
Founded in 2001 and operating in Australia since 2011.
Being a fantastic middle of the road panel, you really can't go wrong with Canadian, not the cheapest but not the most expensive, you won't have any issues with this panel.
Great news you don't need to fly to Canada, they have an office and warehouses right here in Australia, making it easy to get in touch if you ever need to.
