Tindo Solar has launched new n-type TOPCon Walara G4P panels calling them Australia’s most powerful locally made rooftop modules
The lineup includes 440 W and 475 W CEC-certified panels, with improved efficiency and performance
Tindo says these panels were developed based on input from installer partners, using a 7-step Zero-Defect process
Australia’s only solar panel maker, Tindo Solar, has introduced new n-type TOPCon rooftop panels, claiming them as the ‘most powerful’ to date produced locally. The Walara G4P series comes in 2 high-efficiency variants.
The lineup features a 440 W standard panel and a 475 W all-black seamless model, both Clean Energy Council (CEC) certified. By using slightly larger cells and increasing busbars from 10 to 16, Tindo says it has improved overall module efficiency and performance.
Weighing 21 kg, the 440 W solar panel with 108 half cells offers up to 22.6% efficiency. Its dimensions are 1,722 x 1,133 x 35 mm.
The 475 W variant, with panel dimensions of 1,910 x 1,133 x 35 mm, weighs up to 23.5 kg and offers up to 21.9% efficiency with 120 half cells.
Tindo Solar CEO Richard Petterson shared that the panels are a product of the company’s in-house engineering and R&D effort, combined with input from installer partners, external research teams and the best technology from global supply chains.
Tindo is currently taking orders for the 440 W Walara panel through its selected distribution partners, while the 475 W variant will follow in September 2025. The manufacturer says its 575 W module is the one with the most power output produced domestically in the utility-scale segment.
The new Walara panels have been independently tested to withstand cyclones, hail, damp heat, and temperatures from -40˚C to 85˚C, according to Tindo. They are made using a 7-step Zero-Defect process, giving them a failure rate of just 1 in 200,000 – about 200 times better than the industry average.
Tindo is exploring the development of a high-performing and highly durable Australian TOPCon solar cell in collaboration with the University of New South Wales (see Asia Pacific Solar PV News Snippets: Tindo Solar & UNSW To Develop Australian TOPCon Solar Cell & More).
The Australian manufacturer recently secured AUD 34.5 million under the federal government’s Solar Sunshot initiative to expand its production capacity to 180 MW annually (see Australia Injects AUD 45.5 Million Into Solar Manufacturing Expansion).
