Chinese solar module manufacturer Lians Technology has launched a heterojunction (HJT) solar module with multi-cut shingled cell design for residential and commercial rooftop PV systems.
The module relies on large-format HJT cells, a shingled design to reduce inactive spacing and front-side metallization losses by overlapping narrow cell strips and a zero busbar (0BB) architecture to improve current collection and reduce silver consumption. “Lians’ advanced multi-cut shingled structure optimizes current transmission paths and reduces electrical losses, enabling a 15W–20W increase in front-side power output, enhanced rear-side energy yield, and further reduction in levelized cost of energy (LCOE),” the company said in a statement.
The Venus Pro module is built with 102 multi-cut HJT cell strips derived from 210 mm wafers, each measuring 210 mm × 52.5 mm, and arranged in a 12 × 17 cell configuration. It measures 1,762 mm × 1,303 mm × 30 mm, with a surface area of approximately 2.3 m², and weighs 26 kg. It is available with an aluminum alloy or composite material frame and uses 2.0 mm front glass and 1.6 mm rear glass.
The new product is available in eight versions with power outputs ranging from 530 W to 565 W and offer power conversion efficiencies of 23.08% to 24.61%. Its open-circuit voltage is specified at 38.13 V to 38.96 V, while the short-circuit current ranges from 16.91 A to 17.20 A. It supports a maximum system voltage of 1,500 V DC and a maximum series fuse rating of 35 A.
The module has a temperature coefficient of temperature coefficient of −0.24%/C and is designed to operate in temperatures ranging from −40 C to 85 C. For mechanical performance, the Venus Pro series is certified according to relevant IEC standards and carries a TÜV SÜD Class II safety rating. The dual-glass construction is rated to withstand a front-side snow load of 5,400 Pa and a rear-side wind load of 2,400 Pa.
The Venus Pro modules come with a 15-year product warranty and a 30-year linear power warranty. Lians specifies first-year degradation below 1%, followed by annual degradation of no more than 0.32% from the second through the 30th year, ensuring a minimum retained power output of 89.75% after 30 years.
“Lians has achieved a significant milestone by becoming the world’s first HJT multi-cut shingled module manufacturer to receive both TÜV Rheinland and CE certifications, marking international recognition of its technological innovation, product reliability, and commercial application capabilities,” the manufacturer said.
Lians currently operates manufacturing facilities in China’s Sichuan and Jiangsu provinces, with a combined HJT production capacity of 8.8 GW, according to its own figures.
