Shinsung E&G unveils 650 W bifacial TOPCon solar modules with 23.25% efficiency
Shinsung E&G launched bifacial TOPCon solar modules in ground-mounted and floating/agrivoltaic versions, with power outputs up to 650 W and efficiencies reaching 23.25%.
South Korea’s Shinsung E&G introduced two new bifacial solar module series using n-type TOPCon cell technology. The SS-JM-TK series targets ground-mounted installations, while the SS-JM-TN series is designed for floating PV and agrivoltaic projects. Each series offers three power variants—640 W, 645 W, and 650 W—with front-side efficiencies between 22.89% and 23.25% under standard test conditions.
The ground-mounted modules measure 2,465 mm × 1,134 mm × 30 mm and weigh 33.5 kg, with the SS-JM650TK delivering 650 W and 23.25% efficiency. Under bifacial nominal power irradiance conditions, these modules achieve 700 W to 710 W, with efficiencies up to 25.40%. The floating and agrivoltaic modules share the same dimensions but use a 35 mm frame, also weighing 33.5 kg and providing up to 650 W front-side power.
Under BNPI conditions, the floating and agrivoltaic series reaches 705 W to 717 W, with the highest-rated model achieving a bifacial-equivalent efficiency of 25.65%. Both series feature dual-glass construction with 2.0 mm heat-strengthened glass, an anodized aluminum frame, and an IP68 junction box with three bypass diodes, rated for operation from -40°C to 85°C.
Shinsung E&G provides a 12-year product warranty and a 30-year performance warranty, guaranteeing at least 99% of initial power after one year and 87.4% after 30 years. The company opened a 350 MW production line in August at its Gimje factory, expanding total capacity to 600 MW for projects including an 80 MW ground-mounted installation and a 300 MW floating solar facility.
