Shinsung E&G releases 650 W TOPCon modules for ground and floating use
Shinsung E&G has introduced two series of n-type TOPCon bifacial modules rated at up to 650 W, designed for ground-mounted and floating or agrivoltaic installations. The new products feature efficiencies up to 23.25% and are supported by the company’s recently expanded 600 MW production capacity in South Korea.
According to pv magazine, Shinsung E&G has launched two new n-type TOPCon bifacial solar module series intended for ground and floating installations. The manufacturer indicates that these series provide nominal power ratings of 640 W, 645 W, and 650 W. As noted by pv magazine, the new modules achieve conversion efficiencies between 22.89% and 23.25% when measured under standard test conditions.
Technical specifications
Shinsung E&G has categorized its latest product range into two separate lines defined by their mounting method. The SS-JM-TK series is designed for ground-based setups, whereas the SS-JM-TN series is intended for floating photovoltaic and agrivoltaic uses. Each line incorporates 156 bifacial monocrystalline solar cells. The top-tier SS-JM650TK unit generates 650 W of power at a 23.25% conversion efficiency. Key electrical metrics for this model consist of a 55.71 V open-circuit voltage and a 14.52 A short-circuit current.
Ground-fixed panels span 2,465 mm by 1,134 mm and are 30 mm thick, while the floating and agrivoltaic versions have a 35 mm depth. Both types carry a weight of 33.5 kg. Built with a dual-glass structure, they employ 2.0 mm heat-strengthened glass alongside an anodized aluminum frame. To shield against dust and water, an IP68-certified junction box is fitted. These modules support a peak system voltage of 1,500 V and function effectively across a temperature span from -40 C to 85 C.
Performance and durability
Shinsung E&G’s new modules demonstrate distinct thermal and mechanical profiles depending on their intended installation. The temperature coefficient, which indicates how much power output drops as cell temperature rises, is lower for the floating and agrivoltaic series than for ground-mounted units. Mechanical load ratings also differ, with the floating and agrivoltaic modules rated for equal front and rear pressure, whereas ground-mounted units face higher front-side loads.
| Feature | Ground-mounted (SS-JM-TK) | Floating/Agrivoltaic (SS-JM-TN) |
|---|---|---|
| Temperature Coefficient | -0.34%/°C | -0.29%/°C |
| Front Mechanical Load | 5,400 Pa | 5,400 Pa |
| Rear Mechanical Load | 2,400 Pa | 5,400 Pa |
The company provides a 12-year product warranty and a 30-year performance guarantee. Under the performance guarantee, modules are rated to retain 99% of their initial power output after the first year, with an annual degradation rate of 0.4%. After 30 years, the guaranteed output remains at 87.4% of the initial rating.
Production capacity
In August, Shinsung E&G commenced operations on a fresh 350 MW line at its Gimje plant in South Korea. This addition elevates the site's aggregate output to 600 MW. The new capacity is dedicated to future Saemangeum initiatives, which consist of an 80 MW ground-based array, a 74 MW development, and a 300 MW floating system.
