SDN has evolved new bifacial solar modules based on M10 wafers. According to the manufacturer, the new products attribute a power conversion efficiency of 21.46 percent and are the world’s most efficient floating PV panels.

SDN, a South Korean supplier of PV modules and marine propulsion systems, has revealed a new glass-glass bifacial module line for applications in floating PV projects.

The new SunDay 10+ Wave modules attribute 144 monocrystalline half-cut cells based on M10 wafers and busbar technology.

The developer offers three versions of the panels, with nominal power ratings of 590 W to 600 W, and power conversion efficiencies ranging from 21.11 percent to 21.46 percent.

The open-circuit voltage is between 53.79 V and 54.11 V and the short-circuit current is between 13.92 A and 14.05 A.

The panels measure 2,465 mm x 1,134 mm x 35 mm and weigh 35.9 kg. They are constructed with 2 mm tempered anti-reflective glass and aluminum alloy frames. They also feature an IP68 enclosure with a maximum system voltage of 1,500 V. The panels have a temperature coefficient of -0.40 percent per degree Celsius and an operational temperature ranging from -40 C to 85 C.

The new products come with a 12-year warranty and a 30-year performance warranty. The degradation in the first year is apparently 2.0 percent and the 30-year end power output is ascertained to be no less than 83.5 percent of the nominal output power.

The company also proposes to build a 1 GW manufacturing amenity in Gwangju that will develop solar panels based on tunnel oxide passivated contacts (TOPCon) technology and modules facilitating an unspecified tandem technology.

The company deals in the distributed-generation PV segment and huge-scale solar project development. It has built solar arrays in Bulgaria, Japan and South Korea.
