SDN unveils 595 W solar module with 21.28% efficiency – pv magazine International

SDN, a South Korean provider of PV modules and marine propulsion programs, has unveiled a brand new glass-glass bifacial module line with energy outputs as much as 595 W.

The brand new SunDay 10+ modules have 144 monocrystalline half-cut cells based mostly on M1o wafers and busbar expertise. SDN claims that they’re at the moment the most important photo voltaic module produced in South Korea.

The producer gives 4 variations of panels, with nominal energy rankings of 580 W to 595 W, and energy conversion efficiencies from 20.75% to 21.28%. The open-circuit voltage is between 53.42 V and 53.95 V and the short-circuit present is between 13.8 A and 13.99 A.

The panels measure 2,465 mm x 1,134 mm x 35 mm and weigh 35.5 kg. They’re constructed with 2 mm tempered anti-reflective glass and aluminum alloy frames. In addition they function an IP68 enclosure and a most system voltage of 1,500 V. The panels have a temperature coefficient of -0.40% per diploma Celsius and an operational temperature from -40 C to 85 C.

New merchandise include a 12-year guarantee and a 30-year efficiency guarantee. The degradation within the first yr is alleged to be 2.0% and the 30-year finish energy output is assured to be at least 83.5% of the nominal output energy.

SDN operates a panel manufacturing unit in Gwangju, South Korea. It additionally plans to construct a 1 GW manufacturing facility in Gwangju that can produce photo voltaic panels based mostly on tunnel oxide passivated contacts (TOPCon) expertise, in addition to modules with non-specific tandem expertise.

The corporate is lively within the distributed technology PV section and has a big photo voltaic venture growth. It’s constructing photo voltaic arrays in Bulgaria, Japan and South Korea. Its shipbuilding division additionally provides outboard motors for fishing and pleasure boats.
