SDN Co Ltd, a South Korean provider of PV modules and marine propulsion systems, recently began production of a new glass-glass bifacial module series with a power output of up 550 W at its factory in Gwangju, in southwestern Korea.
“We are also planning to launch the production of two new solar modules relying on M12 wafers with a nominal power of 590 W and 650 W, respectively, in the third quarter of this year,” the manufacturer said in a statement.
The new module, dubbed SunDay 10, uses 144 monocrystalline half-cut cells based on M1o wafers and busbar technology. It is available in three versions with nominal power of 540 W to 550 W and power conversion efficiency spanning from 20.89% to 21.28%. The open-circuit voltage is between 49.50 V and 49.80 V and the short-circuit current is between 13.85 A and 13.99 A.
The panel measures 2,279 mm x 1,134 mm x 35 mm and weighs 32.8 kg. It is built with 2 mm tempered anti-reflective glass and an aluminum alloy frame. It also features an IP68 enclosure and the maximum system voltage is 1,500 V. The panel has a temperature coefficient of -0.39% per degree Celsius and its operational temperature ranges from -40 C to 85 C.
The new product comes with a 30-year linear power output guarantee and a 10-year product guarantee. The degradation in the first year is purportedly 2.5% and 30-year end power output is guaranteed to be no less than 83.0% of the nominal output power.
SDN announced plans to start the new module production in September 2021. The company is also active in both the distributed generation and large-scale project development business. It has developed several solar parks across Bulgaria, Japan and its home country. Its shipbuilding division supplies outboard motors for fishing and leisure boats.

Why? Bigger size is more difficult to handle and more likely to get microcrack at least. Also after installation one has less clamps. What will happen during storms? rather go back to 1650x990x40 an focus om effecienty. In a university in the Netherlands they have reached 30%+ efficiency..
I totally agree with you
If these panels will be available on the market, what markets fo you they’ll reach, any chance in Europe?
