SEG Solar has unveiled a new solar module based on n-type tunnel oxide passivated contact (TOPcon) technology. The Yukon 144-cell modules feature M10 (182 mm) N-type TOPCon cells and are designed for ultra-large power stations, it said.
SEG Solar is offering four versions of the panels, with power outputs ranging from 565 W to 580 W. The efficiency ratings range from 21.87% to 22.45%. The open-circuit voltage is between 51.50 V and 52.10 V and the short-circuit current is between 13.89 A and 14.07 A. The maximum system voltage is 1,500 V.
The panels measure 2,268 mm x 1,134 mm x 30 mm and weigh 32.0 kg. They also feature an IP68 enclosure and 2 mm semi-tempered glass. They have a temperature coefficient of -0.30% per degree Celsius and an operational temperature ranging from -40 C to 85 C.
The new products come with a 30-year linear power output guarantee and a 15-year product guarantee. The degradation in the first year is purportedly 1.0%. The 30-year end power output is guaranteed to be no less than 87.4% of the nominal output power.
The manufacturer currently produces its panels at factories in Vietnam and Indonesia.

Great to see the many advancements in solar panels….but we need the manufacturing to happen in Canada and the US.
Interesting article, and glad that technology is advancing and more manufacturers are being innovative but I thought that there were other company’s that had produced panels with Topcon efficiency of 24 and 25% ?
