SEG Solar claims their new panels have a temperature coefficient of -0.30% per Celsius. They come with a 30-year power output guarantee worth 87.4% of the initial yield.
SEG Solar (SEG) has introduced a new solar module using n-type tunnel oxide passivated contact (TOPcon) technology.
Alpine N modules have 210 mm n-type TOPCon cells and are intended for ultra-large power plants.
“Using SMBB technology, the modules reduce internal electrical losses and enhance optical utilization. The non-destructive cutting process minimizes damage to solar cells, lowering the risk of hidden cracks and improving manufacturing yield,” the company said in a statement.
“The design includes a small gap between cells, reducing the distance from 2mm to 0.6mm, resulting in a 0.2-0.3% increase in module efficiency.”
SEG Solar offers four versions of the panels, with power outputs ranging from 685 W to 700 W. The efficiency ratings range from 22.05% and 22.53%. The open-circuit voltage is from 47.30 V to 47.90 V, while the short-circuit current is between 18.34 A and 18.49 A. The maximum system voltage is 1,500 volts.
The panels are 2,384 mm x 1,303 mm x 33 mm and weigh 338.5 kg. They also have an IP68 enclosure with 2 mm semi-tempered glass. They feature a temperature coefficient of -0.30% per degree Celsius and an operating temperature range of -40 to 85 degrees Celsius.
The new items come with a 30-year linear power output guarantee and a 15-year product warranty. The deterioration in the first year is reportedly 1.0%. The 30-year-end power output is guaranteed to be at least 87.4% of the nominal output power.
SEG Solar presently manufactures its panels in factories in Vietnam and Indonesia. In addition, it plans to build a 2 GW TOPCon module production plant in Houston, Texas.
