California-based SEG Solar says its new panels have a temperature coefficient of -0.30% per degree Celsius. They have a 30-year power guarantee, which is 87.4% of the original output.
SEG Solar offers four versions of the panels with powers ranging from 565 W to 580 W. Efficiency ratings range from 21.87% to 22.45%. The breakdown 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 dimensions of the panels are 2,268 mm x 1,134 mm x 30 mm and the weight is 32.0 kg. They also have IP68 housing and 2 mm semi-hardened glass. They have a temperature coefficient -0.30% per degree Celsius and operating temperature -40 C to 85 C.
The new products have a 30-year linear power warranty and a 15-year product warranty. First year decay is claimed to be 1.0%. The final output of 30 years is guaranteed to be at least 87.4% of the nominal output output.
Currently, the manufacturer manufactures its panels in factories in Vietnam and Indonesia.
