Chinese language photo voltaic module maker Bluesun has unveiled new residential photo voltaic panels primarily based on hybrid passivated again contact (HPBC) expertise.
The cell expertise is an extension of p-type interdigitated back-contact (IBC) expertise and reportedly combines the structural benefits of PERC, TOPCon, and IBC photo voltaic. Busbars and finger electrodes are positioned on the again aspect.
“This expertise eliminates the results of shading and improves daylight absorption price by roughly 2.27% in comparison with typical PERC modules,” the corporate stated in an announcement.
The BSM450M10-54NHS panels have an influence output of 450 W and an influence conversion effectivity of as much as 23.0%. The open-circuit voltage is 39.93 V and the short-circuit present is 14.45 A.
The brand new panels measure 1,722 mm x 1,134 mm x 30 mm and weigh 20.8 kg. Additionally they function a temperature coefficient of -0.29% per diploma Celsius.
They arrive with a 30-year efficiency guarantee and a 15-year product guarantee. The 30-year finish energy output is assured to be at least 86.9% of the nominal output energy.
