Why TOPCON Solar Panel Technology?

TOPCON stands for Tunnel oxide passivated contact (TOPCon) cell technology.
The 144-cell bifacial panel is available in power range from 550 W to 575 W and an efficiency of 21.4% to 22.4%. Its open-circuit voltage is between 50.2 V and 51.2 V and the short-circuit current is 13.87 A to 14.17 A.
The panel features a transparent backsheet on the rear side, weighing 28 kg with dimensions of 2,266 mm x 1,133 mm. It is built with 182 mm (M10), 16BB, half-cut cells.
The panel can be used with a maximum system voltage of 1,500 V. It has a temperature coefficient (Pmax) of -0.31% per degree C and an operational temperature ranging from -40 C to 85 C.
The panel comes with a 12-year product warranty and a 30-year performance warranty. The first-year degradation is 1%. The power output at the end of 30 years is guaranteed to be no less than 87.4% of the nominal output power.
