First year degradation of AKCOME HJT Modules is 1%, annual degradation is -0.25%. HJT modules can guarantee power generation rate of no less than 93% in 25 years, while TopCon and PERC are 89.4% and 87.2% respectively.
AKCOME HJT Modules adopts non-destructive cutting process to ensure the smooth cutting surface of the cell, without thermal-affected area, and no loss of current. While conventional cutting surface is rough, with heat affected area of 80-120μm.
HJT modules adopt the production technology of low-temperature ribbon and low-temperature flux, granting reliability and performance comparable to that of PERC.
The front and back sides of AKCOME HJT modules are encapsulated by TCO conductive film. Under high voltage and bias conditions, there is no insulating layer that accumulates charges, therefore PID phenomenon is avoided.
Compared with other types of solar modules, HJT modules with low temperature coefficient have less power loss and more stable power generation performance in high temperature environments.
The back radiation gain depends on the reflectivity of the ground surface and the installation mode of the module, etc. The HJT module benefits from higher bifacial power generation coefficient. The larger the radiation received by the back surface, the higher the power generation gain.
