Panasonic HIT® bringer det fulde energi potentiale til taget

Panasonic high efficiency solar cell is unique in structure. 

The crystalline silicon substrate is sandwhiched by the ultra-thin layers of amorphous silicon.
This amorphous silicon layer reduces the electrons lost on the surface resulting in high efficiency


Bifacial cell design

Heterojunction solar cell has a bifacial structure.
The cell even utilize the sunlight reflected back from the rear side material.





High performance at high temperature

Unlike conventional solar panels that suffer a radical drop in power generation efficiency at elevated surface temperature,
HIT maintains high efficiency even at high temperature.



Stress-controlled tab connetion

Typical tab interconnecting process is a soldering [temperature 800℃], but we believe the high thermal
stress could degrade the reliability of cell in longrun.
By reviewing process and material from the scratch, we created an original interconnecting process which
only requires less than 1/3 of temperature to ensure highest level reliability.
