Product Feature and Application
The half-cell technology reduces internal losses and hot spot effects by cutting standard solar cells into two halves, thereby improving module power and shading performance.
Lightweight design typically uses ultra-thin materials (such as chemically strengthened glass) to replace traditional glass, reducing module weight by more than 60%, making it suitable for load-constrained scenarios, such as mobile homes, lightweight roofs, or curved structures.
