Product Introduction








Product Details Show


tempered glass
- Low iron tempered embossed glass.
- 3.2mm thickness, enhance the impact resistance of modules.
- Self- cleaning function.
- The bending strength is 3-5 times that of ordinary glass.
EVA film
- Enhance the light transmission of the components.
- The cells are packaged to prevent the external environment from affecting the electrical performance of the cells.
- Bonding solar cells, tempered glass, TPT together, with a certain bond strength.




9BB mono solar cell
Assembled with 9BB PERC cells, the half-cell configuration of the modules offers the advantages of higher power output, better
temperature-dependent performance, reduced shading effect on the energy generation, lower risk of hot spot, as well as enhanced
tolerance for mechanical loading.
TPT back sheet
- High pressure resistance and high insulation.
- Shockproof and can effectively protect the cells from breaking.
- Good weather resistance, UV-resistant aging ≥25 years.




Aluminum Alloy Frame
- Silver and black color frame are optional.
- Strong corrosion and oxidation resistance.
- Strong strength and firmness.
- Easy to transport and install, even if the surface is scratched, it will not oxidize and will not affect performance.
