High efficiency top quality 250w yingli solar panel
- First-class production technology and packaging technology.
- Adopting the world’s leading technology of silicon and polycrystalline power, higher conversion efficiency.
- Beautiful, stable, easy to take down the anodic aluminum frame electric degrees and has a wind resistant, anti-snow function.
- After the minus reflection process of the battery surface, it increases the absorption rate.
- By the high transmittance, low iron tempered glass, antiaging of the EVA(polyethylene-vinyl acetate), high performance crystalline 6.silicon solar cells, good weather resistance TPT(fluoroplastics composite membrane) by pyramid, has a good weather resistance and anti-UV, hail, water-proof capacity.
- Built-in bypass diode inside the junction box, which could prevent the effects dark spots of local damage to cells.
