Though monocrystalline silicon solar cell has high photoelectric conversion efficiency, monocrystalline silicon needs high cost. With the purpose of saving silicon materials, polycrystalline solar cells can be used to replace monocrystalline silicon solar cells.
We execute strict quality improvement management system and data control system in the production of polycrystalline solar cells to ensure their stability and reliability.

Features and Quality Control
1. In order to ensure high efficiency, this multicrystalline silicone solar
cell is designed with isotropy etched surface.
2. Low reverse current, high shunting resistance and dependability.
3. Aiming to ensure the quality of our multicrystalline silicon solar cell,
we offer proper incoming inspection, production quality controls, outgoing
inspections and packaging checking, etc.
4. 100% checked for reverse current and visual appearance
5. Small light-induced degradation
6. Calibration by Fraunhofer ISE
