This white mono solar panel is especially fit for the solar PV products. It is designed with the power and the photoelectric conversion efficiency ranging from 250W to 270W and 14.8% to 15.98%. The modular design allows the product being installed on the ground, roof and the surface of building or in the tracking system conveniently. Meanwhile, the professional PV glass with the thickness of 3.2mm is adopted by the product. Compared with the ordinary glass, this PV glass has low content of iron impurities and high transmittance up to 92%. It has excellent optical performance. Furthermore, the ultrahigh hardness can allow the PV glass resisting the external impact of general stress to protect the white mono solar panel effectively.
