Formed laminate by above-mentioned glassy layer, backsheet layer, cell piece, encapsulating material layer and frame, and the order under upper is glassy layer, encapsulating material layer, cell piece, encapsulating material layer, backsheet layer.Laminate is all square with frame, scuncheon groove offer the installation being easy to laminate, its further groove inner surface is coated with protective layer, has certain protective effect to laminate, indirectly improves the service life of laminate, it is possible to decrease the maintenance cost in later stage.Additionally, above-mentioned U-shaped rhone is positioned at the top of laminate, under this photovoltaic module is placed on open-air atmosphere and time rainy, because photovoltaic module slant setting, therefore rainwater can slide down along laminate upper surface, it is then directed into U-shaped rhone, last again from apopore eliminating, the generation of seeping phenomenon can be avoided, reduction rainwater penetrating layer casting die affects it and works normally, improve the service life of this photovoltaic module, by top layer attached thereto for spot after ponding the most also can be avoided naturally dry in laminate, reduce the absorptivity to solar energy.
Higher than two ends in the middle part of described U-shaped rhone.
Apopore is positioned on the frame on U-shaped rhone two ends and identical with U-shaped rhone, is easy to ponding higher than two ends and discharges smoothly in the middle part of U-shaped rhone.
The lateral surface of described frame is pasted with rubber buffer.
Use above structure, Edge damaged can be avoided.
Protective layer is layer of silica gel or adhesive tape layer.
Layer of silica gel and adhesive tape layer are that material is easily bought in market, and additionally they also have certain elasticity, can protecting border.
Protective layer side and U-shaped rhone have arc transition.
Use above structure, facilitate rainwater to be flowed in rhone, it is to avoid the generation of seeping phenomenon.
Compared with prior art, the advantage of this anti-PID photovoltaic module have following some:
1, in this anti-PID photovoltaic module, the groove inner surface of scuncheon is coated with protective layer, laminate can play certain protective effect, indirectly improve the service life of laminate.
2, in this anti-PID photovoltaic module, the inner side of frame is provided with U-shaped rhone and apopore, it is simple to discharged by the ponding of laminate upper end, it is to avoid by top layer attached thereto for spot after ponding is naturally dry in laminate, reduce the absorptivity to solar energy.
3, in this anti-PID photovoltaic module, the lateral surface of frame is pasted with rubber buffer, and photovoltaic module is had protective effect, it is to avoid produces collision in carrying way, causes unnecessary loss.
