Double-glass photovoltaic module

Abstract

The invention discloses a double-glass photovoltaic module, and belongs to the technical field of the photovoltaic. The double-glass photovoltaic module comprises a laminating piece, a junction box and a first frame and a second frame arranged at two long sides of the laminating piece; the laminating piece comprises cover plate glass, a first package adhesive film, a battery string, a second package adhesive film and a backboard glass and a bus bar; a through hole is formed on the backboard glass, one end of the bus bar is connected with the battery string, the other end of the bus bar penetrates the through hole and is bent to form a bending side, thereby connecting with the junction box; the bending side of the bus bar does not contact with the edge of the through hole. The double-glassphotovoltaic module adopts the double-frame design, a loading capacity requirement can be satisfied, and the back generating capacity of the double-glass photovoltaic module cannot be affected since the a frame is inexistent at a module lower side to shield the light on the ground to irradiate to the module back after the double-glass photovoltaic module is arranged on the photovoltaic generationsystem, the double-glass photovoltaic module is hard to accumulate ash and snow, the weight of the double-glass photovoltaic module can be relieved, and the cost of the double-glass photovoltaic module is lowered.

Problems solved by technology

[0009] The first way: if figure 2 As shown, the segmented frame 2' is installed on the long sides of the laminate 1, and the component is installed on the longitudinal support 3' through the segmented frame 2', and the horizontal support 4' is not provided. This installation method The problem is that the load capacity of the double-sided double-glass module does not meet the requirements of the IEC (International Electrotechnical Commission, International Electrotechnical Commission) standard of 5400Pa

like Figure 4 As shown, the problem with this method is: since the components are usually installed at an angle to the ground, the lower frame of the component will block the light from the ground from reaching the back of the component, reducing the power generation; and the lower frame is also prone to dust accumulation , snow, dust, and snow accumulation will produce hot spots, which will not only reduce the power generation of the components, but also cause damage to the components to a certain extent
