Double-glass photovoltaic module

Abstract

The invention discloses a double-glass photovoltaic module and belongs to the field of photovoltaic technology. The double-glass photovoltaic module comprises a laminated piece (1), a first border (21), a second border (22) and a third border (23), wherein the first border (21), the second border (22) and the third border (23) are arranged on the long edges at the two sides and the short edge at one side of the laminated piece (1) respectively; and the two ends of the third border (23) are connected with one end of the first border (21) and one end of the second border (22) respectively. According to the double-glass photovoltaic module, by the adoption of the three-border design, the load capability requirement can be met; since no border on the lower side edge of the module blocks illumination of ground light to the back of the module after the module is installed on a photovoltaic power generation system, the back power generation capacity of the double-glass photovoltaic module cannot be influenced; and moreover, the double-glass photovoltaic module is not prone to dust accumulation or snow accumulation, the weight of the double-glass photovoltaic module can be reduced, and thecost of the double-glass photovoltaic module can be 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
