Double-sided photovoltaic module and manufacturing method

Abstract

The invention discloses a double-sided photovoltaic module, which comprises a photovoltaic panel, the photovoltaic panel comprises a plurality of silicon wafers for double-sided photovoltaic power generation, the plurality of silicon wafers are connected in series, the silicon wafers are circular, and light-transmitting areas are formed among the plurality of silicon wafers; the support comprises a rigid frame, the photovoltaic panel is clamped and fixed in the rigid frame, the support is fixedly connected with a light reflecting plate, and the light reflecting plate is arranged on the backlight side of the photovoltaic panel so as to reflect sunlight reaching the light reflecting plate to the backlight side of the photovoltaic panel. According to the double-sided photovoltaic module disclosed by the invention, the circular silicon wafers are used for generating power, the circular silicon wafers are simple to manufacture, the photovoltaic panel formed by combining the plurality of circular silicon wafers forms a light-transmitting area, and the light-transmitting area is superior to that of a rectangular silicon wafer, so that the reflecting plate on the bracket receives more sunlight illumination; therefore, the back surface of the silicon wafer can receive more sunlight, and the generating capacity of the double-sided photovoltaic module is improved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a double-sided photovoltaic module and a manufacturing method. Background technique [0002] In recent years, my country's solar photovoltaic industry has developed rapidly and is showing great vitality. [0003] At present, in order to increase the power generation power of photovoltaic modules, photovoltaic modules with double-sided power generation and energy supply have been developed on the market. , to increase the power generation of photovoltaic modules. [0004] However, there are still some problems in the use of existing double-sided photovoltaic modules. The manufacturing cost of double-sided photovoltaic modules is significantly higher than that of single-sided photovoltaic modules. Compared with single-sided photovoltaic modules, the increased power generation of photovoltaic modules is not significant, so it is difficult for double-sided pho...

[0004] However, there are still some problems in the use of existing double-sided photovoltaic modules. The manufacturing cost of double-sided photovoltaic modules is significantly higher than that of single-sided photovoltaic modules. Compared with single-sided photovoltaic modules, the increased power generation of photovoltaic modules is not significant, so it is difficult for double-sided photovoltaic modules to be widely used
