Technical Field

[0002] In recent years, with the rapid development of the photovoltaic industry and the continuous advancement of related technical levels, bifacial photovoltaic modules have emerged to improve the power generation efficiency of photovoltaic power stations. Compared with traditional single-sided photovoltaic modules, bifacial photovoltaic modules make the original opaque back electrode into a transparent grid line, and through doping, the back of the silicon wafer in the photovoltaic module is made into a PN junction, so that both the front and back sides of the photovoltaic module can perform photoelectric conversion.

[0003] The traditional fixed double-column photovoltaic support structure mostly adopts a structural type of horizontal purlins and longitudinal diagonal beams, that is, the support purlins are arranged directly below the components, and the purlins are fixed on the support diagonal beams. The diagonal beams are fixed to the front and rear columns of the support through diagonal braces and hinges, and the front and rear columns of the support are fixed to the support foundation through foundation embedded parts.

[0004] When using this type of photovoltaic support structure, since the purlins are arranged directly below the photovoltaic modules, the back of the photovoltaic modules will be directly blocked, thereby affecting the area of ​​the back of the photovoltaic modules that receives reflected light and reducing the power generation of the system.
