[0001] The utility model belongs to the technical field of photovoltaic panel efficiency enhancement, and particularly relates to a photovoltaic module efficiency enhancement device applied to a photovoltaic power station. Background Art

[0002] A photovoltaic module, also known as a solar panel, is a short name for a solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar light radiation energy into electrical energy. It is composed of multiple solar cells connected in series or parallel to generate the required voltage and current. How to reduce the cost of solar cells and improve the energy conversion efficiency of solar cells during photovoltaic module power generation is an important means for the industry to reduce the cost of photovoltaic power generation for many years.

[0003] Currently, when photovoltaic modules are installed, generally multiple photovoltaic modules are arranged neatly, with gaps left between adjacent photovoltaic modules. The photovoltaic modules cannot receive the sunlight scattered in the gaps, resulting in a reduction in solar energy conversion efficiency. Summary of the Utility Model

[0004] To solve the above problems, the utility model provides a photovoltaic module efficiency enhancement device applied to a photovoltaic power station, which reasonably utilizes the sunlight scattered between adjacent photovoltaic panels.

[0005] The utility model is realized through the following technical solutions.

[0006] A photovoltaic module efficiency enhancement device applied to a photovoltaic power station includes two vertically arranged vertical rods, which are distributed front and back. Horizontal crossbars are fixedly installed on both vertical rods. A light collecting component for concentrating sunlight onto the photovoltaic panel is arranged at the upper end of the vertical rod, and a light reflecting component for reflecting sunlight to the bottom of the photovoltaic panel is arranged at the right end of the crossbar.

[0007] Further, the light collecting component includes an airfoil-shaped plate. Both the front and rear ends of the airfoil-shaped plate are installed on the corresponding vertical rod through the first connecting rod. The airfoil-shaped plate is made of a light-transmitting material.

[0008] Further, the airfoil-shaped plate has an arched structure. The upper surface of the airfoil-shaped plate faces the right photovoltaic panel, and the lower surface of the airfoil-shaped plate faces the left photovoltaic panel.

[0009] Further, the light reflecting component includes a reflector. Both the front and rear ends of the reflector are installed on the corresponding crossbar through the second connecting rod. The reflector is located at the bottom of the photovoltaic panel.

[0010] Further, the cross-section of the reflector has a "U" - shaped structure with an upward opening.

[0011] Further, the width of the reflector is greater than the width of the photovoltaic panel.

[0012] Further, a reinforcing rod is horizontally fixed between the two vertical rods.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In the present utility model, the condensing component is installed between two photovoltaic panels through two vertical rods. Under the action of the condensing component, the sunlight between the two photovoltaic panels is refracted to the upper surface of the left photovoltaic panel. The reflecting component is installed at the bottom of the right photovoltaic panel through two cross rods. Under the action of the reflecting component, the sunlight scattered from the side of the photovoltaic panel is reflected to the lower surface of the photovoltaic panel, increasing the area of the photovoltaic panel receiving sunlight. The two cooperate with each other to improve the power generation efficiency of the photovoltaic panel. Description of the Drawings
