Photovoltaic panel capable of automatically adjusting light receiving angle based on thermal expansion and cold contraction principle

Abstract

The invention relates to the technical field of photovoltaic power generation, and discloses a photovoltaic panel capable of automatically adjusting a light receiving angle based on the principle of thermal expansion and cold contraction, and the photovoltaic panel comprises an arc-shaped plate, a fixed base is fixedly installed at the bottom end of the arc-shaped plate, and a rotating wheel is fixedly installed between the fixed base and the arc-shaped plate. According to the photovoltaic panel capable of automatically adjusting the light receiving angle based on the principle of thermal expansion and cold contraction, a groove body is filled with an expandable gas, the gas in the groove body is heated to expand, then a conductive ball is pushed to move downwards, the conductive ball carries negative charges to be connected with resistance wires, and the larger the number of the resistance wires connected into the circuit is, the higher the resistance in the circuit is, and the higherthe voltage is; the larger the magnetic force on a magnetic wheel is, the higher the magnetic force on the magnetic wheel drives a gear to rotate, the gear is matched with a connecting rod to drive asliding plate to slide on a guide rail rod, then angle adjustment can be conducted on the photovoltaic panel body on a fixed plate, and therefore the effect of conducting illumination angle adjustment through the thermal expansion and cold contraction principle is achieved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a photovoltaic panel that automatically adjusts the light-receiving angle based on the principle of thermal expansion and contraction. Background technique [0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect of the semiconductor interface. It is mainly composed of solar panels, controllers and inverters. The main components are composed of electronic components. After the solar cells are connected in series and packaged, a large-area solar cell module can be formed, and then a photovoltaic power generation device can be formed by cooperating with a power controller. [0003] At present, the utilization rate of photovoltaic power generation on the earth is still relatively low. On the one hand, the reason is that the conversion efficiency of photovoltaic power gener...
