Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a photovoltaic power generation device. Background Art

[0002] A photovoltaic power generation device is a device that uses solar energy to generate electricity. It is mainly composed of photovoltaic panels (solar panels), inverters, support systems, etc. Its working principle is to directly convert sunlight into electrical energy through the photovoltaic effect. The semiconductor material (such as silicon) in the photovoltaic panel absorbs photons to generate electron-hole pairs and form an electric current.

[0003] Photovoltaic power generation devices rely on weather conditions. In severe weather such as hail, hail may directly smash or damage the panel. Even if the panel is not completely damaged, surface damage will reduce light absorption efficiency, affect power generation efficiency, and increase maintenance costs. Therefore, those skilled in the art provide a photovoltaic power generation device to solve the problems raised in the above background technology. Summary of the invention

By adjusting the angle of the photovoltaic bracket 201, the photovoltaic panel 202 is always facing the sun at the best angle, maximizing the absorption efficiency of sunlight and increasing the power generation. When hail weather is detected, the motor 301 rotates in the opposite direction, and the drive structure is driven by the motor 301. The structure 300 makes the photovoltaic bracket 201 flip over.
