Description

Technical Field

[0001] The present invention relates to a photovoltaic panel power generation device, specifically an expandable and retractable structure for photovoltaic solar panel power generation. Background Technique

[0002] A solar photovoltaic panel refers to a facility that converts solar energy into direct current electricity using the photovoltaic effect of photovoltaic semiconductor materials. The core of a photovoltaic facility is a solar cell panel. Currently, the semiconductor materials used for power generation mainly include: monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, etc. In recent years, as various countries have been actively promoting the application of renewable energy, the development of the photovoltaic industry has been very rapid. Since the advent of solar cells, continuous progress in the materials and technologies used, as well as the development and maturity of the manufacturing industry, have driven the price of photovoltaic systems to become cheaper.

[0003] Existing photovoltaic solar power generation devices install a single whole photovoltaic solar panel through a bracket. The larger the area of the solar photovoltaic panel, the more solar energy can be converted. However, if the volume of a photovoltaic solar panel is made too large, it is not conducive to the transportation of the solar panel. Existing photovoltaic solar panels are all a single integral structure, and damage will be caused to the photovoltaic solar panel during the process of loading and transporting the vehicle. Therefore, it is necessary to design an expandable and retractable structure for photovoltaic solar panel power generation. Summary of the Invention

[0004] The purpose of the present invention is to provide an expandable and retractable structure for photovoltaic solar panel power generation to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:
