technical field

The invention relates to a folding solar photovoltaic panel fixing device, which belongs to the technical field of solar photovoltaic power generation systems.

Background technique

With the economic development of countries all over the world and the acceleration of industrialization and urbanization, people's demand for energy is increasing. At the same time, the use of a large number of chemical fuels has led to a rapid shortage of energy and increasingly prominent environmental pollution. In recent years, the current situation of global warming and air pollution has attracted people's attention. Countries all over the world advocate the development and application of new energy sources to reduce the impact of human life on the natural environment, and solar energy is one of them. It is a green and environmentally friendly new energy, inexhaustible and inexhaustible. At present, solar energy products have been used in aerospace and civilian applications. With the in-depth development of photovoltaic power generation technology and the promulgation of relevant national policies, solar energy products will definitely be favored by people in the near future.

Generally known solar energy vehicles (automobiles, boats, etc.) and solar roofs directly lay solar photovoltaic panels on the vehicles or roofs, and utilize sunlight to generate electricity during the day to provide part of the energy. However, generally this kind of power generation device cannot be disassembled and the installation angle of the photovoltaic panel cannot be adjusted. In this way, the solar photovoltaic panel is subjected to "wind and rain" without generating power at night or in severe weather such as storms, and the service life of the photovoltaic panel is greatly reduced. In the entire photovoltaic power generation system, the solar photovoltaic panel is the most critical component, its cost is the highest, and its photoelectric conversion efficiency directly affects the efficiency of the entire power generation system.

In addition, as automobile products gradually enter thousands of households, people increasingly favor self-driving travel when they go out for travel and leisure on sunny days. Generally, the battery on a car is only enough to maintain the power required for driving, but if it can be carried with the car A solar photovoltaic panel conveniently installed in the outskirts provides power for activities, which will definitely bring greater convenience to travel. During the day, the solar photovoltaic panel converts solar energy into electric energy under the regulation of the controller to directly supply electrical equipment for picnics or store the electric energy in the car battery, and the battery can be properly used for lighting at night.

At the same time, the installation of solar photovoltaic panels requires consideration of the latitude of the installation site and the influence of the season during installation on the installation angle, and generally requires professionals to measure and install. Since the sun's altitude angle will change when the season changes, it is necessary to adjust the installation angle of the solar photovoltaic panel from time to time to keep it under direct sunlight, which is difficult for ordinary home users to do.

Therefore, designing a solar photovoltaic panel fixing device that is easy to carry, easy to install and can precisely adjust the installation angle can greatly improve the current application range of solar energy and improve the service life and photoelectric conversion efficiency of solar products.
