Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The technical terms related to the embodiment are described below, namely, a photovoltaic panel is a device capable of converting sunlight into electric energy, and mainly comprises photovoltaic cells. The working principle of the photovoltaic panel is that sunlight is converted into direct current through a photoelectric effect, and the photovoltaic panel is widely applied to a solar photovoltaic system. The photovoltaic panel comprises super white toughened glass, EVA, a power generation main body (such as a crystalline silicon solar cell or a thin film solar cell) and a backboard. These components work together to ensure that the photovoltaic panel can efficiently absorb sunlight and convert it into electrical energy. In the application field, photovoltaic panels are often used in roofs, floors, etc., and generate electricity by absorbing sunlight. Its advantages include environmental protection, regenerability and long service life, but also has some disadvantages such as certain requirements for installation environment and reduced power generation efficiency in overcast and rainy weather. Therefore, in selecting and installing photovoltaic panels, it is necessary to comprehensively consider advantages and disadvantages thereof and a specific installation environment.

The electric energy generated by photovoltaic power generation can be stored in various modes, and mainly comprises modes of battery energy storage, compressed air energy storage, water pump energy storage, super capacitor energy storage and the like. Battery energy storage is one of the most common photovoltaic energy storage modes at present, and commonly used batteries include lead-acid batteries, lithium ion batteries and the like. The lithium ion battery has the advantages of high energy density, light weight and the like, but has higher price. Lead acid batteries are inexpensive but have a low energy density and are susceptible to temperature. The compressed air energy storage is realized by compressing and storing residual voltage in the photovoltaic power generation of the daytime into the air storage, and then releasing and driving the turbine to generate power at night or in overcast and rainy days. The water pump is driven by the photovoltaic power generation power in the daytime to pump water from low to high, and the turbine is driven by the height difference of the reservoir to generate power at night or in overcast and rainy days, so that the energy storage efficiency and the cost are excellent. The super capacitor energy storage realizes energy storage by storing electric field energy, and has the advantages of high energy storage efficiency and capability of realizing high-speed charge and discharge.

The electric energy generated by the photovoltaic power generation can be used in a grid connection mode, and the photovoltaic power generation grid connection refers to the process that direct current generated by a solar cell array is converted into alternating current meeting the requirements of a commercial power grid through an inverter and then is connected into the public power grid for distribution, transmission and use. The grid-connected photovoltaic power generation system can convert direct current output by the solar cell array into alternating current with the same amplitude, same frequency and same phase as the voltage of the power grid, so that the grid-connected photovoltaic power generation system is connected with the power grid and transmits electric energy to the power grid. When the sunshine is sufficient, the photovoltaic power generation system supplies power to the alternating current load and simultaneously sends redundant electric energy to the power grid, and when the sunshine is insufficient, the electric energy can be obtained from the power grid for the load to use.

The power generation efficiency of the photovoltaic panel has close relation with the angle of the sun, the installation angle of the photovoltaic panel determines the incidence angle of the sunlight on the surface so as to influence the power generation efficiency, and ideally, if the sunlight vertically irradiates on the surface of the photovoltaic panel, the power generation efficiency is highest, however, in practical application, the sunlight is normally obliquely irradiated on the surface of the photovoltaic panel at a certain angle, and the maximum power generation efficiency cannot be always exerted.
