DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] The professional terms involved in the present embodiment are described as follows: the photovoltaic panel is a device capable of converting sunlight into electrical energy, mainly composed of photovoltaic cells. The working principle of the photovoltaic panel is to convert sunlight into direct current through the photoelectric effect, and it is widely used in solar photovoltaic systems. The components of the photovoltaic panel include super-white tempered glass, EVA, power generation main body (such as crystalline silicon solar cell or thin film solar cell) and back plate, etc. These components work together to ensure that the photovoltaic panel can effectively absorb sunlight and convert it into electrical energy. In terms of application scenarios, photovoltaic panels are often used in places such as rooftops and ground, generating electricity by absorbing sunlight. Its advantages include environmental protection, renewable and long service life, but at the same time, it also has some disadvantages, such as certain requirements for installation environment, and the power generation efficiency will decrease in rainy weather. Therefore, when selecting and installing photovoltaic panels, their advantages and disadvantages as well as the specific installation environment need to be considered comprehensively.

[0025] The electrical energy generated by photovoltaic power generation can be stored in various ways, mainly including battery energy storage, compressed air energy storage, water pump energy storage and super capacitor energy storage. Battery energy storage is one of the most common photovoltaic energy storage methods at present, and the commonly used batteries include lead-acid batteries, lithium ion batteries and the like. The lithium ion battery has the advantages of high energy density and light weight, but the price is relatively high. The lead-acid battery is cheap, but the energy density is low and is easily affected by temperature. The compressed air energy storage stores the excess electricity in photovoltaic power generation during the day into a gas storage by compression, and releases it at night or on rainy days to drive a turbine to generate electricity. The water pump energy storage drives a water pump to pump water from a low place to a high place during the day using photovoltaic power generation, and drives a turbine to generate electricity using the height difference of the reservoir at night or on rainy days; this method is excellent in energy storage efficiency and cost. The super capacitor energy storage stores energy by storing electric field energy, and has the advantages of high energy storage efficiency and can realize high-speed charging and discharging.

[0026] The electrical energy generated by photovoltaic power generation can also be used in parallel with the grid. Photovoltaic power generation parallel with the grid refers to the process of converting the direct current generated by a solar cell array into alternating current that meets the requirements of the power grid through an inverter, and then connecting it to the public power grid for distribution, transmission and use. The grid-connected photovoltaic power generation system can convert the direct current output by the solar cell array into alternating current with the same amplitude, frequency and phase as the grid voltage, realize connection with the grid and deliver electrical energy to the grid. When the sunlight is sufficient, the photovoltaic power generation system supplies power to the alternating current load while sending excess electrical energy to the grid; when the sunlight is insufficient, it can obtain electrical energy from the grid for the load.

[0027] The power generation efficiency of the photovoltaic panel is closely related to the angle of the sun; the installation angle of the photovoltaic panel determines the angle of incidence of sunlight on the surface, thereby affecting the power generation efficiency; in an ideal case, if the sunlight is perpendicular to the surface of the photovoltaic panel, the power generation efficiency is the highest; however, in actual application, the sunlight usually obliquely strikes the surface of the photovoltaic panel at a certain angle, and cannot always exert the maximum power generation efficiency.
