What is solar energy storage?

Solar energy storage is mainly used in solar products, such as our LED solar road stud lights, which require electricity. As a common green energy, solar energy needs to be stored before use. Silicon crystal panels are common energy storage media in solar streetlights.


In solar road studs, the solar panel is the main energy storage part. By absorbing sunlight, solar radiation energy is directly or indirectly converted into electrical energy through the photoelectric effect or photochemical effect. The main material of most solar panels is "silicon". ", but due to the high cost of production, there are still certain limitations in its general use. However, compared with ordinary batteries and rechargeable batteries, solar batteries are green products that are more energy-saving and environmentally friendly.

Solar energy storage technology is an important part of the smart grid and one of the key supporting technologies for the smart grid. A large number of renewable energy applications, especially wind power and solar photovoltaics, are random, intermittent, and volatile. Large-scale access will bring huge challenges to power grid peak regulation, operation control, and power supply quality. Energy storage technology can effectively improve the ability of the grid to accept clean energy and solve the security and stability problems brought about by large-scale clean energy access. For example, with the use of solar panels, the installation of road studs light on the road will no longer need to be connected to the mains to ensure lighting.
Considering the intermittent fluctuation of solar output power caused by light intensity and the randomness of energy consumption on the user side, it is an effective method to apply energy storage technology to solar-distributed combined cooling, heating, and power generation systems. Solve system instability and adjust the balance between energy supply and demand. According to the characteristics of energy storage medium, energy storage technology includes cold storage, heat storage, electricity storage, and other forms; according to the function of energy storage, the energy storage system can be applied to the energy supply side, user demand side, and energy transmission side. The process involves all aspects of the system. At the same time, from a functional point of view, the significance of energy storage technology also includes shifting peaks and filling valleys, alleviating the pressure on the power grid, and realizing energy cascade utilization. Therefore, rational use of energy storage technology is a prerequisite for the development of solar-distributed heat and power cogeneration.

Traditional fuel energy is decreasing day by day, and the damage to the environment is becoming more and more prominent. At the same time, there are still 2 billion people in the world who do not have a normal energy supply. At this time, the whole world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. Among them, solar energy has become the focus of people's attention due to its unique advantages. Abundant solar radiation energy is an important energy source, which is inexhaustible, non-polluting, cheap, and can be freely utilized by human beings.
