Solar energy power accumulating system

Abstract

The invention relates to a solar energy power accumulating system, which is connected with at least one load unit and comprises a solar panel, an energy accumulating unit, a switch unit and a control unit. The solar panel is used for receiving solar energy and then converting the solar energy into direct current electric energy; the energy accumulating unit comprises at least one magnetic capacitor and used for accumulating the direct current electric energy; the switch unit is coupled between a solar battery and the energy accumulating unit; and the control unit controls whether the switch unit is conducted or not according to the voltage value of the energy accumulating unit, and further controls the energy accumulating unit to accumulate the direct current electric energy.

Description

technical field [0001] The present invention relates to a power storage system, in particular to a solar power storage system. Background technique [0002] Due to global climate change, air pollution problems and resource shortages, people have gradually developed the use of solar power as the main source of power supply. Sunlight is a renewable, inexhaustible, and inexhaustible natural energy source. It uses solar panels to directly convert the energy of light into electrical energy. During the power generation process, no polluting gases such as carbon dioxide will be produced. Due to the characteristics of safety and convenience, the solar panel market, which is dominated by silicon wafers, is growing rapidly in recent years. [0003] Even though there are many advantages of using solar power to generate electricity, solar energy is greatly affected by climate and day and night, so its stability is poor. It is necessary to use additional energy storage devices, such as ...

Problems solved by technology

[0003] Even though there are many advantages of using solar power to generate electricity, solar energy is greatly affected by climate and day and night, so its stability is poor. It is necessary to use additional energy storage devices, such as batteries, pumped storage power plants, etc., to store the electrical energy converted from solar energy. Release the stored energy when there is no sunlight or at night

However, the batteries currently used, although advertised as reusable, still have a limited lifespan.

In the case of repeated charging and discharging or long-term non-use, the capacity of the battery will decrease and it will be easily damaged. The reason is that the battery uses chemical energy to convert into electrical energy. When all the activity of the compound is used up or will be used up, new chemical reactions can no longer be carried out, which will lead to the aging of the battery and the end of its life

[0004] Moreover, although solar energy can cost-effectively generate a large amount of electric energy, ordinary batteries cannot provide the same amount of capacity to store electric energy, so the number of charge and discharge must be increased, which in turn reduces the service life of the battery

If multiple batteries are used to store electrical energy, the structure of the charging circuit is complicated, the space is too large, and the cost is expensive.
