Background technique

Solar power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. Photovoltaic effect, referred to as "photovoltaic effect", refers to the phenomenon that light causes a potential difference between different parts of an inhomogeneous semiconductor or a combination of semiconductor and metal. It is firstly the process of converting photons (light waves) into electrons and light energy into electrical energy; secondly, it is the process of forming voltage. With voltage, it is like building a high dam. If the two are connected, a current loop will be formed. The advantage of photovoltaic power generation is that it is less restricted by region, because the sun shines on the earth, and the photovoltaic system also has the advantages of no noise, low pollution, no need to consume fuel and erect transmission lines, and it can generate electricity and supply power on site, and the construction period is short.

It is a common technology to use the solar power generation system to charge the battery with energy storage. After the traditional solar energy is converted from light energy to electric energy, the battery is charged through the solar controller, or the electric energy is supplied to the AC load after passing through the solar controller and inverter. , or the solar panel directly supplies power to the DC load. At present, the solar energy used on the market charges the battery. After the battery is fully charged, as long as the user does not cut off the input power of the charger, the charger will continue to charge the battery, which will shorten the life of the charger. The service life of the charger increases the failure rate of the charger, which is likely to cause other unsafe accidents. When stopping solar energy to charge the battery, the connection between the charging controller and the solar panel should be disconnected first, and then the connection between the charging controller and the battery should be disconnected. Otherwise, it is easy to cause charger failure. Also there is the shortcoming of wasting electric energy in the prior art.

At the same time, once the voltage of the solar panel is lower than the voltage of the battery, the charging process will stop until the power of the solar panel is restored. In daily life, due to the constant change of light, the charging of the battery is also extremely unstable. If the charging is too frequent, it is easy to reduce the life of the battery and greatly reduce the charging efficiency. Due to the above shortcomings, solar-charged storage batteries cannot be widely used in various fields, which limits the progress of science and technology.

Sun position tracking has proven to be the primary means of increasing solar energy efficiency. The so-called sun position tracking refers to adjusting the position angle of the solar receiving panel so that its light-receiving surface is always perpendicular to the sun's rays. Similar to the principle of sunflowers, the purpose is to allow the effective light-receiving surface to collect more solar energy. For the same solar receiving panel, when it is perpendicular to the direction of solar radiation, the received solar energy is roughly three times that of the solar radiation energy received when it is fixed facing south.

In the current solar energy for photovoltaic power generation, solar water heating and other systems, the installation direction of solar panels is generally fixed according to the local sunshine conditions, so most of the time the sun's rays and the light-facing surface of the solar panels are not completely Vertically, the utilization and conversion rate of solar energy is low. In order to improve the absorption and conversion efficiency of solar panels, some methods and technologies are used to adjust the solar panels so that the sun's rays strike the solar panels as vertically as possible. Most of the traditional methods are to record the local solar trajectory, and then automatically adjust the solar panels according to the recorded information according to the solar trajectory. For example, the active solar tracking method and device announced in Chinese Patent No. 200910100808.6 and the toothed belt transmission group synchronously tracking solar automatic tracking device based on the orbit of the earth and the sun announced in 200910086319. Tracking, the problems of this type of method are: first, the sun’s irradiation angles are different in different places, so different regions must record different sun trajectory information and operate according to different information, and the workload is heavy; It is more complicated; the third is that the sun's rays do not have obvious directivity in cloudy and rainy days, but the motor system still consumes power to work.
