Problems solved by technology

[0004] The purpose of the present invention is to: address the above-mentioned problems, provide a self-cleaning solar panel, adjust the angle at which the solar panel receives solar energy, so that the solar panel can receive solar energy more effectively, and realize efficient utilization of solar energy. In addition, through The different effects of a variety of different solar cells can realize the effective use of solar energy with different light intensities, thereby improving the utilization rate and conversion rate of solar energy, and bringing convenience to life. Another convenience, the temperature controller of this structure can Control and adjust the temperature of the solar panel, so as to realize the temperature conversion of the solar cell in the most suitable range, and further improve the conversion rate. This device can also clean the solar wafer to avoid the decrease of the conversion rate caused by the low transparency. , and the cleaning work will not affect the conversion of solar energy, the two are independent of each other, in addition, at night, the solar chip can be rotated to the inside of the fixed frame, so that the ceramic plate faces outward, which can effectively protect the solar chip and improve the use of the solar chip life

Abstract

The invention relates to a self-cleaning solar panel. The self-cleaning solar panel comprises a fixed frame, a photovoltaic module, an incident light detector, a turning mechanism, a controller and a cleaning apparatus. The self-cleaning solar panel also can clean solar wafers to avoid the decline of conversion efficiency caused by not high enough transparency; the cleaning operation does not influence the solar energy conversion, and the cleaning operation and the solar energy conversion are performed independently; in addition, the solar wafers can be turned to the internal of the fixed frame to enable a ceramic plate to face to the outside at night, so as to effectively protect the solar wafers and prolong the service life of the solar wafers; the cleaning apparatus can ensure the simultaneous implementation of the solar wafer cleaning and the solar energy conversion by the solar wafers without causing interference between each other; meanwhile, the influence on the solar wafers is avoided in the simultaneous implementation of the solar wafer cleaning and the solar energy conversion by the solar wafers; and in addition, the damage of the solar wafers caused by overhigh partial temperature difference among the solar wafers in the cleaning process can be prevented, and the voltage supply quality and the service life of the solar wafers can be ensured.

Description

technical field [0001] The present invention relates to a self-cleaning solar panel. Background technique [0002] A solar panel module is a power generation device that collects heat when exposed to sunlight and converts light energy into direct current electricity. It is composed of thin solid photovoltaic cells almost entirely made of semiconductor materials (such as silicon). Since there are no moving parts, it can be operated for a long time without any wear and tear. Simple photovoltaic cells power watches and computers, and more complex photovoltaic systems light homes and power the grid. Solar panel components can be made into different shapes, and the components can be connected to generate more electricity. Solar panel components are used on roofs and building surfaces, and are even used as part of windows, skylights or shading devices. These photovoltaic facilities are usually called building-attached photovoltaic systems. [0003] Compared with a solar photovo...
