Problems solved by technology

[0006] The present invention provides a solar cell system capable of automatic dust removal to solve the problem that the existing dust removal system wipes back and forth on the surface of the solar photovoltaic panel by the dust removal brush, which easily causes dust to accumulate on the surface of the solar photovoltaic panel, resulting in the dust being only removed from the surface by the dust removal brush. Brushing from one side to the other, and then turning back along the original path, cannot effectively clean the dust on the surface of the solar cell

Embodiment 1

[0030] like figure 1 and 2 As shown, the solar battery system of this embodiment includes a solar photovoltaic panel 1 , a dust removal brush 2 , two conveyor belts, four supporting wheels and a driving motor 5 .

[0031] like figure 1 As shown, a driving motor 5 is fixed on the top edge of the solar photovoltaic panel 1, and four supporting wheels are symmetrically distributed on the outside of the four corners of the solar photovoltaic panel 1, wherein the supporting wheel 41 is coaxial with the supporting wheel 44, and the supporting wheel 42 is coaxial with the supporting wheel 43 coaxial.

[0032] The supporting wheel 41 is connected with the driving motor 5; two guide blocks are arranged on the lower edge of the solar photovoltaic panel 1, and coaxial through holes are arranged on the two guide blocks, and a rotating rod 6 passes through the through holes on the two guide blocks , is connected to the solar photovoltaic panel 1 in rotation, the support wheel 42 and the...

Embodiment 2

[0047] like image 3 and 4 As shown, the solar battery system of this embodiment includes a solar photovoltaic panel 11, a dust removal brush 21, two conveyor belts, four supporting wheels and a driving motor. Wherein except that the dust removal brush 21 and the solar photovoltaic panel 11 are different from the first embodiment, other structures are the same as the first embodiment.

[0048] The solar photovoltaic panel 11 has a smooth surface, and the dust removal brush 21 is a strip-shaped scraper. The friction force between the panels 11, and the slope generated by the chamfering is attached to the front of the solar panel 11.

[0049] During work, the surface of the dust removal brush 21 is seamlessly attached to the front of the solar battery panel 11, and the dust removal effect is better.

[0050] To sum up, in Embodiment 1 and Embodiment 2, the movement trajectories of the dust removal brush 2 and the dust removal brush 21 are circular, and the accumulated dust ca...

Abstract

The invention discloses a solar cell system capable of automatically removing dust. The solar cell system comprises a solar photovoltaic panel and a dust removal brush with a driving mechanism, the dust removal brush is provided with an annular motion path, at least one section of the motion path is a working section, and the dust removal brush fits with the front of the solar photovoltaic panel when moving along the working section. By changing the motion track of a dust removal brush in a dust removal structure of an existing solar photovoltaic panel, accumulated dust is taken away from the solar photovoltaic panel, and dust removal effects are improved. The motion track of the dust removal brush is annular, the driving mechanism only needs to unidirectionally run, a mechanical structure is simplified, and stability and reliability of a system are enhanced.

Description

technical field [0001] The invention relates to a solar battery system, in particular to a solar battery system capable of automatic dust removal. Background technique [0002] With the advent of the worldwide energy crisis, governments of various countries are actively promoting green energy for the purpose of sustainable economic development. In recent years, solar energy has gradually been valued by countries all over the world because of its remarkable characteristics such as non-pollution, renewable, and wide range, and it will become one of the most potential green energy sources in the next few decades. [0003] However, the highest photoelectric conversion efficiency of solar cells is only about 14%-16%, which has become the biggest obstacle hindering the progress of solar power generation technology. Therefore, it is very important for the entire photovoltaic system to make full use of this limited solar energy resource. However, in order to fully absorb solar ene...
