Referring to fig. 4, in case of rain, when the raindrop sensing sensor measures that the diameter of the raindrop is less than or equal to 0.5mm, the processor controls the angle adjusting module to face the photovoltaic panel 1 back to the wind and rain direction; when the diameter of the raindrops measured by the raindrop sensor is larger than 0.5mm, the processor controls the angle adjusting module to enable the photovoltaic panel 1 to face the wind and rain direction. By adopting the method, when the rainwater is too small, the cleaning effect cannot be achieved, and rain marks are easily left on the photovoltaic panel 1, the processor controls the angle adjusting module to enable the photovoltaic panel 1 to face the wind and rain direction back, so that the photovoltaic panel 1 cannot be drenched by the rainwater, and the rainwater can be prevented from being left on the photovoltaic panel 1 when the rainwater is too small.
Specifically, the photovoltaic panel 1 faces the wind and rain direction, that is, the front surface of the photovoltaic panel 1 faces the wind and rain, and the rainwater strikes the front surface of the photovoltaic panel 1. Photovoltaic board 1 is back to the wind and rain direction, and the back of photovoltaic board 1 faces the wind and rain, and the rainwater hits and hits on the back of photovoltaic board 1.
Referring to fig. 4, when the raindrop sensor measures that the diameter of the raindrop is larger than 0.5mm, the raindrop sensor sends raindrop information to the processor, and after the processor controls the angle adjusting module to back the photovoltaic panel 1 to the wind and rain direction for 5 minutes, the processor controls the angle adjusting module to enable the photovoltaic panel 1 to face the wind and rain direction. The purpose of adopting the steps is that at the beginning of 5 minutes, due to a large amount of dust in rain, the photovoltaic panel 1 is firstly back to the wind and rain direction for 5 minutes, so that the dust in the rain is prevented from being brought into the photovoltaic panel 1; when the rainwater does not contain dust, the cleaning effect can be improved.
Referring to fig. 1 to 3, the present embodiment further discloses a photovoltaic device, which includes a photovoltaic panel 1 and a cleaning system disposed on the photovoltaic panel 1.
The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
