Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to a solar photovoltaic power generation device. Background Art

[0002] The core of solar photovoltaic power generation is photovoltaic cells, which are composed of two layers of semiconductor materials. When sunlight shines on photovoltaic cells, photons are absorbed and release electrons and holes, forming current under the action of the electric field, thereby converting light energy into electrical energy, which can reduce the demand for traditional energy and reduce energy consumption. At present, in order to improve power generation efficiency, several photosensitive sensors are used to detect the intensity of sunlight in different directions in real time. The photosensitive sensor in which direction has the highest light intensity is driven by the motor to rotate and automatically adjust the angle of the photovoltaic panel according to the current position angle of the photovoltaic panel itself, so that it can better receive light, thereby maximizing the absorption of solar energy and improving power generation efficiency. The photosensitive sensor needs to be protected by a transparent protective cover during use.

[0003] The transparent protective cover is exposed to the air for a long time, and impurities are easily attached to the surface, especially on both sides of the road, which will increase the amount of dust adhesion. The dust will reduce the light transmittance of the transparent protective cover, affect the detection accuracy of the photosensitive sensor and the adjustment angle of the photovoltaic panel, and reduce the power generation efficiency. In the prior art, the photosensitive sensor and the transparent protective cover are arranged at the top of the photovoltaic bracket with a height of one end. It does not have a self-cleaning function and needs to be manually cleaned on the surface of the transparent protective cover at regular intervals. Due to the large number of photovoltaic power generation devices, the labor intensity of the manual labor will be greatly increased, which is time-consuming and labor-intensive. In addition, manual cleaning may not be in place, which will affect the light transmittance of the transparent protective cover and the detection effect of the photosensitive sensor, and reduce the efficiency of solar photovoltaic power generation. Summary of the invention

[0004] The present invention provides a solar photovoltaic power generation device, which is capable of cleaning a transparent protective cover, can reduce cleaning dead angles, improve the cleaning effect, greatly reduce the labor intensity of manual labor, save time and effort, is convenient and fast, can ensure the detection accuracy of the photosensitive sensor, and improve the beneficial effect of the power generation rate of the photovoltaic power generation panel, and solves the problem mentioned in the above background technology that the surface of the transparent protective cover needs to be manually cleaned at regular intervals.
