Dedusting and cooling integrated device of solar photovoltaic panel

Abstract

The invention discloses a dedusting and cooling integrated device of a solar photovoltaic panel. The dedusting and cooling integrated device of the solar photovoltaic panel comprises a dedusting system, a cooling pipeline system, a water pool and the solar photovoltaic panel installed on the water pool, wherein the dedusting system comprises a showering pipe installed at the top end of the solar photovoltaic panel, the showering pipe is communicated with the water pool through a water pump, the solar photovoltaic panel is provided with a hair brush used for cleaning the solar photovoltaic panel, and the bottom end of the solar photovoltaic panel is communicated with the water pool through pipelines; the cooling pipeline system comprises a cooling plate provided with a cooling pipeline, and the outlet and the inlet of the cooling plate are communicated with a horizontal spiral pipe which is placed in the water pool. According to the dedusting and cooling integrated device of the solar photovoltaic panel, manpower cost and used water of washing are greatly saved, dedusting operation can be carried out timely, and power generating efficiency of the solar photovoltaic panel can be effectively improved. Compared with an independent dedusting device and a cooling device, the dedusting and cooling integrated device of the solar photovoltaic panel achieves dedusting and cooling integration, comprehensive energy consumption of the device is low, and investment of equipment is low while same production capacity is achieved.

Description

technical field [0001] The invention belongs to the field of solar photovoltaic power generation, and in particular relates to a dust removal and cooling integrated device for solar photovoltaic panels. Background technique [0002] The daylighting glass of solar photovoltaic panels has been exposed to sunlight and rain outdoors for a long time and is polluted by the external environment. The dust pollution layer formed on the surface will affect the light penetration rate, thereby greatly reducing the conversion efficiency of photovoltaic cells. However, photovoltaic power stations are often built in barren and inhabited places, which results in high manual cleaning costs. [0003] The peak power of solar cells decreases with the increase of temperature, that is, the peak power loss rate of solar cells is about 0.35-0.45% for every 1 °C increase in temperature. Therefore, the cooling of solar photovoltaic panels is of great significance to the efficiency of solar cells. ...
