Water surface floating type photovoltaic module based on plateau area

Abstract

The invention discloses a water surface floating type photovoltaic module based on a plateau area, and relates to the technical field of solar power generation. The photovoltaic module comprises a solar panel, floating control assemblies and a floating support, wherein a supporting frame is arranged on the inner side surface of the floating support in an array mode; the solar panel is fixed in thesupporting frame; the floating control assemblies are uniformly arrayed on the peripheral side surface of the floating support; a cavity is formed in the floating support; the cavity is filled with liquid; the floating control assembly comprises a floating bottle; a light absorption material is placed in the floating bottle; and a circular pipe penetrates through the floating support and is inserted into the cavity. Under the action of the floating control assemblies and the floating support, the floating support is controlled to slowly sink, so that the heat dissipation effect of the solar panel located below the water surface is greatly improved, the deeper the heat production amount and water of the solar panel under sunlight are, the better the heat dissipation effect is, and the like, and the solar panel is controlled to be in the proper water depth according to the situation of the plateau area, so that advantage of the optimal temperature and sunlight intensity with the optimalpower generation efficiency is achieved.

Description

technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a floating photovoltaic module based on plateau areas. Background technique [0002] The air in the plateau area is thin and clean, with less dust and water vapor content, and the transparency of the atmosphere is higher than that in the plain area. The solar radiation transmittance increases with the altitude. Therefore, during photovoltaic power generation in plateau areas, it is very easy to have problems such as high temperature at noon, resulting in equipment damage and high temperature greatly reducing power generation efficiency. [0003] For photovoltaic modules in plateau areas, the main problem that needs to be solved is that the intensity of sunlight at noon is too strong, so that the temperature rises too high, resulting in a decrease in power generation efficiency.

Problems solved by technology

[0004] The purpose of the present invention is to provide a floating photovoltaic module based on the plateau area. Through the function of the floating control component and the floating bracket, when it is near noon, the light-absorbing material in the floating bottle will heat up relatively quickly, so as to control the floating The bracket sinks slowly, and the solar panels that have been waterproofed are sunk below the water surface. The heat dissipation effect of the solar panels below the water surface is greatly improved, and because sunlight has a certain loss rate on the water surface and in the water, that is The depth below the water surface will also reduce the intensity of sunlight absorbed by the solar panels, and the deeper the loss rate, the higher the loss rate, so the reduction in the intensity of sunlight will also reduce the heat production and water of the solar panels under sunlight. The deeper the heat, the better the heat dissipation effect, etc. According to the sunlight intensity and water temperature in the plateau area, it is controlled in a suitable water depth to achieve the advantages of a temperature and sunlight intensity with the best power generation efficiency; it also solves the problem of the noon sunlight intensity Too strong, so the temperature rises too high, leading to the problem of power generation efficiency decline
