Abstract

The invention discloses a cooling control method, device and system for a photovoltaic module, and the method comprises the steps: obtaining a first actual backboard temperature and actual solar irradiation intensity of the photovoltaic module when the photovoltaic module in a cooling control region is in an operation state; whether the first actual backboard temperature and the actual solar irradiation intensity meet preset conditions or not is judged; and if yes, controlling the cooling device to perform cooling operation on the photovoltaic module. By automatically executing an intelligent algorithm, under the condition that the water consumption is reduced as much as possible, the temperature of the photovoltaic module is reduced, the power generation efficiency is improved, and the power generation income is increased; through the cooling system, intelligent water spraying operation on the surface of the photovoltaic module is realized, so that the temperature of the photovoltaic module is effectively reduced; the water spraying operation can also promote the surface of the photovoltaic module to keep clean, and the cleaning cost is reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a cooling control method, device and cooling system for photovoltaic components. Background technique [0002] Solar photovoltaic modules can convert solar energy into electrical energy and at the same time attract a lot of heat, which increases the temperature of photovoltaic modules and reduces the photoelectric conversion efficiency of photovoltaic modules. Changes in temperature will significantly change the output performance of photovoltaic modules, resulting in a large power loss, and if the photovoltaic modules are kept at a high temperature for a long time, the life of the photovoltaic modules will be seriously attenuated. [0003] The existing cooling method can be to lay cooling water pipes on the back of the photovoltaic modules, and the cooling fluid flowing in the cooling water pipes will take away the heat in the photovoltaic modules, so as to...
