Abstract

The invention discloses a control method of a photovoltaic module cooling system and the photovoltaic module cooling system. The photovoltaic module cooling system comprises a temperature detection device and a spraying device. The control method comprises the steps of under the condition that the temperature detection device detects that the temperature of a photovoltaic panel of a photovoltaic module is higher than a first preset temperature, controlling the spraying device to spray water to the photovoltaic module; when the spraying time reaches a first preset time, controlling the sprayingdevice to stop; and after the spraying device stops, controlling the spraying device through a preset control strategy so as to enable the temperature of the photovoltaic panel of the photovoltaic module to be within a preset temperature range corresponding to the current irradiance. The problem of poor cooling effect of the photovoltaic module in the prior art is solved, and the power generationefficiency of the photovoltaic module is improved. In addition, rapid heating and rapid cooling of the photovoltaic module in a short time are avoided, and the service life of the photovoltaic moduleis prolonged.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a control method of a photovoltaic module cooling system and a photovoltaic module cooling system. Background technique [0002] Since the power generation efficiency of the photovoltaic power generation system is very sensitive to the temperature of the photovoltaic module, when the temperature of the photovoltaic module rises, the output power of the photovoltaic module will decrease significantly. For example, if the temperature of the photovoltaic module increases by 1°C, the conversion efficiency will decrease by 0.4~ 0.5%. Therefore, it is necessary to cool down the photovoltaic module and keep the temperature of the photovoltaic module at a low level to improve the conversion efficiency and output power of the photovoltaic module. [0003] At present, the cooling methods of photovoltaic modules mainly include active cooling and passive cooling. Amon...
