Abstract

The invention provides a photovoltaic system which comprises a support, a photovoltaic module fixed on the support, a temperature sensor for detecting the temperature of the photovoltaic module and the environmental temperature, a data comparison device comparing the temperature of the photovoltaic module with the environmental temperature, a main control device connected with the temperature sensor and the data comparison device and a parameter setting device which is connected with the main control device and contains a first preset temperature difference value. The support is provided with a cleaning device for spraying cleaning fluid on the surface of the photovoltaic module. When a temperature difference value obtained after the data comparison device compares the temperature of the photovoltaic module with the environmental temperature is larger than the first preset temperature difference value, the main control device starts the cleaning device.

Description

technical field [0001] The invention relates to a photovoltaic system, in particular to a photovoltaic system with a cleaning function. Background technique [0002] Solar energy is the cleanest, safest and most reliable energy source in the future. Countries around the world are taking the development and utilization of solar energy as the main content of the energy revolution for long-term planning and are actively developing photovoltaic modules. However, when the photovoltaic module is working outdoors, a large amount of dust will adhere to the surface. Due to the blocking of dust, the photovoltaic module receives less energy from the sun, resulting in lower power generation of the photovoltaic module. In the present technology, it can only be cleaned with a mop regularly by manpower. However, this kind of cleaning method has the characteristics of high labor intensity and difficult wiping. [0003] Therefore, it is necessary to provide an improved photovoltaic system...
