Problems solved by technology

However, at present, photovoltaic dust monitoring is mainly through human subjective observation, but human subjective observation cannot well judge the impact of dust on the photovoltaic power generation system, so cleaning it when the dust has little impact will waste manpower, material resources and Financial resources, but if the dust has been greatly affected and it is not cleaned, it will reduce the power generation efficiency and damage the life of the photovoltaic unit

Abstract

A photovoltaic plate dust detecting device comprises a dust sensor, an irradiance sensor, a power measuring unit and a controller. The dust sensor is connected to the controller. The irradiance sensor is connected to the controller. The power measuring unit is connected to the controller. The controller is connected to the dust sensor, the irradiance sensor and the power measuring unit and is used for outputting a control signal according to the received dust quantity value, the received irradiance strength value and / or the received generating power value. According to the photovoltaic plate dust detecting device, the effect of dust on the photovoltaic generating efficiency can be shown through quantitative data, and therefore a photovoltaic plate can be cleaned in a targeted mode, waste of manpower and material resources due to frequent cleaning and the effect on the generating benefit due to decreasing of the generating efficiency caused by irregular cleaning are prevented, and the photovoltaic plate dust detecting device plays an important role in reducing the running cost of a photovoltaic power generation system and improving the generating efficiency of the photovoltaic power generation system.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation control, in particular to a photovoltaic panel dust detection device. Background technique [0002] As society's demand for energy is increasing, the problem of "energy security crisis" is becoming more and more prominent, and the problem of "global warming" caused by traditional forms of energy utilization is also becoming more and more prominent. As a new form of energy, renewable clean energy is getting more and more attention, and solar energy can be used as an inexhaustible clean energy, so how to use solar energy reasonably and efficiently is before us A major subject. [0003] On-site measurement was carried out through photovoltaic power generation, and the measured results showed that dust accumulation had a significant impact on photovoltaic power generation. The three effects of ash accumulation on photovoltaic panels: the shading effect of ash accumulation on ph...
