Abstract
The invention provides a photovoltaic module dust detecting method and system. The method comprises the steps: employing a double-side photovoltaic module as a test module; extracting and outputting afront surface electrical parameter and a back surface electrical parameter of the test module through an electrical parameter extraction device via the characteristic that the dust is liable to be accumulated on the front surface of the double-side photovoltaic module but not the back surface after a detecting device transmits a testing instruction; obtaining a front surface no-dust electrical parameter corresponding to the back surface electrical parameter according to a preset relation table through the detecting device, and comparing the front surface electrical parameter and the front surface no-dust electrical parameter, and generating and outputting a module cleaning instruction when the relation between the front surface electrical parameter and the front surface no-dust electricalparameter meets a cleaning condition. In the invention, there is no need of an additional protection cover or cleaning device for achieving the detecting of the accumulated dust of the photovoltaic module. Compared with the prior art, the method reduces the detection cost of a system.
Description
technical field [0001] The invention relates to the technical field of photovoltaic module dust detection, in particular to a method and system for detecting photovoltaic module dust. Background technique [0002] In order to evaluate the impact of dust on the power generation of photovoltaic modules, the reference module method is usually used at present, that is, the electrical parameters of the module to be evaluated are compared with the cleaned reference module, and the degree of dust accumulation is determined by the difference between the two. [0003] In the prior art, the reference components are usually protected with a dust cover, and when testing is required, the dust cover is opened for a comparative test, and after the test, the dust cover is used to protect it again; or, two sets of additionally equipped small components are used as dust In the detection system, one group is automatically cleaned regularly through the cleaning device, and the other group is in...
