Embodiment Construction

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present invention, not to limit the present invention.

[0021]The present invention provides a photovoltaic module dust accumulation monitoring and cleaning reminding system and method. The environment of the photovoltaic modules in the photovoltaic power generation system is exactly the same, and the parameters such as power generation capacity, module model and installation inclination angle are exactly the same. In addition, the dust accumulation simulation system consists of two simulation units, namely the first simulation unit and the second simulation unit; the first simulation unit includes the first simulated photovoltaic ...

Abstract

The invention provides a photovoltaic module accumulated dust monitoring and cleaning reminding system and method. The photovoltaic module accumulated dust monitoring and cleaning reminding system includes an accumulated dust simulation system, a cleaning reminding unit and a central control system, wherein the accumulated dust simulation system is arranged in an actually running photovoltaic power generation system whose degree of accumulated dust needs to be monitored, and includes a supporting mechanism, a first analog unit and a second analog unit. The working principle of the system is that modules in the first and second analog units are adopted to simulate actual running photovoltaic power generation system modules before and after cleaning respectively, and accumulated electric quantity difference between the two is traced in real time till single-time cleaning cost is reached and cleaning reminding information is sent out; and at initial moments of different cleaning cycles, the modules in the first and second analog units need to be alternately cleaned so as to ensure that the accumulated dust situation of the actual running photovoltaic power generation system can be represented. The system and method have the advantage that optical cleaning time of the modules in the actual running photovoltaic system can be determined easily and accurately, thereby truly realizingoperation revenue maximization.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a photovoltaic module dust accumulation monitoring and cleaning reminder system and method. Background technique [0002] The dust accumulation on the surface of photovoltaic modules in photovoltaic power plants will not only reduce the solar radiation transmittance, hinder the heat dissipation of photovoltaic modules, but also easily corrode the surface of photovoltaic modules, thus affecting the output performance and life of photovoltaic modules. Relevant data show that the power loss caused by dust accumulation on the surface of photovoltaic modules can reach 2-10% in one month, and even greater in some cases. Therefore, timely cleaning of photovoltaic modules is of great significance for improving power generation capacity and equipment reliability of power stations. [0003] Since the dust accumulation of photovoltaic modules in different ...
