Solar cell module efficacy monitoring system and monitoring method therefor

摘要

A solar cell module efficacy monitoring system includes a reference module which includes a solar power generation module and is to be maintained in a clean condition, an evaluation module which includes a solar power generation module and is to be covered by dust in an environment, maximum power point tracking devices which track powers of the reference module and the evaluation module and maintain power outputs at maximum points by connected to the reference module and the evaluation module, respectively, and, a PV communication recording device which records power generation results of the reference module and the evaluation module by connected to the reference module and the evaluation module, and a calculation display device which calculates power loss due to accumulation of dust on the evaluation module by connected to the PV communication recording device.
