Solar cell module efficacy monitoring system and monitoring method therefor

A method for solar cell module efficacy monitoring, the method comprising:

• providing a reference module comprising a solar power generation module and configured to be maintained in a clean condition;
• providing an evaluation module comprising a second solar power generation module;
• recording power generation results of the reference module and the evaluation module;
• and
• comparing the power generation results of the reference module and the evaluation module to determine power loss due to accumulation of dust on the evaluation module.

A solar cell module efficacy monitoring system, comprising:

• a reference module comprising a solar power generation module and configured to be maintained in a clean condition;
• a cleaning device connected to the reference module and configured to clean the reference module;
• an evaluation module comprising a second solar power generation module;
• a PV communication recording device, connected to the reference module and the evaluation module, that records power generation results of the reference module and the evaluation module;
• and
• a calculation display device, connected to the PV communication recording device, configured to calculate power loss due to accumulation of dust on the evaluation module.
