The invention discloses a micro-grid operation and maintenance management method and system, and the method comprises the steps: firstly judging whether a photovoltaic panel is shielded by sundries through image analysis, so as to judge whether the power generation amount is reduced by the sundries; if the power is not shielded by sundries and the output power is suddenly reduced, it can be determined that the power generation amount is reduced due to the line fault of the photovoltaic power generation system, and if the output power is not suddenly reduced, it is indicated that the real-time output power is slowly reduced, that is, the output power is gradually reduced under the effect of dust accumulation; if yes, it can be determined that the power generation amount is reduced due to too much dust on the photovoltaic panel; according to the method provided by the invention, the specific reason causing the reduction of the generating capacity of the photovoltaic panel can be accurately analyzed, so that tar
