Abstract: The present invention relates to an active control system for photovoltaic power generation module strings and an active control method therefor. More specifically, the present invention enhances the efficiency of a photovoltaic power generation since the system accurately determines whether each photovoltaic panel string and each photovoltaic module have a fault or not by determining the fault of each photovoltaic panel through the information of the voltage change and bypass of each photovoltaic module which is transmitted from junction boxes based on the pre-stored position information of the photovoltaic module of each arranged photovoltaic panel; increases the management convenience and efficiency of the photovoltaic power generation system because the system and the method rapidly prevent a power generation voltage value between strings which is caused by a partial shade situation by generating an optimal power transmission path from an automatic determination about the sequential shade situation which influences the total photovoltaic panels through the position information of the photovoltaic module of each arranged photovoltaic panel and accumulation information which manages each photovoltaic module; and optimizes the efficiency of the photovoltaic power generation because the system and the method individually check whether each photovoltaic panel has a fault or not and change the power transmission path which is formed between strings by gradationally determining whether each string and each photovoltaic panel have a fault or not through the voltage accumulation information of each string and the information of the voltage change and bypass accumulation of each photovoltaic module.
