The present invention relates to a switching system of a panel array. More specifically, the present invention relates to a switching system of a panel array, in which a array background of each photovoltaic panel belonging to the array is integrally managed by a controller based on an amount of generated power or a characteristic of each panel, thereby prevented the performance of specific panels in the array from being degraded as the insulation of a cell constituting to the photovoltaic panel is deteriorated according to the time elapse due to high voltage applied to the panel positioned at an end portion of the array. According to the present invention, the power generation state of each photovoltaic panel can be accumulated for the monitoring of the power generation at a remote place, and a replacement time point of the photovoltaic panel to generate power at a high potential is calculated, so that the electrical array of the photovoltaic panel reaching at the replacement time point can be remotely changed. Accordingly, the electrical array of the photovoltaic panel to be lowered in durability is varied in the array while using the panel array structure having a deteriorated insulating characteristic. Accordingly, power is generated at lower potential through remote control, thereby reducing the damage of the photovoltaic panel and increasing the reliability, so that the stability and the lifespan of the system can be increased. |
