JUNCTION BOX WITH MPPT CONTROL FUNCTION IN SOLAR CELL MODULE AND DRIVING METHOD FOR THEREOF

摘要

PURPOSE: A junction box including an MPPT control function in a solar cell module and a driving method thereof are provided to improve power generation efficiency by controlling the output of an output terminal. CONSTITUTION: A voltage and current sensor senses the current and the voltage of a solar cell module. A temperature sensor senses the temperature of the solar cell module. An MPPT control unit(120) tracks the maximum power point of the voltage and the current. A voltage control unit(130) includes a switch to control the operation of the solar cell module. A wireless transmitting unit(140) wirelessly transmits the sensing value of the temperature sensor to a control server.
