The present invention relates to a smart junction box for a solar cell module, and provides a smart junction box for a solar cell module which enables an operator to easily connect and separate ribbon cables using the operation of the levers of pressing units, thereby being able to improve the contact stability of ribbon cables, and which has a heat sink structure, thereby effectively emitting the heat generated by the ribbon cables and the diodes to the outside. For this purpose, the smart junction box for a solar cell module of the present invention includes bus bars for transmitting electricity flowing from ribbon cables; and pressing units for selectively fastening and separating the ribbon cables located on contact portions of the bus bars depending on whether both ends of the lever projected by the manipulation of an operator are inserted into recesses formed in a body.
