Photovoltaic module

A photovoltaic module comprising:

• a solar cell module including a plurality of solar cells;
• a junction box including a plurality of bypass diodes and a dc/dc converter unit to convert a level of DC power supplied from the solar cell module;
• a plate on one surface of the solar cell module between the solar cell module and the junction box;
• and
• a coupling member attaching and detaching the junction box from the solar cell module,
• wherein the solar cell module further includes a plurality of solar cell strings formed with some of the plurality of solar cells connected in a row, and a plurality of conductive lines electrically connecting the plurality of solar cell strings and the plurality of bypass diodes within the junction box,
• wherein the plurality of conductive lines are extended to a rear surface of the solar cell module through corresponding openings formed in the solar cell module.
