Abstract
A photovoltaic module includes: a solar cell module including a plurality of solar cells; a junction box including a capacitor unit to store DC power supplied from the solar cell module, a dc/dc converter unit to level-convert the stored DC power and output the same; and a controller to control a voltage or current based on the supplied DC power from the solar cell module among a plurality of sections, calculate a local maximum power point in each of the sections using the controlled voltage or controlled current, determine a maximum power value among a plurality of calculated local maximum power points, and to control the dc/dc converter unit to output the level-converted DC power based on the determined maximum power value when a hot spot occurs in the solar cell module.
