Tracking-type window blind apparatus using solar modules

A tracking-type blind apparatus using solar modules, comprising:

• a plurality of sunshades which are separated from each other by a controlled distance and adjust a light transmission amount;
• solar modules which are respectively attached to partial area of each of the plurality of sunshades and generating power by using solar light;
• a driver which is connected with the plurality of sunshades to adjust an inclination angle of each sunshade and a distance between the sunshades;
• and
• a controller which sets one of operation modes among a power generation mode, a privacy protection mode, and a lighting mode according to a user's command, and controls the inclination of each sunshade and the distance between the sunshades according to the set operation mode, a current season and time, and a solar altitude angle,
• wherein each of the plurality of sunshades further comprises a rotation axis that divides each of the plurality of sunshades into a first region to which the solar module is attached and a second region to which the solar module is not attached, and
• wherein at least one of the first region and the second region rotates with reference to the rotation axis by controlling of the controller such that an angle between the first region and the second region is changed.
