Apparatus able to track sunlight by three angles for photovoltaic (PV) power generation includes: a solar cell module; a solar cell holder; an angle-adjustable platform; a driving motor; a holding pillar and a tracking sensor. The apparatus for PV power generation can generate electric power at three specific angles in a day. The tracking sensor can track the position change of the sun by utilizing the driving mechanism to switch among different positioning statuses. Through the optimized design and the cooperation of the tracking sensor and the positioning mechanism, the apparatus for PV power generation of the present invention can achieve a highest efficiency elevation of the electric power generation by minimum tracking motions.
