The direction of sunlight is tracked according to variations of the altitude of the sun to maximize condensing efficiency. An apparatus for tracking and condensing sunlight includes a horizontal truss, a roof truss forming a triangular structure inclined to both sides of the horizontal truss, and a hinge formed on a top of the roof truss. Solar module plates are formed on both inclined surfaces of the roof truss to condense sunlight and interoperate with each other in a lateral direction. A driving means supports lower portions of the solar module plates, and moves the lower portions thereof so the solar module plates can pivot in both left and right directions around the hinge. The apparatus tracks sunlight and pivots the solar module plates to maximize condensing efficiency, improves energy production efficiency by using a roof area, and firmly fixes the solar module plate to the roof.
