Abstract: Disclosed is an apparatus for tracking and condensing sunlight of a wall installation type which tracks the position of the Sun and efficiently condenses sunlight according to variations of an altitude or orbit of the sun by installing a sunlight condensing device for adjusting an angle onto a wall. An apparatus for tracking and condensing sunlight of a wall installation type, comprises: a wall means 100; a sunlight condensing means 200 for condensing sunlight by forming onto a side surface of the wall means 100; and an opening and closing means 300 for adjusting condensing angle by opening or closing an end of the sunlight condensing means 200.

Abstract: There is provided an apparatus for tracking and condensing sunlight of a sliding type which tracks a direction of sunlight according to variations of an altitude or orbit of the sun pivots a solar module plate to maximize condensing efficiency, and strengthens a fixing structure on an inclined ground or inclined building surface by suing a frame structure on the bottom without using a concrete base harmful to natural environment.

Abstract: 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.
