Using solar energy as a clean energy trends in replacement energy market. Solar heating system, photovoltaic, and lightshelves are frequently applied on the buildings. And Then, the various types of solar tracking systems also have been developed to improve the efficiency of solar energy. This study aims to introduce the principles of sun-location in the sky and
several solar tracking methods and to analyze various application examples. The existed sun-location principles of a Spencer, a Pitman, a Walraven, a Lamm and a Michalsky are introduced by literature. Also, the strong and week points of three types of solar tracking systems, a sensor, a program, and the program and sensor systems are investigated. And then, the applied
examples are analyzed.
