A Study on the Output Characteristics of Photovoltaic Tracking System for one and two Direction

Photovoltaic system is easier to operate and maintain than the other power generating system since it generally contains no moving parts, operate silently and require very little maintenance. In order to increase the efficiency of Photovoltaic system, it is generally used three methods just like increasing the efficiency of solar cell, energy conversion system included maximum power point(MPPT) control algorithm and using sun tracking system. Photovoltaic power systems convert sunlight directly into electricity. A residential PV power system enables a homeowner to generate some or all of their daily electrical energy demand on their own roof, exchanging daytime excess power for future energy needs. Nowaday, the efficiency of solar cell is maximum 24[%], but it pulls up a unit coast in electrical generation system to increase the efficiency of a cell. In this paper, it is proposed solar tracking system, the system designed as the normal line of the solar cell always runs parallel the ray of the sun. The fixing and tracking photovoltaic system were compared with experimental method.
