A study on the improvement of solar pv panel efficiency and power output

Solar Tracking System is a unit used in many solar energy systems such as for concentrating a solar lens or reflector or orienting a solar panel in the direction of sun. In photovoltaic (PV) systems, trackers enable to reduce the angle of incidence between the incident sun light and the PV panel, which improve the energy generation of the PV panel. In this thesis, we proposed a dual axis tracking system for a PV panel and investigated several factors that should be put in consideration involves: the level of direct solar irradiation, feed-in tariffs in the location in which the system is set up, and also the cost to maintain and install the trackers. The goal of this thesis is to design two axis trackers in PV panel is to place the solar panels perpendicular towards the sun's rays. For tracking system, a spherical solar cell indicator has been used in order to analyzing electrical energy generation for almost all direction in real time to determine the best position that panel should be directed. It consisted of several solar cell arranged on semi spherical structure. The energy product from each cell will be amylases by specific program in microcontroller that will determine best direction that PV panel should be aligned and control the solar trackers in order to rotate on horizontal and a vertical axis. The result shows the the prposed system got a good acuricy and the reltivaly improvement in power generation.
