Abstract
As an important means of expanding renewable energy resources, the use of solar energy rapidly increase. To make solar energy more viable, the efficiency of solar array systems must be maximized. Photovoltaic generation has now-adays proved to be a cost-effective method for renewable environment impact. The sun tracking is feasible approach for maximizing the efficiency of solar array systems. The simulation for the Maximum Power Point Tracking (MPPT) system is developed and validated. The design and construction of a proto type for solar tracking system with two degrees of freedom, which detects the sunlight using photocells & having microcontroller based controlling is developed. This paper reports on the electrical output of solar panel be plotted on a graph of voltage vs. current curve. The resulting line on the graph shows the current output of the panel for each voltage at a specific light level and temperature. The design offers a reliable and affordable method of aligning a solar module with the sun in order to maximize its energy output.
