Design & Simulation of Sun Tracking System Using Plc

Non renewable energy is a relatively short-term energy source; consequently, the uses of alternative sources such as solar energy are becoming more wide spread. To make solar energy more viable, the efficiency of solar array systems must be maximized. A feasible approach to maximizing the efficiency of solar array systems is sun tracking. PV modules are devices that cleanly convert sunlight into electricity and offer a practical solution to the problem of power generation in remote areas. The Sun Tracking system using PLC designed offers a reliable and affordable method of aligning a PV module with the sun in order to maximize its energy output. Design of Sun Tracking system using PLC is a hybrid hardware/software prototype, and consists of SCADA system which automatically provides best alignment of PV panel with the sun, to get maximum output (electricity) with monitoring the system by controlling the movement with Programmable Logic Controller (PLC) and minimizing the loss of energy that is applied for the control system. By applying the proposed technique it is expected that the efficiency of the PV plant will maximize.
