Abstract: Now-a-days numerous of Electrical consumption devices are developed for the sophistication of Human Life. Hence, Non-Renewable Sources are reducing and not possible to meet future Electrical Demand alone with it. That?s why making use of Renewable Resources especially Solar and Wind are potential in the universe. So, for sustainable generation of Electricity to meet the demand of future endeavours, Renewable Energy plays a significant role. In this paper, [6] it is motivated to track the Solar Energy with the help of Sun Tracking Solar System (STSS). It is a device [5] that operates to track and rotate by adjusting the angle of the solar panel to orient itself, towards the normal of solar rays all the time during the day. STSS mainly consists of Sensors, Electronic Devices like Resistors, Inductors, Capacitors, Microprocessor and Motor. If STSS fails, tracking Solar Energy is Difficult and subsequently generation of Electricity reduces since Solar Panel will not move along the Sun Rays. Hence, it is more essential to understand Reliability Prediction [1] of STSS. Generally, failures of STSS may be due to sophisticated components like Electronic Devices rather than robust equipment like Motor. In this paper, it is proposed to Perform Reliability Prediction of Sun Tracking Solar System in terms of Mean Time Between Failures (MTBF) by using the Bellcore standard [7] and its validation through High Accelerated Life Testing (HALT) results.
