Design and Fabrication of Solar Tracking System

Photovoltaic solar technology may be a multi-billion dollar clean, green and renewable energy industry, powering everything from road signs to entire cities. Solar cells themselves are essentially big PN-junction semiconductors, there’s plenty of advanced and rapidly evolving electronic engineering required to optimize the energy transfer from the roof top to the grid. This course covers the Fundamentals of grid-connected PV systems, with the aim of providing engineers with an honest overview of the technologies, topologies and electronics that structure such systems. Solar energy is extremely important means of expanding renewable energy resources. Solar may be a nonconventional source of energy, considering this we've developed solar panels in order that we will fulfil our electricity need. The problem above are often solved by our system by automatic tracking the solar power. The system architecture contains a LDR sensor senses max solar power. It is being given to the Microcontroller through the ADC.  In which digitizes the LDR output. The Motor is employed to rotate the LDR to sense the max solar energy. A Solar Tracker is essentially a tool on to which solar panels are fitted which tracks the motion of the sun across the sky ensuring that the utmost amount of sunlight strikes the panels throughout the day. After finding the daylight, the tracker will attempt to navigate through the trail ensuring the simplest sunlight is detected. The objective is to development of an automatic solar tracking system whereby the system will caused solar panels. It will keep aligned with the daylight in order to maximize in harvesting solar power.
