INTRODUTION The electricity is generated by developing the photovoltaic material and subsequent development of solar cell- a semiconductor material that converts a direct light in to the direct current. By using solar arrays a series, a series connected solar cells generated a dc voltage that directly connected to the load. This alternative power source is in the recent years achieving a greater popularity especially the realization of shortcomings of the fossil fuels and other generating of energy resources. The use of renewable energy to generate electrical energy by recent to 00 of years. By using this system we can reduce the converter losses, storage losses and light gathering losses. The light gathering is dependent on the angle of incident of sun rays and the solar cell surface, when the sun rays are perpendicular to the surface of the solar plate then the efficiency of the solar cell is maximum. The main objective to create this system to reduce the incident angle between the sunrays and solar cell.. ANGEL OF ROTATION Total angel of rotation in Hours = 0 Degree So angle of rotation in hr. = 0/ = Degree Hence we give hr Delay to dc motor by programming of microcontroller and panel rotate every one hour and panel adjust perpendicular to the sun rays.

. Description of ircuit Diagram Fig No. shows The Actual circuit of the solar Tracking system Project, and the Working of the system is given below The RT Gives Real time clock pulse signal on hourly basis to the microcontroller and microcontroller detect this signal and operate the D Motor through the L Driver I Then solar panel rotate at appropriate speed set as per microcontroller programming and it holds the solar panel perpendicular to the sun rays whole day, and gives maximum power output as compare to fixed panel. Solar panel will convert sun rays into electricity. Battery will be charged through solar panel. Stored charged will be used as a power source for working of circuit. RT will continuously detect time and will provide signal to micro-controller. Micro-controller will drive the motor as per table. The time will be displayed on the LD display connected to micro- controller. By using inverter we can connect A load to system..

From the above graph we can see that the tracking system gives maximum power output between am to pm. And other graph show the maximum output only pm to pm. So the we conclude that the tracking system is better energy efficient solar system than fixed panel system.. ONLUSION A solar tracking system is design to employ the new principle of self-adjusting features of solar cell as a light sensor as well as providing various indications of their relative angles to the sun rays by detecting the voltage output. By using this system we can increase the efficiency of the solar cell 0% more than the tracking system..
