Abstract - Solar energy is more rapidly gaining popular as
an important means of increasing renewable energy resources. Our project will include the design and construction of a microcontroller-based solar panel tracking system. Solar tracking receives more energy from sun because the solar array is able to remain inclined to the sun. Solar tracking system is the most appropriate technology to enhance the efficiency of solar cell by tracking the sun. This paper aims at the development of a simple process to track the sun and attain maximum efficiency using Microcontroller Key Words: Solar Energy, Tracking, Solar Panel, 8051 Microcontroller, RTC.
1.INTRODUCTION The total populace is expanding step by step and the interest for vitality is expanding as needs be. Oil and coal as the primary wellspring of vitality now days, is required to wind up from the world amid the current century which investigates a significant issue in giving the humankind a moderate and solid wellspring of vitality. The need of our own is renewable vitality assets with modest running expenses. Sunlight based vitality is considered as one of the principle vitality assets in warm nations. As a rule, India has a generally long sunny days over ten months and halfway shady sky for a large portion of the times of the rest two months. This makes our nation, particularly the deserts sides in the west, which incorporate Rajasthan, Gujarat, Madhya Pradesh and so on extremely rich is sun based vitality. Many ventures have been done utilizing photovoltaic cells in gathering sun based radiation and changing over it into electrical vitality however the vast majority of these activities did not consider the distinction of the sun edge of frequency by introducing the boards in a settled introduction which impacts exceptionally the sunlight based vitality gathered by the board. We realize that, the edge of slant ranges between - 90 degree after sun rise and +90 degree before sun set going with zero degree at twelve. This makes the collected solar radiations be 0% at the sun rise and sun set and 100% at noon. This variation of solar radiations collection leads the photovoltaic panel to lose more than Š 2017, IRJET

40% of the collected energy. In July 2009, India unveiled a US$19 billion plan to produce 20 GW (20000MW) of solar power by 2020. Under the plan, the use of solar-powered equipment and applications would be made compulsory in all government buildings, as well as hospitals and hostels. On November 18, 2009, it was reported that India was ready to launch it National Solar Mission under the National Action Plan on Climatic Change, with plans to generate 1000 MW of power by2013 The day by day normal sun based vitality occurrence over India fluctuates from 4 to 7 kwh/m^2 with around 15002000 daylight hours for each year (contingent on areas), which is significantly more than current aggregate vitality utilization.
2.METHODOLOGY In the block diagram shown in fig.1 shows the complete structure of the tracking system the solar panel is kept on the frame which is rotated by using stepper motor. The stepper motor is connected to the microcontroller. By using the real time clock microcontroller gives the angle to the stepper motor gets rotating as per given angle of inclination. There are mainly two poles of structure one is stationary and other is moving. Now by using moving pole we can adjust the axis of rotating panel. The stepper motor is placed at fixed pole.
