Increasing the efficiency of solar panel by solar tracking system

Abstract

Solar energy is a promising sustainable power source asset. If the solar panels have an opposite profile to the beams of the sun it will create more vitality. The objective of the work is to track the sun, so that the rays of sun will always be in perpendicular with panel. As the cost of manufacturing the solar tracking setup is high, there are alternative less expensive choices that have been proposed. This works aims to design and develop a model of solar tracking system. ATMega328P micro controller is utilized for the manufacture of control circuit. Light Dependent Resistors (LDR) is utilized to recognize daylight which impels the servo motor to turn the solar panel. The solar panel is kept in a region of most extreme exposure to daylight. Greatest torque and speed are achieved by a servo motor. Servo motor is most efficient with the scope of 80-90%. Servo motors are free from vibration issues. Execution and attributes of solar panel are examined tentatively. solar cells made of Silicon produced an maximum efficiency of 20%. Most of the solar panels still operate at level less than 40%. Because of their reduced performance. The initial cost increases due to the purchase of large sized panels, else the number of panels has to be increased. The efficiency and cost of the panel is inversely proportional to each other solar tracking finds a better way of improving the performance without increasing the rate of the panel. The area of exposure to sunlight is increased. Classification is based on the number of trackers single axis trackers are less efficient than Dual trackers A single tracking system is used. It is cheaper, less complex to install and still achieves the required efficiency. The increase in the initial setup cost is negligible when compared to the increase of power output. Maintenance costs are not high.
