3. Introduction 3 Solar energy is rapidly advancing as an important means of renewable source of energy. In verge of a major energy crisis, as energy consumption is increasing day by day and energy sources depleting. Solar energy is universally accepted renewable energy source, which can used to avoid the energy crisis. An eco-friendly method of utilizing solar energy for maximum energy consumption is dual axis solar tracker. Dept of ME , GMIT, Davangere

4. 4 Dept of ME, GMIT, Davangere What is solar tracker? Solar tracker tracks maximum solar energy. This energy can used by converting it into other forms. Solar tracker is the device which orients solar panel towards the Sun or light. The orientation is due to Light Detecting resistors.

5. To design and construct a simple solar tracking system which can absorb maximum amount of sunlight. To generate power from solar panel using dual axis tracker. To make electricity accessible remote areas. 5 Objectives of the Project Dept of ME , GMIT, Davangere

6. 6 Methodology of Work Block diagram: Circuit diagram: * We need to develop a prototype of two-axis solar tracking system based on microcontroller. * Light dependent resistors are used as sensors. * The resistance of LDR decreases with increasing light intensity. * Four LDRs are used for detecting the direction of light. Maximum energy is absorbed with higher efficiency . Dept of ME , GMIT, Davangere

7. Arduino uno: The Arduino uno is a microcontroller board based on ATmega328. It has 14 digital inputs/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, 16 MHz Ceramic Resonator, a USB connection, a power jack and a reset button. It has a number of libraries, including one for servo motor control. The input supply needed is ideally 7-12V DC. Servo motor: Servo motors run using a control loop and require feedback of some kind. They are generally an assembly of four things: a DC motor, a gear set, a control circuit and a position sensor(usually a potentiometer). Since servo motors have a control loop check what state they are in, they are generally more reliable than stepper motors. Servo motors require a control PWM signal that represents an output position and applies power to the DC motor until the shaft turns to the correct position. Determined by the position sensor. 7 Dept of ME , GMIT, Davangere

8. LDR: Light dependent resistors work on the principle that, if intensity of light on it increases, its resistance decreases and thus more current flows through it. Bigger LDRs have higher sensitivity. Solar panel: Solar panel are used to convert light from the sun, which is composed of particles of energy called "photons", into electricity that can be used to power electrical loads 8 Dept of ME , GMIT, Davangere

9. 9 Dept of ME , GMIT, Davangere Expected Outcome of the project Dual Axis Solar Tracker project is to provide an efficient solar distributed generation system. At maximum, the solar tracker is perpendicular to the light source. The built system has a calculated annual energy gain of 48.982% compared to an immobile solar panel. Compared to a single axis tracker, the dual-axis tracker has an annual energy gain of 36.504%. The purpose of a solar tracker is to accurately determine the position of the sun. This enables solar panels interfaced to the tracker to obtain the maximum solar radiation.

10. 10 Dept Dept of ME , GMIT, Davangere Application of the Project Dual axis sun tracker can be used for large & medium scale power generations. It can also be used for power generation at remote places. It may be used as domestic backup power systems. It can be used in solar street lighting system. It may be used in water treatment technologies and solar heating.

11. 11 11 Conclusion We presented a means of tracking the sun's position with the help of microcontroller. Specially, it demonstrates a working solar tracker for maximizing solar cell output by positioning a solar panel at the point of maximum light intensity i.e., when Panel is Perpendicular to the Solar energy. Solar tracking system is more efficient than any other ordinary panel. It is possible to reduce the energy crisis to some large extent. Dept of ME , GMIT, Davangere
