Abstract - A periodic tracking system for single axis
manual systems automated this system is needed to save human efforts and time.
motion gives the motion of angular lift to the collector. As the sun travels from east to west the trajectory of the sun changes every day by tilting towards the south direction. The tracking system is used to tilt the collector facing the south direction to keep it perpendicular to the sun by changing the tilt angle. This system will increase the efficiency of the collectors and will take the utmost use of solar energy. This system uses a chain sprocket mechanism to convert the rotational motion of the motor to angular lift motion to the frame. This tracking system can be used for any collector which requires an angular periodic lift to increase efficiency. The angular lift motion takes place as the frame is attached to hinges at one end and the other end is attached to a chain which has linear motion but as it is hinged at one end angular lift takes place. The tilt angle given to the system depends upon the latitude and date at which the collector is located.
2. AIMS AND OBJECTIVES Our aim is to design an automated tracking system which can lift the collector and keep it in the perpendicular direction of the sun which has a maximum intensity between 9am to 3 pm to gain the utmost use of solar energy. Our objective is to use advanced technology yet simple techniques to save human time and efforts by using knowledge gained so far. To save human time as well as unnecessary human efforts which would have been invested in trial-and-error methods, while optimizing the design and increasing the efficiency of collectors we are designing this tracking system with 1o accuracy from the required results. A ready-to-use system is made for industries to test different dates and according to the accuracy of the lift. By considering all the analytical aspects, this mechanism is quite simple yet durable.
Key Words: Tracking system, tilt angle, chain sprocket, Angular lift motion.
1. INTRODUCTION
3. LITERATURE REVIEW
The sun travels from east to west but actually the trajectory of the sun changes every day by slightly tilting towards the south direction which is for Pune. So, to make our solar collectors more effective the idea of a tracking mechanism is used.
Solar energy is renewable energy used everywhere, in this paper explanation of solar trackers and fixed PV solar systems and a comparison of the efficiency of single-axis solar trackers and fixed solar PV panels. Solar trackers produce electricity in large amounts because of their tracking technology, solar panels always track the sun as compared to the fixed mount PV system. The solar system produces more energy when the sun is perpendicular to the PV panel. At a perfect angle, the solar system consumes a large number of solar rays and produces electrical energy. Solar trackers can adjust their angle towards the sun automatically, therefore they produce more energy. Fix mount PV panels are constructed at a fixed angle so they cannot consume sun rays all day.
A periodic tracking system is a mechanism that is used to track the periodic motion of the sun and accordingly lift the frame. The main motive of this project is to give a single-axis motion to the collector by converting rotational motion to angular lift motion. This is achieved with the help of a Chain sprocket mechanism controlled by a stepper motor. The tracking system is used for angular lift motions, we are considering solar collectors as an example but this mechanism can be used for any collector in use of the periodic angular lift. India has the advantage of abandoning sunlight so to take utmost use of solar energy this tracking system is needed. As renewable sources are in need this will help in generating more energy in less time. Industries use large-scale solar collectors so to make
