 Solar trackers are a type of device with photovoltaic panels,
which accurately tracks the path of the sun throughout the day.
 This system follows the sun by moving in a single or double
axis.
 Generally, the inclination angle is adjusted manually at certain
intervals during the year and automatic movement is provided
in the east west direction.
 It adjusts the direction so that a solar panel is always
positioned as per the position of the sun.
 By adjusting the panels perpendicular to the sun, more sunlight
hits them.
 A single axis tracker movement is usually aligned in north and
south directions, allowing it to move from east to west.
 It enhances the efficiency of a solar system without having to
install more PV modules.

7. ADVANTAGES
1. More Productivity: Solar Energy trackers enhance the productivity
of solar panels. It is due to the elevated level of direct exposure to
sunlight. The productivity depends on the geographic location of
the installation
2. Simple and eco-friendly energy: This is a convenient system to
track the sun for better energy output. The increased output offers a
sustainable power source for our requirements.
3. Land Optimization: Solar trackers are significant land optimization
tools. They can generate more electricity than the installations
devoid of tracking systems and occupy the same amount of land.
4. Easy Monitoring: You can easily monitor the working of your solar
tracking system from your PC right away.

8. DISADVANTAGES
1. High Cost: Solar tracking devices are a bit more expensive. They
have a high initial cost as they have moving parts.
2. More Maintenance: Solar tracking systems demand more
maintenance. Though the requirements of maintenance depend on the
type and quality of the tracking system.
3. Site Preparation Requirements: All types of solar energy tracking
systems require significant preparation at the site of installation. It
includes additional trenching for wiring and grading etc.
4. Weather Constraints: It is not favorable in snowy weather. Such
tracking systems are only beneficial in hot climates.

10. FUTURE ASPECT
1. Single-axis and dual-axis photovoltaic tracking system, with appropriate control
systems, the electrical energy can increase from 22-56%, compared to fixed PV
system.
2. Combinations of microprocessor- and sensor-based control systems represent the
most commonly used control method as well as the most efficient.
3. Active tracking systems use electrical drives to move the axis, which can consume a
huge amount of electrical energy because of improper control systems.
4. Sensor-based photovoltaic tracking systems are more expensive because of
additional sensor devices, but provide lower tracking error (0.14), compared to
sensor less photovoltaic tracking systems (0.43-).
5. Electric motors used in PV tracking applications are exposed to weather conditions
and are therefore designed to withstand strong winds, and high temperatures and
humidity.
6. The most commonly used electric motor is permanent magnet brushless DC motors
as they are easy to maintain.
7. Novel innovative tracking systems will include dynamic weather forecasting and
cooling of the PV system with wind or water.

11. CONCLUSION
• It is designed according to the circuit to trap the sun in all
directions.
• It has better efficiency and sustainability to give a better output
compared to fixed solar panels.
• Thus, we can conclude that this device will play an important role in
day to day life especially in home and industrial areas.
