Automatic Dual Axis Solar Tracking System

The Implementation Analysis Of Automatic Dual Axis Solar Tracking System is developed to automatically adjust the solar panel to high-intensity ray of the sun direction using Atmega328p

This project involved both simulation design and mechatronics implementation of a solar tracking system that ensures that the solar panel is perpendicular to the sun to obtain maximum energy falling on it.

The unique feature of this project is that it takes the sun as a guiding source by actively monitoring the sunlight and rotating the panel towards the direction where the intensity of sunlight is maximum.

The light-dependent resistors (LDRs) are the sensors that play the role of continuously monitoring the position of the sun which changes the position of the solar panel by switching on and off the servo motor.

The Atmega328p logic circuit fetches the input from the LDR sensor and gives the command to the servo motor to rotate in order to position the solar panel in the direction of the sun. This has enabled this project to generate additional energy of around 15% to 25% with very low consumption by the system itself.

The dual-axis sun tracker was designed and when tested for the power output of the solar panel, it was found that on average the solar panel would achieve maximum power generated from the hour of 10:00 am to 4:00 p.m, where 4.92W was stored at 10:00 am, 4.80W at 11:00 am, 4.92W at 12:00 pm, 4.68W at 1:00 pm, 4.88W at 2:00 pm, 4.87W at 3:00 pm and 4.93W at 4:00 pm.

Which was a much greater output as compared to a fixed solar panel which achieved maximum power output between hours of 12:00 pm and 1:00 p.m.

The dual-axis sun tracker would be recommended for use in solar power generation because it increases the efficiency of the solar power generated, and it’s cost-effective.

Automatic Dual Axis Solar Tracking System FAQ

What is an automatic sun tracking system?

The Automatic Sun Tracking System (ASTS) was made as a prototype to solve the problem, mentioned above. It is completely automatic and keeps the panel in front of the sun until that is visible. The unique feature of this system is that instead of taking the earth as its reference, it takes the sun as a guiding source.

Which motor is used in solar tracking systems?

Motor types used in solar power applications run the gamut. AC induction motors have been used in early solar tracking systems because they can draw power directly from the grid, but it is difficult to control AC motors at slow speeds necessary in most tracking applications

What is the difference between single-axis and dual-axis solar trackers?

A single-axis tracker moves your panels on one axis of movement, usually aligned with north and south. … A dual-axis tracker allows your panels to move on two axes, aligned both north-south and east-west. This type of system is designed to maximize your solar energy collection throughout the year.

Do solar panels rotate with the sun?

Click here to read! Trackers direct solar panels or modules toward the sun. These devices change their orientation throughout the day to follow the sun’s path to maximize energy capture. … Single-axis solar trackers rotate on one axis moving back and forth in a single direction.

How long do solar panels last?

About 25 to 30 years: But the solar panels generating that power don’t last forever. The industry-standard life span is about 25 to 30 years, and that means that some panels installed at the early end of the current boom aren’t long from being retired.

Do solar panels work at night?

Do solar panels work at night? The answer is no, they don’t. As we mentioned earlier, solar panels need light — preferably sunlight — to create energy. Although they can generate some energy from other light sources such as street lights and even the moon, the output is very low

What is the most efficient solar tracker?

Single-axis trackers are nearly 32.17% efficient compared to a fixed solar tracker mount panel. These trackers follow the Sun from East to West, providing consistent power output all day long. The trackers generate 15-16% higher annual power as compared to a static station of the same installed capacity.
