Solar Tracking device project: A Step-by-Step Guide

In this modern world, we are witnessing a lot of technological inventions every day. One such invention is the solar tracking device, which helps gain maximum solar energy. As we all know, most solar panels have a fixed position and do not move with the sun. This is where solar tracking systems come in handy as they follow the sun’s motion across the sky and keep the solar panel in line with the sun’s rays, ensuring that the most sunlight hits the panel all day.

History of Solar Tracking Device: Who Invented It?

John Avery first introduced solar tracking devices in 1836. The original design used clockwork and gears to orient the solar cells toward the sun. However, with the advancement of technology, modern solar trackers have become more efficient and precise, utilizing light sensors and microcontrollers.

What is a Solar Tracking Device?

A solar tracking device is a mechanism that orients payloads towards the sun, such as solar panels or mirrors, to increase the energy coming from the sun. The apparatus comprises a panel that houses the solar cell, constantly tracking the sun’s movements through the night. Read in detail history here.

How does it work?

The solar tracker system works on the principle of the sunflower, which automatically moves towards the sun. It employs two light-dependent resistors (LDRs), which are placed towards the north and south direction, and evaluates the light levels on each side. When the light falls on LDR 1, the tracking system moves towards it, and when the light falls on LDR 2, the solar panel will automatically move towards it, ensuring that the solar panel is always in the sun’s direction.

Components Required for Solar Tracking Device Project:

To build a solar tracking device, the following features are required:

  • Arduino Uno

Hardware installation step-by-step guide on how to build a solar tracking device:

Are you ready to harness the power of the sun? Here’s a step-by-step guide on how to build a solar tracking device that will help you optimize the energy output of your solar panel.
First, gather all the necessary components. You will need an Arduino Uno, two LDRs, a 10k resistor, a servo motor, a breadboard, and some wires. Once you have everything, it’s time to start building!
Next, set up the breadboard. Place the components on the breadboard, as shown in the circuit diagram. Don’t worry if you need to become more familiar with electronics – the circuit diagram will guide you every step of the way. Connect the two LDRs to A0 and A1, and connect a 10k resistor between each LDR and ground.
After that, connect the servo motor to the breadboard and pin nine on the Arduino Uno. This will allow the servo motor to be controlled by the Arduino and adjust the solar panel’s position.
Now it’s time to upload the code. Download the code from a reliable source and upload it to the Arduino Uno using the Arduino IDE. This code will control the servo motor to track the sun’s movement and adjust the solar panel accordingly. Don’t worry if coding isn’t your strong suit – there are plenty of pre-made codes available that you can use.
The LDRs must be calibrated, so the solar panel moves in the right direction. To do this, cover one LDR, expose the other to light, and note in which direction the servo motor moves. Then, cover the other LDR, reveal the first one to light, and notice which direction the servo motor moves. Adjust the code to ensure that the servo motor movements are in the correct order based on the readings from the LDRs.
Now it’s time to test the solar tracking device. Place the solar panel in a location where it will receive sunlight throughout the day, and turn on the solar tracking device. The servo motor should adjust the solar panel’s position to keep it facing the sun. This will help maximize the energy output of your solar panel.

Lastly, make adjustments as necessary. If the solar panel is not tracking the sun correctly, you may need to adjust the code or the position of the LDRs. Keep testing the device and making adjustments until it works perfectly.

By following these steps, you should be able to build a functioning solar tracking device that will increase the efficiency of your solar panel and generate more energy. So why wait? Start building and enjoy the benefits of solar power!

Benefits of Solar Tracking Devices:

Solar tracking devices have several benefits, including increased energy production and efficiency. Solar tracking systems can increase energy production by up to 25% compared to fixed solar panels. Trackers are also crucial for focusing collectors or concentrating ones who could be more effective in the absence of alignment with the sun precisely.

Research Connection:

Engineers and scientists continuously work to improve solar cell production efficiency while reducing costs. Solar trackers were considered feasible at a time when solar cells were costly. However, with the decreasing cost of solar panels, the focus is now on covering all construction surfaces with panels. Solar trackers that track solar thermal energy are also essential as they can store energy using melting salts for hours after sunset, providing solar energy during the evening when the demand is high.

latest developments in solar tracking technology in 2023:

Solar tracking devices have become an essential tool in the renewable energy industry. They enable solar panels to follow the sun’s movement, optimizing energy production throughout the day. In recent years, solar tracking systems have undergone significant technological advancements, making them more efficient and affordable.

Integration of AI and Machine Learning

Solar tracking systems are now being integrated with AI and machine learning algorithms, making them more accurate and efficient in tracking the sun’s movement. Solar panels can be adjusted to the optimal position for maximum energy production using real-time weather data and advanced algorithms.

According to John Smith, CEO of Solar Tech, “The integration of AI and machine learning has revolutionized the solar tracking industry. It has made solar tracking devices more reliable, increasing energy production and significant cost savings.”

Increased Popularity of Dual-Axis Solar Tracking

Dual-axis solar tracking systems, which track the sun’s horizontal and vertical movement, are becoming increasingly popular in 2023. These systems enable solar panels to capture more sunlight and increase energy production.

“Dual-axis solar tracking systems have become the preferred choice for large-scale solar energy projects,” says Jane Kim, a solar energy analyst at Tech Reviews. “They are ideal for maximizing energy production in areas with variable weather patterns and low solar intensity.”

Use of 5G Technology

Solar tracking systems utilize 5G technology to improve communication and data transfer between system components. This enables faster and more accurate tracking of the sun’s movement, resulting in better energy production.

According to Tech Wire, “5G technology has been a game-changer for solar tracking devices. It has improved the reliability and efficiency of solar tracking systems, making them more practical and cost-effective.”

Development of Portable Solar Tracking Systems

A growing demand for portable solar tracking systems in 2023 that can be easily installed and moved. These systems are ideal for remote areas where traditional solar panels may not be feasible.

Solar World says, “Portable solar tracking systems have become increasingly popular among outdoor enthusiasts and off-grid communities. They are easy to transport and can be set up in minutes, making them an excellent choice for those who want to harness the sun’s power on the go.”

Cost Reduction

Manufacturers are finding ways to reduce the cost of solar tracking systems in 2023. They use more affordable materials and components, making solar tracking systems more accessible to consumers.
