Solar Tracker Using Dc Motor

In the setup function we set the pins were the ldr are connected as inputs and position the servo motor at 90 then wait for a 2 seconds before the code execution inside the loop.

Solar tracker using dc motor.

For example with a motor integral canopen network interface up to 127 bldc motors can be daisy chain controlled over a 500 m 1 640 ft long bus running at 125 kbd 5 km at lower baud rate using simple inexpensive yet robust twisted pair cabling with a shield. We have designed a single axis solar tracking system. In the loop we read the values received from our 2 sensors and adjust the solar panel based on these values. And a micro servo motor sg90 to control the solar tracker according to the horizontal axis which is the up down servomotor.

The solar panel tracker is designed to follow the sun movement so that maximum light intensity hits on the solar panel thus increasing the power efficiency. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. However conventional dc motor drivers used in solar tracking system do not provide. To track the sun i used four ldc sensors and arduino compares the data from them to rotate the panel in the direction with the most sunlight using two dc motors one for each axis and motor driver.

Solar trackers rely on a direct current dc motor driver circuit to control the movement of the solar panel. Each motor can then close current position and velocity loops on its own. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position. In this article we are going to make a sun tracking solar panel using arduino in which we will use two ldrs light dependent resistor to sense the light and a servo motor to automatically rotate the solar panel in the direction of the sun light advantage of this project is that solar panel will always follow the sun light will always face towards the sun to get charge all the time and can.
