Rotating Solar Panel Using Arduino

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.

Rotating solar panel using arduino.

The downside is that if the power from the solar cell dips below 3v the leds will turn off. Also there would be no need for the wasteful voltage booster. The battery will only pull down the solar panel voltage while. If this is a problem for you use power from the arduino to run the led volt meter.

It s purpose is to hold the the solar panel up and allow the microservo to adjust its tilt without falling over. In general with solar panels it is cheaper to use a bigger panel than to use clever tricks to get more from a smaller panel. Why not use 3 or 4 aa cells for a higher voltage that more nearly matches the solar panel. Rotating the panels to the east and west can help recapture these losses.

The rotating solar panel using arduino project aims at charging a 12vdc battery with the help of a solar panel mounted on platform which can rotate with the help of a motor. The upside to this is that you don t need extra batteries or jumpers. Attach the solar panel to the top of the t i did this with cardboard strips and strong adhesive. This motor is getting controlled by atmega328 microcontroller mounted on an arduino uno board which is in turn mounted on the pcb.

Lastly attach the microservo s gear to the side of the arm. Use an arduino two small servo motors with light sensing photo resistors to steer a solar panel towards the sun. This motor is getting controlled by atmega328 microcontroller mounted on an arduino uno board which is in turn mounted on the pcb. A solar panel in a fixed orientation between the dawn and sunset extremes will see a motion of 75 degrees on either side and thus according to the table above will lose 75 of the energy in the morning and evening.

To do this put two strips of wood into a t shape. The rotating solar panel system scans from one horizon to other to know the current position of sun and hence the position from which the greater solar energy can be harnessed. 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 provide the supply the maximum power.
