Sun Tracker Solar Panel Project

Build a sun tracking solar array in under an hour.

Sun tracker solar panel project.

The circuit design of solar tracker is simple but setting up the system must be done carefully. Light dependent resistors produce low resistance when light falls on them. In this sun tracker circuit two ldrs are used to detect the direction of sun. The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller.

Arduino based sun tracking solar panel project using ldr and servo motor 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. Four ldrs and four 100kω resistors are connected in a voltage divider fashion and the output is given to 4 analog input pins of arduino. The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. Charge your phone with free clean energy.

The solar panels are normally oriented perpendicular to the sun for getting the optimal parameters. Solar panel sun tracker phone charger fun and easy green robot. To connect the panels into a string just solder the positive lead of one panel to the negative lead of the other which should leave you with a positive and negative wire left over.
