Sun Tracker Solar Panel Project

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.

Sun tracker solar panel project.

Build a sun tracking solar array in under an hour. The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. This sun tracker diy solar project will help us to achieve maximum power transfer at all times from the solar panels automatically by tracking the 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. Two light dependent resistors are arranged on the edges of the solar panel. Attach your two ldr s to each side of the solar panel east and west and solder one end of a jumper wire to each of their leads. 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.

Charge your phone with free clean energy. In this sun tracker circuit two ldrs are used to detect the direction of sun. Solar panel sun tracker phone charger fun and easy green robot.
