Sun Tracker Solar Panel Project

The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller.

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. In this sun tracker circuit two ldrs are used to detect the direction of sun. 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. 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.

Light dependent resistors produce low resistance when light falls on them. The circuit design of solar tracker is simple but setting up the system must be done carefully. The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. 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. Charge your phone with free clean energy. The solar panels are normally oriented perpendicular to the sun for getting the optimal parameters.
