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.
Sun tracker solar panel project.
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.
Two light dependent resistors are arranged on the edges of the solar panel.
Light dependent resistors produce low resistance when light falls on them.
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 circuit design of solar tracker is simple but setting up the system must be done carefully.
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.
Solar panel sun tracker phone charger fun and easy green robot.
The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller.
Charge your phone with free clean energy.
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.
