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.
Sun tracker solar panel project.
Light dependent resistors produce low resistance when light falls on them.
The solar panels are normally oriented perpendicular to the sun for getting the optimal parameters.
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.
Build a sun tracking solar array in under an hour.
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.
Two light dependent resistors are arranged on the edges of the solar panel.
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.
Charge your phone with free clean energy.
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.
The circuit design of solar tracker is simple but setting up the system must be done carefully.
