A DIY Solar tracker made from an arduino nano, 4 channel relay, DC motor, garage door worm gear, Light dependent resistors and a potentiometer.
Please feel free to message me for any questions :)
So why a tracker?
-For our capstone we needed a smaller footprint for the solar panels so we couldn't just add more panels.
-Single axis tracking is also cheaper than 2 axis tracking.
-The tracker is also built to "pulse" the motor incrementally, so it's not constantly on and using power.
-A worm gear design prevents back driving to have the panels "lock" in place so you don't have to apply any holding torque with the motor and consuming power
-The tracker uses potentiometers, standard DC motors, an arduino Nano, Light dependent resistors and a 4 channel relay that can drive up to 30V motors so its extremely cheap and allows for a high degree of customization.
-The cost of this prototype and the anticipated cost of the tracker system is lower than what is commercially available hahaha.
-The complexity of this tracker was built to be UTTERLY simple, cheap, and replaceable yet durable on purpose as it was meant for use in underdeveloped areas.
