Check out the cool DIY solar panel that follows the sun’s path across the sky to raise efficiency by 30-50%. Building a sun tracker is easy and can help you stay less reliant on the grid during the colder months due to the different placement of the sun.

This solar panel sits on a wooden frame which is mounted on two bicycle wheels. A sensor tracks the path of the sun and sends the signal to the linear actuator that starts moving the photovoltaic frame with the help of the wheels. Sounds complicated but it really isn’t.
