For a photovoltaic solar panel, following the sun’s path across the sky raises efficiency by 30-50%. This DIY sun tracker is the latest addition to our DIY Free Energy projects and uses a combination of a sensor and linear actuator to track the movement of the sun.
The 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 liner actuator that starts moving the photovoltaic frame with the help of the wheels.
After sourcing the solar panels, the solar PV tracker is not difficult to build. 12 Volt linear actuators are available on eBay. Then, just salvage a pair of strong wheels and all that’s left is the wooden frame.
