Here’s a really cool project that can complement any of your future solar projects.  It’s a solar DIY that shows you how to make a solar photovoltaic tracker that will follow the sun’s angles, thereby increasing the efficiency of your solar cells and more energy produced.

For a class project (PV Design, Appalachian State, Dr. Dennis Scanlin) I decided to try making a low cost PV (photovoltaic) tracker. Being able to follow the sun’s path through the sky can raise your solar panel system’s output considerably (30-50%), but the argon filled ones can be a bit pricey, and seem to be a bit unsteady in wind. I looked at several different designs, looked at what materials I could find, and this is how I did it.
