In this video NightHawkInLight demostrates a simple autonomous solar tracking system that can be used with solar panels or parabolic mirrors to improve their performance in producing renewable energy.

For this system I use two 10rpm, 6v geared electric motors, and four 5v, 0.6w solar panels connected in a configuration that allows the motors to constantly move the panels into shade purchasing links for these items below.
The cost of the electronics was about $10, and could easily be scaled up or down as necessary for a variety of solar applications.

The good thing about this solar tracker is that it doesn’t need any GPS signal or computers to work but, instead, simply “follows” the movement of the sun using small light sensors throughout the day!
