If you spend a ton of money on solar panels just to have they sit stagnate as the sun tracks trough the sky, you could be losing some cold hard cash.

Instructables has a Do-It-Yourself (DIY) solar tracker that takes some easy obtainable parts and combines them to make a very inexpensive solar tracker, which could improve your solar panel efficiency by as much as 30-50%.

DIY Solar Tracker Parts List

Several treated 2×4’s (Lowes)
Two wheels from a free bicycle- free or almost free bikes are pretty easy to find from the local landfill or thrift store
A piece angle iron with pre-punched holes (Lowes)
A 12 volt linear actuator-(~$75?)- (Ebay)
An LED tracking sensor- (~$40)( http://www.redrok.com/led3xassm.htm#led3xforsale )
Various nuts, bolts, screws, cable and wire -(scrounging around my workshop)

Fun and easy little solar project from the makers shed, powered by the sun.

The kit comes with detailed instructions, and is easy enough for even a beginner to assemble. I really like the contoured circuit board, especially the gold flames. It really was amazing how fast this little solar racer ran across the floor after just a minute or two of charging.
