Using Positioning Cables: The Pulley Principle

To turn the solar cells automatically to track the sun's progress through the heavens, we decided to use a set of positioning cables, with some help from a pulley and a counterweight. In our initial tests, we quickly learned that moving our turntables required more power than we could easily deliver. We turned to a construction that steered the central axles upon which the turntables pivot, and attached this assembly using a 10mm steel bolt.

This assembly let us change the orientation for both solar arrays in tandem about their axes. We were also able to put the coarse gravel with which our roof is covered to work for our counterweight as well.
