Middlebury College has recently constructed a solar farm consisting of 34 sun tracking solar panel arrays producing up to 136 kW of electric power, approximately offsetting the energy consumed by Battell Hall. Solar tracking allows a solar panel to yield up to 45% more energy. The Middlebury College solar trackers use their geographic location to calculate the Sun's apparent trajectory through the sky. While this approach is effective, there are other Sun tracking approaches. I have designed and built a light sensor based tracker to compare the effectiveness of the two tracking methods.
