When the power company started to pay for our carbon credits as well it became advantagous to maximize the arrays output. So we removed the old pressure treated frame and mounting system and attached the panels to this passive tracker. During the course of the day, the sun heats the side in the sun and drives a fluid to the cooler shaded side, thus causing the tracker to slowly rotate during the course of the day and keep the panels in almost direct light all day. On the old mounting system we averaged 9.17Kw a day, so far with the new tracker we are averaging around 14Kw a day, and have seen single day out puts as high as 18KW.

FUN FACTS:
The panels now sit 6 feet up in the air, the weight of everything above ground is just over 1,000 pounds, the mast the the tracker is an 8" pipe buried in a 5'x3' footing in the shape of an inverted mushroom, anchored by 2,400 pounds of concrete. In the morning the system resets itself from facing west to facing east in just over 15 minutes
