I experience a difference in sun light hours of about 8 hours Summer verses Winter. Currently I manually turn 1 of my arrays a total of may be 240 degrees (E/W) in the summer. This works great! (when I remember to turn it!) In the winter I only need to turn it maybe 70 degrees (E/W) due to a hill and trees. I was wondering what the Maximum degrees the tracker can turn (E/W) Knowing this will help with my placement of a new array or maybe modifying a current one.
