Installing Solar Electric Since 1983


Can you identify the tracker shown below?
There are two identical trackers shown. Click any thumbnail for a larger image.
Description: These are single-axis trackers without out any means to tilt the fixed axis. Normally a single-axis tracker would have provision to tilt the North-South axis to compensate for latitude and season. These trackers do not have that capability.
Which direction should the axis be oriented? Can you provide a manual?
