Solar Tracking Mounts

According to Renewable Energy World magazine, "The numbers are latitude-dependent, but compared with modules fixed at the optimum angle, single-axis trackers typically increase electricity output by between 27%–32%."  Additionally, in the case of battery-based solar systems, there is an advantage to extending the time of maximum charge current throughout the day.

A SunArx® solar tracking system consists of any number of T-21 mounting racks and enough C-6 control boards to control them.  Each C-6 control board controls up to 6 T-21 racks.

"Paula Mints, principal PV analyst at Navigant Consulting, has reportedly forecast that between 2009 and 2012, tracking systems will be used in at least 85% of PV installations above 1 MW."  We have spent years evaluating existing racking products and trackers, and we have designed a mounting solution that is what we would want to install, and what we would want to own.

Below is live data from our test site in Colorado, with identical modules and inverters, fixed mount vs. solar tracker. More details on this system can be found in the forum.
