Solar Trackers Increase a Solar Panels Electrical Output

Dual-Axis Tracking Generates More Power

By Mark Scanlon, CEO of Sedona Energy Labs   |   November 23, 2010
Dual-axis tracking systems generate more power than fixed arrays by continuously positioning the PV array so that the incident angle of solar energy is 0°.

While a tremendous amount of research and funding is going into trying to increase the efficiency of photovoltaic cells by a few percentage points, there is a readily available solution that yields a 40% increase in produced power today - dual-axis tracking [1]. By simply moving the PV array so that it is aligned with the sun throughout the day and seasons, you get a large boost in produced power at a small incremental cost. Of course the cost depends on the design of the tracking system. In today's market, this cost ranges from under a $1.00/produced watt, to around $3.00/produced watt. 

We are talking about produced watts rather than rated watts.
One of the drawbacks of most dual-axis trackers has been the pole-mounted design. A better design would be lightweight, low wind resistance, and no requirement for an extensive foundation to support it.
