[RE-wrenches] Residential tracker that has horizontal axis in east-west orientation?

[Christopher Warfel]

Not too long ago there were postings about residential trackers. I put 
in a plug for Array Tech, but we are having a very hard time with 
getting information on the controller and how to get it to work for our 
case. I have moved the sensor every which way but pointing down....... 
Their controller comes from the commercial/utility side of the company 
and is designed to place as many modules on a foot print and eliminate 
shading which isn't an issue if you are putting in one single tracker.  
The horizontal axis is north south, and the modules move east west. The 
array is a  zero tilt which is non optimal for most of the year.  Does 
anyone know of a single axis tracker that is designed for east west 
horizontal axis so the modules can adjust throughout the day and seasons 
with the modules facing south?  Thank you, Chris Warfel
