Wrenches, Happy Earth Day! Thanks to all who responded with info on the Wattsun trackers. Sounds like a good product and company which can be relied on. The specific application is a large array so the larger 225 sq ft configuration would be needed (in multiple). I note the documentation recommends equal length of pole above and below the ground, and the pipe size is specified as "call". My configuration would require 8' minimum of pipe above ground. Any advice from those who have installed the larger configuration on footer sizing and pipe sizing which might help me with bidding the installation?
