[RE-wrenches] Trackers

[Sindelar Solar]

Bill,

No, I'm with you on this.Given the the greatest boost (~+/- 30%) of 
daily tracking is during the summer and most stand-alone applications 
are winter-peak (where tracking adds at best 10-15%), seasonal water 
pumping is about the only time when small-scale tracking is justified 
over simply adding array. Any pumping where the source is slow enough 
that the length of the day becomes an important factor, like drip 
irrigation or a very low yield well or spring, is worth looking into. 
But that's about it in my experience.

Allan
