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.

Chris,
I thought since solar PV prices have come down (understatement), is it
not more cost effective to buy more modules than a tracker? Are there
scenarios that the above would not ring true? (As I remember, off grid
water pumping for livestock ponds may still be an exception as also,
limited space.) Please advise.
Thanks,

Dear people:
What trackers are y’all using nowadays?I have a customer (with a great
site) who’s insisting on a pair.We’ve sold Zomeworks and Array
Technologies in the past, but I know there are more offerings now.
Thanks for the input!
