[RE-wrenches] Trackers

[Dave Angelini Offgrid Solar]

I like Array Tek and for offgrid. It is a waste to dual axis track. Less
is more! All you need is the array point at the sun with enough tilt to
shed snow. Again, Less is more. If it had a failure (and none of mine have)
it is still a fixed array until it is repaired.

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.

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, Bill Loesch Solar 1 - Saint Louis Solar 314 631 1094

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!
