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.

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.

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.

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!
