Just one note - if batteries fail - no, make that <i>when</i>
batteries fail - the system is dead. If a tracker fails, the system
continues to operate at a reduced output. So the risk is reduced. I,
too, would prefer a fixed array, but a tracker is a concession to
their gpd request.<br>
<br>
In this application - fairly low latitude, warm climate - a
Zomeworks passive tracker ought to be a good choice. Pretty
reliable, no electronics, and if it does fail ropes can face it to
the sky.<br>

<div>I strongly agree with the "no batteries" approach. All issues
mentioned come to fruit and in far too few years those batteries
will be abused to toast and now the system will sit for a very
long time if not forever and no water for the community. Your
best options are to live with what you can get PV-direct (I'm
even hesitant to use trackers in these applications) or drill
additional wells nearby if you cannot stack pumps in the well
with minimal drop pipe sizing or larger boreholes.</div>

<div>On a side note, I'm always hearing from remote folks that
they cannot get distilled water and are forced to use whatever
and those that can pay through the nose for tiny red bottles of
it. I point out that it falls for free from the sky whenever it
rains - collect it!</div>
