Jay is correct about the economics, but sometimes we must live with them as the
only way to increase daily water production. However when the tracker fails
they will not be making the daily need anymore and it is far more likely to be
left dead than even batteries. In developing communities I have often used a
"village tracker", a manually tracked array that anyone walking by can move to
the sun. Along the line of Buddhist Prayer Wheels that are kept spinning by
passerby's. As an aside I once did a 40kW grid-tied PV system for a temple to
offset the load of the countless motors spinning their Prayer Wheels (not
enough people passing to keep them all spinning). From the Solar, Wind and
