They're going to buy a 30 million dollar solar array for DOE? That buys a
pretty dang big array. If there are 1000 people in that building, that's
$30,000 for each person that they get off the grid.

$30ooo is what it would cost to provide off grid power for a small family.

3 1000 watt Bergey windmills + towers
Photowatt Kyocera BP or other photovoltaic panels - maybe a 3000 watt array
with mounting hardware
Bank of Rolls deep cycle 10 year guaranteed batteries (300 lbs each) + wiring
Trace 24 volt inverter, maybe a 48 volt system is available now
Service panel to connect house, well pump to power source at inverter
Underground drop from windmills and solar arrays (#2 copper)

For all this it could cost even more, maybe $35K-40K total cost for entire
system less house wiring.
This is the top of the line pricey system but very durable and reliable with
long service life;
no golf cart batteries.

And they want to spend $30000 per person, in a building-wide system, wen the
government is getting
the equipment at wholesale cost? What a ripoff for taxpayers.
