cost per kWh [RE-wrenches]

[Jeff Clearwater]

<x-flowed>
Our quoted /KWhr estimates range from $.17/KWhr over 20 years after 
state rebates for large grid tie systems in sunny climes to over 
$1.50/KWhr over 15 years without rebates with batteries for small 
off-grid systems in cloudy climes.

So it totally depends on your climate, system, assumptions,  rebates, 
and how you figure it and of course your margins.

peace,

Jeff C.
