I do off grid installs. I took a 'solar course' a while ago, was the only 'lectrician there, and subsequently have been involved since then.

There is a monetary aspect here, ( we are $.0117 KWH) as the 'bottom line' has attracted the mainstream public these days, as opposed to the sandal wearing dreadlock sporting crusaders of the past.

Our history here has gone 180 deg. from the Rural Electrification Program* , after WW2 I believe, when poco's would actually knock on your door selling themselves, to expensive line extentions ($11 OH $18 UG prim)

The inital poco install, plus monthly fees that can be easily amortized over , say a decade, justify quite the alt. power setup.

This, of course is most attractive to those whom choose house sites here waaaay out in the puckerbrush, many don't even realise when there's a power failure.
