then again, if you had a gate opener at the end of 2 mile driveway that is
battery powered and no handy power line, it might be just the thing to get
to keep a small battery charged.

Absolutely correct. There is a definite niche for solar power, or
wind power, or for bicycle operated generators. Any place one needs
a continuously availble source of a small amount of power, solar will
do nicely.... usually.... except maybe in things like coal mines
(grin).....

However, if the purpose is to "get off the grid" and "replentish
the
earth" or some such, the operator needs to make a business decision
regarding costs, maintenance, reliability..... and solar isn't even
in the running to replace an existing grid source...... the ONE
exception
being on government buildings where taxpayer money is used to set
up a million dollar installation where the maintenance cost exceeds
the
electric bill.... Since the taxpayers are paying for it, and the
politician
can get a few votes from avid tree-huggers, it is cost effective...
