inside of about 20 minutes.( exterior temperature 30F) It had a solar
heater shower augmented by a tank and coil hooked to the stove.
We had two CFLs* off and on from about 7:00 pm to midnight for two days,
the radio and laptop about an hour a day. The place had led lights
anywhere they might be needed as a back up ( those stick anywhere LED
push button lamps with rechargeable batteries). If the amount of
sunshine was a problem it would be a simple matter of adding more
batteries or a more powerful panel.

But for those without grid?  I live in a part of the world where running
water is scarce and wind is spotty.  But there's lots of sunlight, average
insolation is nearly 5h/day here.  But it's the luck of the draw.  If you
live someplace with lousy insolation, you might not see the value in PV.

See above. With no grid electricity then it makes sense. Trying to *replace*
grid energy with PV solar is about as 'un-green' as it gets.

While Graham sees solar as absurdly expensive and inefficient way to
produce
electricity for those with grid electricity available. He fails to
accept that the cost of an "Available" grid connection may not be cost
competitive.

Back in 1986 grid connection was "Available" to me for a mere $6,000.
Some years later a customer of mine found that a grid connection was
"Available" for a bargain price of $8,000.

Availability of a grid connection is largely a moot point. The price
is the determining factor.
I mean really, which would you rather pay;
$6,000 for an "Available" grid connection vs $0,000 for an - for an
easy to design and install solar system.
Or perhaps $8,000 for an "Available" grid connection vs $2,000 for
an - for an easy to design and install solar system.

Perhaps Graham would like to point out the benefits of the "Available"
grid connection as opposed to the actual cash advantage of between
$6,000 and $6,000.
