But so many unanswered questions!!!!!!

1) Living where there is sufficient sun? How many days per year?
2) Cost of batteries to store power during day for use at night etc.?
3) First cost of solar cells? Even if at one dollar per watt probably
a first cost of $3000 or so?
If solar cells cost five dollars per watt then $15,000?
4) If self installing; cost of inverter to turn battery electrcity
into usable AC 'mains type' electrcity?
5) other costs, wiring etc.
6) If planning to sell surplus power, produced by solar, back into
local electricity grid; what rate will power utility pay.
7) One estimate; to produce any appreciable amount of power in a
suitable climate ranged upward from $10,000?

A local ad. here showed an 180 watt solar panel selling for $800, on
sale. Since it s frequently cloudy here that might produce, say 90
watts-per hour, during the day, some days. That's not enough to
warrant large expenditures. For each $1000 of outlay, one can buy a
third or more of a year's electricity and that includes heating of
this all-electric four bedroom home in a cool climate with a long
winter.

Contrary opinions welcomed.


A 6KW system for a home costs about $48K. This means that it is
totally unviable compared to other electricity generation options.
The only way it becomes viable is for the govt to hand out more money
to get you to install one. After the gov pays for around half of the
cost, then it can make economic sense for the homeowner. For the
taxpayers, it's a loser.

In general, people aren't stupid. If solar energy was cost effective,
we'd
all be tripping over each other to get it.


It's very cost effective on my boat!

I'll bet there are lots of other places where it is cost effective.

My point exactly, in the scheme of electrical usage, your boat isn't even
on
the meter



There are many places where power lines don't reach.

And for those that need real electricity in those locations, God created
diesel generators
