<DIV>Yes, grid tie is dependent on the grid itself, grid power goes down the
inverter shuts down to avoid backfeeding the grid. The only solar system
that works when the grid is down is multi mega thousand dollar systems with
battery banks and big inverters.</DIV>

<DIV class=plainMail>> Where are you buying solar that cheap??
<BR>> Last I priced it, about two months ago, <BR>> it was
something on the order of $3 per <BR>> watt, I don't see where you're
coming up <BR>> with $.07 per kWh...<BR><BR>I found it hard to
believe too, but the StarCity ads on the radio around here are saying
you can install solar for LESS than you are paying now to the utility,
and we are paying 10 cents (unburdened), more like 15 cents with all
charges thrown in to the utility.<BR><BR>These quotes are for "leased"
systems. you sign up for 20 years of electricity at something like
7.5cents per KWH and they install the grid-tie system on the roof of
your house. THey own it, and you are fixed at 7.5 cents for the 20
year life of the lease. <BR><BR>[I have not seen this figure
directly, but one of the email responses to this thread quoted his costs
of 7.5 cents per KWH for a leased system. But I cnnot now find his
email.]<BR><BR>The leasing companies are betting the cost of electricity
goes up, and the amortized cost of the solar panels will be less than
the increasing coal rates and since they keep the difference, it is a
good business model.<BR><BR>The problem is most people do not think
about the time-value of money. And only think in terms of
month-to-month bills. Investing in a solar array is still a large
upfront cost. But it is like buying a house with a 20 year
mortgage. You will pay less for the house overall than you would
ever pay if you rented it for 20 years.<BR><BR>Investing in solar panels
is the same thing as buyihg a house. Staying with the utilities is
like renting for life.<BR><BR>This new lease solar system lets people
avoid the up front investment, and it still gives them the lower total
costs, but the leasor who DID make the investment also makes
money.<BR><BR>I paid up front for my system, but since the pay back is
now down to less than 7 years, by the time 20 years rolls around, my 20
years of free electricity will have saved TRIPLE the upfront
cost.<BR><BR>Here are the three options:<BR><BR>People who lease solar
will get 7.5 cent electricty for 20 years... <BR><BR>People who buy
solar, will get free electricity for life which in seven years or so
completely pays back the investment and then it is free for life..
A huge payback.<BR><BR>And those who do nothing, will face 20 years of
escalating energy costs and be paying probably 4 times more over the
same period.<BR><BR>Something like that.<BR><BR>Bob,
