$2500.00 deposit loss of interest @ 5% average rate 12 months $412.50 my loss
Cost and Loss total $895.50 divided by $0.60 = 1492.5 KW breakeven
4.08 KW per day 365 day approx breakeven
Winter average currently 3.4 KW
System faces west not optimum eg north facing.
Also did the solar hot water rebates $1600.00 federal and $500.00 state
Installed 63 days ago all refunds received.

I don't blame you for installing this as for *you* it makes sense but
remember SOMEBODY has paid the *real* cost of the installation which
looks to be around $10,000. Around $1500-2000 gets you your share of
a coal fired power station and it will produce 1KW for you all the
time. i.e 24Kw-hr a day.
Wind and solar make sense when you don't have grid access. If you do
have grid access and the green loonies won't let investment be made
in sufficient and reliable power stations then you might consider a
petrol generator for the odd outages.
Solar cells on gliders, yachts and spacecraft along with
communications repeaters in remote areas are a rational engineering
solution. However if you look at the comments on the WUWT article,
one guy is an engineer who did the life cycle energy costs of the
solar PV and wind generators and came to the conclusion that solar
returned just under half of the energy investment and wind slightly
less than 0.3. So neither is really an energy source as your up front
and maintenance energy investment is 2 to 3 times what you get out
over the life of the generator. Lucky we're a rich society to afford
these sorts of hobbies - or were, until this foolishness came along.
