Its a disgrace what the goverment is doing. Giving $8k to families who earn
under $100k so they can put in 1kw is absolutely rediculous. The difference
once you go from $99,999 to $100,001 is stupid. A 1kw system typically costs
$12k, but only $4k on the rebate.. a 66.6% discount, thats rediculous. The
people who earn over $100k have to pay 3 times as much, not to mention that
its their taxes paying for the other people anyway.
What the goverment doesn't understand is that the price of panels are largly
set by the price of existing electricity. WIthout the repayment its about20
years until it pays off, most studies show solar panels aren't even carbon
neutral until 15 years, 30 years if the water used to make them comes from
de-sal. They are just a joke - like water tanks.
I wouldn't buy them for "carbon" purposes - the whole AGW scam is just
a crock of bullshit anyway.
The panels could be useful for emergency power - once the state
governments/greenies and the economic crisis inevitably run the
electrical (and every other) infrastructure into the ground and we
have constant daily blackouts / shortages.
For example, a 1kw unit could run a small refrigerator for several
hours a day, and charge batteries for running modest lighting / small
TV / laptop and ADSL box etc in the evening.
A generator would be needed as backup though, but to fuel the thing
all day wouldn't be cheap. The solar system would probably save money
in generator fuel ?
Agree on the tank theory too. since the average household supposedly
uses 1 kl per day, ( 1 kl = $1 on our local water rates) and the
suggested tank capacity (local council building regulations for all
new homes) is 5000L, the tank holds $5 of water - or 5 days with
normal family use.
If it rained enough every 5 days to fill the thing, then you would
save your entire water rate charge, ($365 a year based on above
figures). in 10 years you might have the cost of your tank and its
related pump / plumbing repaid - not counting interest etc.
In a normal world - where we currently live right now - where there
is 24h water and electricity, both of these items are financially
impractical.
In a future world where we are screwed with carbon taxes etc, it might
be a different story
