how about some numbers,

how many kW does your system produce peak?
how many kWh do you use a day?
how much did it cost you to install?
what subsidies did you get?
how long will it take you to break even?

Article in local paper about installing system in a church.
They said half the cost of $738,000 was subsidized by a state grant and
it would pay for itself in 10 years.

There was a similar article about a home owner doing it a few years ago.
Can't remember subsidy but they said it would take 30 years to recoup.- Hide quoted text -

May well be right. There was previous scheme over here where they
subsidised installations in private homes. But our gov. is bust now.
So they are doing this scheme that costs them nothing now.
There is a new scheme coming out next year to encourage heat pumps &
solar thermal. I'm looking out for it.

I have a proposal on my fridge for 2.3KW of solar for $17,250.
They are only really willing to say I will average about 13.8 KWH a
day over a year (5037 KWH a year). I pay 13 cents a KWH so that is
$654.81 a year. That pays back in 26.34 years if it doesn't break or
get blown away by a hurricane.
The federal government will kick back 30% and that drops it to a bit
over 18 years.

The state promised to kick back another 53% but that program ran out
of money and the people who planned on that money are swinging in the
wind right now. With all of the tax payer kickbacks it really made
sense but like all things too good to be true, the deal evaporated.

I was also not really that excited about the grid tie because if the
power is out, all of that generating power on your roof is out too.
The grid tie inverters only work when the grid is present.

That'a a real kick in the ass too, ain't it? * I was quite surprised

The core isssue is safety. If someone isolates and electrical circuit
they need to know it's dead, not being back fed from a PV system..
