Here's some info - hope you find it useful. Thinking of getting some more
panels to try and get up to 5kw if I can get organised enough.

Anyone is willing to share experience, good and bad,
I will probably be installing a small system which will most likely
meet most of my needs.
I got my panels installed around 3/9/2010
It was a lot of paper work, you need to get them inspected and not
meant to switch them on till
then which takes weeks, you need a new meter and you need to be home
for many of these events.
You also have to
fill in the forms from your power supply company to apply for rebates
and special rates - but well worth it.
We have a rate based on time of day 30c 7am-11pm week days and 11c
("offpeak") otherwise so check your
electricity bills to compute whether it's worth while.
For us it was well worth it because we got a 66c /kwh buy back, so
when at work and they generate an excess
of power the company pays us 66c/kwh. We haven't paid an electricity
bill since (we got 3kw system).
Origin billing is a night mare because it takes ages on the phone to
get through to a human, you have
to talk to a special solar power section, they stuff up the billing
quite a few times. No reading, sending
the wrong billing (not paying the credit - took three calls to get it
straightened out). But all said and done
they did what they said, eventually...
Here's some questions I answered to another query - just cut and
pasted it below:
how much roof area does it cover?
We have a north facing roof (the best facing) which gives apparently
97% or so efficiency. Of that we have used about half (we have a
reasonably large roof). The electricity company only lets you supply
up to 5KW (other wise you have to become a different type of contract)
so we should be able to expand up to that if we wanted to.
how many panels she has and/or what is the output in
16 from memory - 3KWh
how much did it cost to install
roughly including installation and related equipment such
as the 3KW inverter
You really have to look at your last electricity bill to see how many
KWh (kilo-watt hours)
you use per day. On a sunny day, in the middle of the day a 3KWh will
generate at least 3KWs
in winter perhaps a little less and much less if cloudy.
We seem to get between 6 and 12-14KWh per day from our system. We
use an average of 14KWh per day so we are hoping to be nearly neutral
We got it through Bunnings but here's the consultant who did the
work and I was very happy with.
The major problem with it was cracked roof tiles - they cracked 1-2 on
setting up the system and
we had another might have cracked later during a windy day. But that
was a hair line crack which you
couldn't see and only noticed water coming through on very heavy rain
- which made it hard to identify.
The consultant didn't want to come back until we could find the
cracked tile (busy man et cetera) which I finally
did during one rainy day (took photos on the phone and e-mailed it to
him). He then came back and replaced
the crack tile (we have a pile of spares) and checked everything else.
No problems since.
Here's the details of the consultant - have no troubles recommending him.
