In WA the feed in tarif of 47c/kWH (Supposedly fixed for 10 years) is
still available for installations completed by 30th September. I doubt
that there is much chance for anyone still to sign up for this as an
application has to go through Western Power, which can take some time.

I have just got a system installed and expect a payback period of
between 6& 8 years, depending on who you believe as to the future
supply charges.

I would just like some clever person to figure out how I can export
ALL the solar and only use power off the grid, for which I pay around
20c/kWH

If you have a shed etc on the same property - get an extra feed and
meter for it. Feed the solar into that feed, have no other load on it
and take your home power from the existing feed


If you wanted to be extremely bad, you could connect to the neighbours
power, feed it via an isolation transformer and bridge rectifier into
the inverter, and split the difference with them , though this and
other similar methods are very likely to lead to trouble and arent
recommended.

Yes, a separate connection would work technically, unfortunately it
would also incur a standard recurring Supply Charge even though you
may never actually draw power from it.

This + the capital cost of setting up a new connection would certainly
outway any benefit.

If you did try to push back power from some source other than solar, I
imagine Western Power would soon be aware of it, as the maximum size
solar installation is 4kW and I imagine they would have a fair idea as
to what the maximum feed in would be, so if they found they were
paying for substantially more, you could expect a knock on the
door....
Where did you get the 4kw from , if true it would make our installation
physically impossible .


The forms that I had to fill in to apply for the feed in and
permission to install, stated 4kW as a maximum - now that you have
raised a doubt in my mind, it may have been 5kW but I don't think so.

I know that there are bigger installations around but I think they are
under a different feed in tariff.

Are you also in WA?
Qld

and a much larger system , I know of one at 18kw being basically a
power farm

Around Brisbane with at least one major supplier, it depends on how
big the transformer is for that street. In the case of a friend of
mine in Brisbane
his street is strictly limited to 5kw per household. He found this
out after signing up for, paying for and installing a 8kw system after
being told by the power company that this was ok.
(At present 3kw of panels are installed but not connected.)

He is in the process of designing a micro controller based system that
can switch panels in and out of the circuit depending on his own
household power usage, and the sunlight conditions to make sure that
the 5KW feed out limit is maintained for as long as possible during
the day, but not exceeded (in compliance with the Electricity
supplier's 5KW rules).

There are 3 other visible large installations in neighbouring homes
(about 5kw)


This limit may increase in future as the mains and pole transformers
are upgraded.

This would surely have pass certain standards before integration

Probably so, but he owns an electronic manufacturing and designing
business,
has a qualified electrician on staff, so it shouldn't be a drama.
