We just got solar installed and turned on end of July so I'm not sure how much it is saving us as yet. We live in Queensland.

Our bills quarterly were always in the $600+ range.

We spoke to the consultant and he advised us to get a 5kw system with 20 panels. He estimated this system would eliminate approx 80% of our bill.

Because we didn't sign up for the 44c tarrif, we only receive the 8c feed in tarrif and electricity companies also add to it too the amount depends on which company you with. Origin adds 8c, so our feed in tarrif is 16c.

Not sure if it adds or detracts to the value of the house though. We put ten panels on the front of the house that you can see from the street and ten on a side where you can't see. It is a bit ugly but there are lots of houses in our area who have their solar on the front so it's not like we are the odd looking house or anything.

We used solar consultants. Got a quote with true value solar and solar consultants and I found solar consultants more knowledgeable and happy to answer my stupid questions as I knew next to nothing about solar. True value were more expensive as well.

Our 5kw system with 20 panels cost $6340 on the I think it's called jw inverter, just the standard one. Can't tell you how good the system is until we get a first bill though

Sorry I can't remember any of your other questions. The old brain ain't what she used to be
