Solar panel system for domestic use.

[SonOf]

Need to also take into account that currently there are moves my some distribution companies to try and make people who have solar pay a higher network cost.
Their argument is that people with grid connect solar are making prices higher for everyone else so need to pay mo I am not going to get into this here, suffice to say I work in the industry and their argument is rather flawede.

Westy is right though, check what the FIT is in their area and also what their usage is now via their last couple of bills. This should help calculate what system will be best.

Anything under 20c per kwh will mean they will most likely pay a bill still but it will be very small.

I'd love to have a battery bank and be off the grid like my wife's uncle no power or water bills for him .

over here they still send you a bill if the power and water are available at your house, bloody greedy govt bodies.

Yea I thought they would but could only be at a minimal cost surely

My in laws reckon the unit and panels will produce 12/13 kWh and they use on average 8/9 kWh.
I think they have been quoted $4990 for a 3kW inverter with 12 x 250 watt panels.

Also depends on your long term intentions for the house and if you will stay or move on in the future.
I would be interested to know how much value a system would add to the value of your property.

Probably nothing more than a selling point.

If you have anything conected to they charge you.
You need to be physically disconnected from the grids..

There is a formula where you can work out what size you need. Can't find it or remember it though. We have a 2kw system and we needed a minimum of 3.63kw to totally cover our bills. If I were to do it again, I would go no smaller than 5kw I reckon. On a $350 bill there ends up being around $200-$250 to pay so its helping.

Not here you don't, if it runs past the property you get charged!
