Ten years ago I was living in Arnhem Land and realised that one day I would have to get back into the real world. I bought a house in Cairns (investment with a view to occupy when I moved). I wanted to move to Cairns after a while and eventually retire. Thinking about this I wanted to retire with as few bills coming in as possible. I was renting the house out at the time that I decided to install a 6 kw system. $12000 at the time. Put it in my name and the people who rented the house got free power for several years. 44 cents rebate per kw . I got in 2 weeks before the deadline. Paid for itself in 7 years after rebates and tax incentives. Now I break about even as electricity price hikes are continuing and I also run a swimming pool pump all year. Solar is continuing just to get cheaper as well as batteries. I am locked in at 44 cents until 2028. If I was to add a battery bank I would lose my subsidy. All my neighbours have solar, with some having 10kw systems, but 5 kw is most that can be fed into grid for a tariff. Solar has certainly been a bonus for me.
And it's good for some......if you can afford the initial cost.
But, one factor with solar panels is quality and use by date. It took you 7 yrs to break even, but how many more yrs before you have to replace the panels ?
I like the idea of being completely self sufficient, but the cost is still too far out there to be able to easily run a pool pump, pool solar pump, aircon etc.
I left it too late for installing solar (bugger all rebate now ) and can't afford it now either, and at 60yrs old, not sure how many more yrs I have left at the present address, so solar is the last thing on my mind.
Electricity took 40 yrs to become widespread and reliable and so renewables may do the same, and may change in system designs and type of renewables, but in the meantime, reliable (and especially baseload ) energy means COAL. For how much longer
Who knows, but my guess is at least 10 plus years.
