it is not a major alternative to fossil / nuclear / hydro, but that doesn't alter the fact that putting panels on your roof can actually be quite profitable depending on circumstances.
That's very impressive. Is the subsidised deal through which you did this still available? Can you tell us some of the detail of it?It is a great investment. After six months of using power as we need it without trying to save on the cost we are almost $1200 dollars ahead and have free power on top of that. Our panels can generate up to 3.6kw. And that is after the cloudiest, wettest summer in many years.(and tax free too)

After the subsidy, approx what was the cost: therefore how long until the system has paid for itself?
Do the solar panels necessarily need to be mounted on a north facing roof?
(I already have all my north facing roof covered with solar heating for the pool).
You'd be surprised how little difference it really makes having the panels face E or W depending on your roof pitch. In most cases, we're talking about a loss of less than 10% in total annual output assuming it's less than 90 degrees off true north. The exact losses will depend on roof pitch.Do the solar panels necessarily need to be mounted on a north facing roof?

This is the inverter to come with my system.Bottom line? It's profitable to install a 1.5kW system in my opinion. A decent return, tax free, on a fairly conservative investment. Yes it's subsidised, but if someone's giving out money then I may as well have some.
I'm presently running a 1.36 kW system (originally installed as 1.02 kW under the old rebate system) and am giving some thought to expansion toward 3 kW. The deciding factor for that expansion will be financial (bearing in mind that there's not much in the way of subsidies for such an expansion).
With regard to specific equipment, my opinion is to steer well clear of Chinese inverters. Get a German, Japanese, USA or Australian made inverter from a decent manufacturer (personally I prefer the SMA products (made in Germany) since they're pretty much bullet proof in terms of reliability but there are other quality brands as well).
As for the panels themselves - your choice is either generic Chinese or a brand name that is probably made in the same factory or just down the road. Personally, I'd take the risk on cheaper panels but not a cheap inverter.
There is a lot of good stuff on the Whirlpool Forums about solar....

More information;It may not be relevant for tax returns, but it does affect people who are receiving a pension. There is a flyer from Centrelink stating that -
Sounds stupid, I know; but that's the kind of hare-brained idea they come up with.
- If you receive a rebate that exceeds the charge for power drawn from the grid, i.e. if your Power Utility sends you a cheque, you have to declare it as income for the billing period.
- If the credits are less, i.e. if you still have to pay something, there is no impact.
Synergy's (WA) default option is to credit excess credits to the homeoner's account (FAQ 8).On 14 May 2010 the Government announced that feed-in tariffs paid as an electricity account credit will not be assessed as income for pension purposes.
Feed-in tariffs paid as cash to pensioners (for example by cheque or by direct deposit) will continue to be counted as income for pension purposes.
This adjusted policy is also the approach adopted by the Department of Veterans' Affairs.
The adjusted policy applies from 14 May 2010 and applies to all Social Security income support payments (for example pensions such as Age Pension and allowances such as Newstart Allowance).
Each feed-in tariff paid as cash will be included under the income test for 12 months. For example if a pensioner received a cheque from their electricity company for $260 it will be counted as $10 income per fortnight for 26 fortnights.
Payments are made to the holder of the electricity account at the address where the system is installed. Payments are made as credit on the electricity account. If the account is more than $100 in credit arrangements can be made with Synergy or Horizon Power to receive the payment as a cheque.
Synergy will be introducing electronic funds transfer for its customers and this should be available shortly.
Thanks to all who have offered such useful information.
I've just spoken with a rep from Solarlife Pty Ltd who seems less than bright, and suggested I should remove the very efficient solar tubing which covers the north facing roof to heat the pool, to make way for the new solar panels!
I believe Solargain are a National outfit. If they're represented in your area, and assuming their service is consistent across the Nation, I would recommend you at least invite one of their advisors to come and have a look-see and chat.Thanks to all who have offered such useful information.
Smurf, if my aim was to reduce the cost of running the heat pump for the pool (average three month cost in winter around $800) would I need to install a larger than usual system?

Can anyone recommend a firm in SE Qld?
A couple of weeks ago, we added another 6 panels
Yes and No: the Government's subsidy is a fixed amount for the first installation only. We were lucky that we snuck in before the $8,000 were cut back to $6,000 in mid-2009. And luckier still when it came to our power company to charge us for the digital meter: initially, we had been quoted $695 (we needed a 3-phase one), but by the time they got around to billing us, that had come down to $290 as wellPixel,
Does the government REBS rebate apply to extending an existing system?
I put in 3.4 KW of panels a few months ago, but attached them to a 4 KW inverter. I'm regretting now I didn't max out the inverter capacity. If I add more panels to fully utilise the inverter will the REBS discount apply?
Many thanks for your advice above, pixel.RECs can be used to lower the price each time you add more panels; we signed ours over to Solargain - didn't amount to a lot anyway.
The extension cost us about as much as the initial installation, but I had done the sums, and with the increased feed-in tariff, we'll have the entire system paid off in under 8 years. As power charges will only go up, that period is set to shrink even further.
