    Just thinking if it is worth having a system maybe you blokes that have one could give me your thoughts 
    are feed in tariffs OK ?
    has your bill dropped?
    do you get a good daily power supply?
    how much power do you export back to the grid?
    did you need to change your meter?
    Has it paid for itself?
    thanks in advance for your reply

    Put small  system (4 panels) on 4 years ago i think,  for $ 3.5 k was only getting $ 100 off my bill i went thru 3 inverters , 1 from lightning strike on power pole in the street one failed after a week. Small print says turn them off during electrical storm.
    Lost money on that idea, we  just sold house and was a good selling point i guess.
    Do your sums on how long its going to take to get your money back,.

    This is a very interesting topic that should be explored more. 
    Years ago I organised Solar on the Castle roof with then wife, and it was like the max of 86 or 88 cents per. Good bloody value then. Think is a little lower than that now. 
    Going, to install solar soon on top of my current shoe box, but after more "current" information.
    Bloody hell, next gen be ridding "lectric M.C"s and be plugging into solar system when getting home, for electric ride the next day.

    How can ya tell a shonky solar installer/business from a decent one? Word of mouth ... and hoping the bloke you contract to doesn’t turn up at install in a clapped out old Ford with non-English speaking mates who came by the kit off the back of a truck, therefore warranty discussion is a non-discussion?

    I put a 2kw system up a few years ago, feed in is only 7.5 cent's (missed out on the high feed in ) and cost from grid about 19 cent's so I  get less than half. Convert all lights to led to cut costs, if you can pay up front with no finance and forget about how long to recover the cost and just concentrate on the savings off each bill it works. Inverters make the difference more than anything, cheap shit ones can cost power and be dangerous with larger systems feeding high DC voltage to them so watch packages offered by some companies and do research on inverters be prepared to pay a bit more for a better one for safety and efficiency. Battery storage will give back more but cost more as well and battery life could be an issue creating on going cost for replacement, how many rechargeable things have you had that only last a year before the batteries die and make it useless unless you replace them so with storage systems costing so much, having to replace every 5 or so years would mean you would never be able to recover the cost. Because of the shape of my roof not all the panels face north so later in the day some fall into shadow and are less efficient and this can effectively shut down the whole bank meaning no power from half the system for part of the day. I have an inverter on each panel feeding ac voltage into the system so if one is in shade the other 7 still work independently, down side is difficulty in installing storage.
    In the A.C.T you have to replace the meter with a digital ont that measures each tariff separately plus feed in amount. With a couple of rebates we get and using reverse cycle heating for winter it only cost $260 for winter compared to almost double for gas heating,  do your own research on panels and inverters and know what brands they offer on package deals as quality can vary. 
    Sorry for long winded reply.

    I had a 3Kw system with a 4Kw inverter installed in 2004, $18,000.
    all facing north, we were paying $800 a quarter, now we range between $100cr to $200 bill, depending on estimate or actual read
    we get $0.55 tariff

    we have had 1 inverter replaced a year in, near 12 month threatening the installer, contacting ombudsman, till finally, contact the manufacture, they sent a new one and paid the electrician to install it

    I know a couple guys that have 10Kw systems on their homes, they are on good money

    some great info here fella`s it touches on all the concerns I have had . I am in NSW & gone with a mob called Space Solar their installers are employee`s of the company not sub contractors . I have chosen a 3kw system  for my shoe Box with Canadian panels & a Sun grow inverter made in japan but has a good record here in Oz European ones are another couple hundred bucks . I have a flat roof so will need a tilt up frame & have  a good unrestricted North facing direction. Ferrett62 not long winded mate I think your taking about Micro inverters that go on each panel converting to AC before it goes into inverter I asked about them but would have put another $1800 on the price will have to hurry up & wait till new year for install so will have a chat with my Retailer see what they are offering .your right about the batteries Cropduster they are advancing but not an option at this point Thanks a heap for all ya replies

    We have the biggest system Ergon will approve which is 6kw from memory. Thats 24 panels on the roof. It took them ages for Ergon to hook up the meter and theres a possibility the panels were switched on and wound the meter back. Since the new digital meter went in, we've used a shit load more than has been put back into the grid. There's a possibility that could be because the how water system is on the way out but we were gone for 3 days last week and came home to 150kwh used and 40 produced. That seems a bit strange to me. 
    That system cost about $8,000 from memory and we're waiting for Tesla to get their act together to put a battery in which is an additional $12,000. 
    I'm thinking we might have to look into how we have it set up at the moment. I think that since we're now using a lot more electricity, it might be better to have the hot water taken off solar and put back on Tarif 33. 
    We also looked into going off the grid but apparently Ergon won't approve that unless you're building a house out in the sticks away from existing power lines.

    I remember the day we got the solor on, the old meter was spinning backwards, got some good credits, we went over seas for 6 weeks and came home to a great bill

    we thought this solor is shit hot, then the new meter was installed, still get the odd credits but nothing like before

     That sounds like there is a problem, my 2kw system on a sunny day will produce 13-15kw a day. Not great but half my panels face east so the system only works at capacity from mid morning to early afternoon when all panels are in direct sunlight and that is when sunny not cloudy or raining when I get as low as 4-5kw. Your usage over 3 days sounds high 150kwh ×10=month ×3=3 month billing period =4500 kwh per bill and at what I  pay per kwh would be $855, these are rough figures but sounds high. Instead of battery you could go for a solar hot water ( most states offer rebates for install) which would give you heating panels on the roof and a new h/w system. I don't know if the meter switches between solar and grid, meaning during the day you would still be paying for power just offset by what you are feeding in. My last bill showed 1100kwh for 3 months which includes winter, I have all led lighting in my house and an inverter refrigerator with gas h/water (gas for cooking & h/water only) I now longer use gas heater just reverse cycle air con. I don't know how much difference all this makes in the end, I am just a cheap cunt who hates paying bills.

     Looking at this very interesting subject, again, I think I did not receive in the 80 cent bracket, but was in 60 cent bracket for sure. Which was great, but now must start all over again.

    After homework has been done and discussed with people, who know. 

    Do Not get "Dodgey Brothers" to install system.
