    Default solar power and hot water

    ok as the title suggests , we currently have solar hot water , however we will be moving soon and may not have it .
    question is does anyone have experience with the different things available and ititial set up costs to period that we will see savings (I also understand that power prices will soon be skyrocketing)
    ok solar hot water
    do you go solar hotwater
    evacutated tube solar hot water
    or heat pump ,
    all these are covered by the govt rebate

    also for solar panels to cut down costs
    how is the pricing for these things and what sort of benefits . I figure we could almost be independant on a 3kw system as currently we spend approx $350/quarter ?

    anyway , first hand experience ? links , prices etc ?

    Only $350? Last bill here was over $500 and some friends have had back to back $800 bills.

    I would say heat pump for hot water. I have heard of a few problems with solar and cold mornings. Might not be a huge problem for you north of the border.

    A grid connect 3kw system based on the website of a dealer here in Newcastle is listed as $19,000, cost price before rebates. That is made up of 18 x 170w panels so roof area may not allow for a system that size.

    I'd steer away from a grid connected system if financially possible. You have no power storage , mains power goes off , your power goes off as well.

    But it depends on your reason for going solar. Mine would be to totally disassociate myself from the power companies and have self sufficiency. I would have no desire to have to sell power to them for X amount only to have them sell it at a massive profit to others.

    Grid systems dont allow you to have batteries. What you create during the day you use , any extra goes in to the grid. You are buying back off them at night, unless you have created enough extra.

    Power prices are a joke though , but in all honesty if I was only paying $350 a quarter I wouldnt bother going solar.

    i will change the hot water system , but I was just thinking about the solar electricity . with the rebates and 10 grand interest free loan it seems like an ok thing to do .
    am also thinking about switching to gas for cooking . Atthis place we have induction which also uses a lot less power , but gas would be easy and conveniant for when there is a power outage

    Its a shame you arent supposed to use wind power in residential areas. I mean how much noise could a small unit make?

    Someone really needs to figure out how to generate using a wind setup attached to the whirlybird roof vents. They usually turn even when there is no wind.

    Off to the shed of invention i go!

    I have heat pump hot water and it was the best thing I have ever had installed. I have 250lt unit which is 90lts more that the old electric one.

    It will still heat the water @ -10 degrees temp. It only uses electricity for the compressor, fan & electronics. It has no element and at the moment I am saving a $1.10/day on my electricity.

    All up cost to me after rebates was $1,700.00. This included relocating the unit outside and the electrician to do the wiring.

    It depends what inverter you choose...

    It's australian made and designed...!

    With the SP pro you can achieve it all.

    Please note that you now get in Victoria 66cents per Kw for power you upload and pay 26c for download.

    It's a win-win at the moment, especially Victoria.

    See above re-batteries...


    Please also note that at night ALL your power is at 9c a Kw...so all the power you use is as if it were connnected to your hot water discounted rate.

    A very fair arrangement at the moment.

    With the generous feed in tarriffs you can make money out of legislated feed in tarriffs...an excellent way to screw your power company...

    But it all starts at 3kw...don't bother with 1 kw systems

    I also see you can have these installed and retrofit the current hot water tank which would cost even less .

    This thread covers quite a lot that has already been discussed on this topic.




    BF2010 , most of what is needed to run the above setup is not covered by any subsidy , it's classed as a luxury , Even if it were covered 10K would only give you a deposit on something like this.
    Well worth looking into if being independent of your power company motivates you .

    BTW there are quite a few very informative threads already regarding Solar Hot Water if this is your main focus.

    You sure you dont want to post the link again BF ? Just in case anyone missed who you work for.

    Thats all good and fine if dont plan on claiming a government subsidy. I am yet to see anyone " making money " other than a few dollars. But I would suggest reading some of the previous threads as there has been a number of recent discussions on the topic.

    Well excuse me .

    I saw an opportunity to enlighten you guys with a link to some of the latest technology, instead of being misinformed.

    No, I don't work for the manufacturer.

    Maybe if you guys were a bit friendlier you might learn something.

    Beware of state and local planning laws if installing gas, as found out that in our area if you have a gas conncection, and your electric hot water service dies, the plumber has to replace with a new gas unit! Unsure how this works with solar hot water services, although have seen these with gas backup!

    We delibrately got our plumber to install a larger capacity copper piping to run cooking for now with ability to expand heating and HWS down the track, with no bottlenecks in supply! As for cooking, notice the difference burnt a few pots dry in the beginning as its so much more efficient!
