Have heard talk that all electric hot water systems are being phased out in qld only have a choice of solar or gas I think Link to comment Share on other sites More sharing options...

Posted 05/10/10 08:52 AM Share Posted 05/10/10 08:52 AM ooking into getting like a 2kWh solar power package at a new house.anyone got a similar setup? Trying to work out how much I will be earning in profits. I average 1000kWhs a month according to my 12 month bill and its about 120$ a month atm. Ive been doing some reading on these solar system setups.Can I just confirm, lets use truenergy as an example, according to:http://www.truenergy.com.au/solar-power/faqs.xhtmlIf I fit a 1.5kW system for 3700 – 1300$ rebate, and currently according to my bill, over past 12 months I average 900kWhs usage, at about $120$ a month.With a 1.5kW system, how much do I make back with the .60 cent back to the grid + the 6cent truenergy insentive ontop? Is there a calculation on how much I will make/profit for each month with the above on average?from my understanding.I won't be pumping in .5kw all the time. my inverter might only trickle the excess power back into the grid or dump it as waste to avoid over charging.What if I get / apply for a bigger inverter? What if I get a 2nd inverter or 5th? Can I feed more back to the grid once they are all fully charged? eg, one can run the power in the house, whilst the other 4 are feeding x kHw back to the grid @ .60c+ ?Also, how does it work with taxes? Is it like a 2nd job/source oif income? Link to comment Share on other sites More sharing options...

If the grid power is out, then you have no electricity, even if your solar system is actually generating it.The other thing is you get nothing paid back until there is a full 12 month trend on your net usage. So for the first year you just get to look at a credit on your bill and you don't get a cent. Link to comment Share on other sites More sharing options...

Lifetime Members 7,935 Member For: 20y 9m 14d Gender: Male Location: Sydney Posted 05/10/10 09:58 AM Share Posted 05/10/10 09:58 AM I have done some checking and have a mate who spent about $18,000 on a system.Most systems will not let you use power for the house, you just feed it into the grid for 60c per kw/h, and it costs about 32c to buy it back, so in theory you make money, as most houses use less than you generate.What none of the glossy brochures tell you is the money you make (all of it) is subject to income tax, so you can go backwards, as you get taxed on the entire credit form the power company, yet still have to pay for the consuption. Unless you are going to be entirely "off-grid" it is not a worthwhile prospect. If you design your house to be primarily 12v, it can make a huge difference.

Guest XR09 Guests Posted 05/10/10 10:23 AM Share Posted 05/10/10 10:23 AM And the panels deteriorate quickly. As in after a year or two they give back less and less juice. We spent a fortune on it to heat the pool and cut costs. I don't even think it recouped the cost of having the pump circulate it all the way back up to the roof. Let alone the initial set up costs. Now it just sits up there looking ugly as shoite and never gets turned on. Think how much compounded interest you would get off the money if you just threw the cash into a fixed deposit. Or buying shares in the company that makes them.Another great Labor initiative. What is it with Labor and house roofs. Link to comment Share on other sites More sharing options...
