Qld, SA and ACT are all offering feed-in-tariffs to some degree. If you're in Perth there is a company called Renewable Logic - http://www.renewablelogic.com.au. They are trying to do a bulk purchase of 1 kVa systems, 1500 for $1500. I think all builders should be made to include them on new homes, along with rainwater tanks, we'll be building middle of next year and plan to get both. Re: Photovoltaic Cells Anyone? 11May 01, 2008 1:38 am We have photovoltaic cells and a solar hw service being installed at ML. Delfin had an expensive home management system as part of their encumbrance which wasn't achieving what it was intended to (advances in wireless technology).
Theweek the home management system was removed we put through our house design for approval and swapped for PV power. DH believes it should reduce our power bills by about 20% and we will add more cells over time. Re: Photovoltaic Cells Anyone? 12May 01, 2008 8:40 am I got this from the ANU web site.
They invented Silver cells, and Origin Energy is commercialising them in Adelaide. The ANU publication indicates it takes 1.5 years for the SILVER cell, and 4.1 years for a standard PV cell's embodied energy to be earned back. Quote: The energy payback time of a Sliver and a conventional module is 1.5 and 4.1 years respectively. Frameless panels will have an energy payback time about 0.2 years less than for panels with aluminium frames. For those with a technically mind - more info here. http://solar.anu.edu.au/level_1/pubs/papers/2CV_3_35.pdf Steve Re: Photovoltaic Cells Anyone? 13May 01, 2008 10:21 am I've talked with Origin Energy - Sliver cells won't be available for retail sales for 10 yrs After 4 years - we're in! Re: Photovoltaic Cells Anyone? 14May 01, 2008 11:37 pm Yep, I've been through the plant several times and basically they recognise that they need volume sales, not lots of retails questions (ie how much etc etc for a small value sale) to make their money back.
So they are focusing on large installations, crack the norm, and then go retail. Steve Re: Photovoltaic Cells Anyone? 15May 02, 2008 2:53 pm I'm certainly keen for some sort of solar power system down the track.
You know it's kind of funny, in Qld we could opt to sign up for "green energy" from the power company, which was generated by greener methods, but of course it would have cost us a more! So yes the solar power, being fed back into the grid for a credit is a fine idea, it's certainly in the favor of power companies who can still dictate retail & buyback pricing! So personally my ideal set up is: Solar panels on the roof, going to a bank of batteries (like car batteries) which goes through an inverter (to convert it from 12v to 240v) and then feeds the house. So a big enough bank of batteries should store enough energy for requirements day and night (well in theory) and depending on usage & number of solar panels you could possibly even still have a surplus. Of course some kind of switch would be essential so you could still use grid power if you really needed to. I know of someone who has this kind of set up up in Coffs Harbour. But that's down the track, first thing we're going to do when the house is built is to get the Sparky to do some wiring so at least the fridge can be run by a gen set when the power goes down. Re: Photovoltaic Cells Anyone? 16May 16, 2008 5:29 pm An update from the Rudd budget - only families that earn less than $100,000 will now qualify for the $8000 rebate on home solar installations.
So the 1kW systems that were $5000 will go up to $13000 Apparently in Sydney a few solar installers have had cancellations of 60% of installations because of the price hike. After 4 years - we're in!

Quote: The Solar Homes and Communities Plan ensures that rebates get to the households that need them most through the introduction of a means test, with households with an annual taxable income of less than $100,000 eligible for the rebates. Hence - if you ordered a system but the provider had not applied for the rebate - from 21 May you no longer get it. I cannot see where my post is incorrect. After 4 years - we're in! photo cells 19May 25, 2008 10:15 am Hi all
I am living in Canberra and building early 09 and the feed in tarif rates for the ACT will be 3.88 not a bad little return. The power company and yourself also sign a contract for 20 years to buy the electricity, so a good incentive also to purchase. Recently just moved to the ACT Canberra officially the sunniest city in Australia. Cheers Michael He wants a dream home theatre - she wants a dream kitchen! Re: Photovoltaic Cells Anyone? 20May 25, 2008 8:27 pm paddy - it's great that you get such a good feed in rate!
in NSW energy providers only have to pay the standard price - $1.44 I think (or maybe it's $1.15) After 4 years - we're in! Wish you all the best. Once you signed the contract, they will find millions excuses to charge you.
