Shame that since with the rebate, I would almost certainly go down this route, without it, I'll just sit and watch things develop. I am sure I am not alone in this. 3xb Thing is if you look at the data, 2 Suncubes (ie: $3000 worth) can do the same job at $10,000 worth of flat panels! Even if you took a $4000 rebate off the flat panels ($6000), you are still better off with Suncubes. By a long way.. And that is just with 2 Suncubes. If you work out that you needs say 10 Suncubes (that's a lot of power), imagine what that is going to cost in flat panels!! Not only that, but how much space would the flat panels take up? A $4000 rebate is not a deal breaker. Re: solar powered house?????? 18Mar 27, 2007 5:08 pm Greg Watson of Suncube just posted a link on the Yahoo user group to an image on his site that shows estimated power output from a single Suncube, depending where you are in Australia.
http://www.greenandgoldenergy.com.au/im ... tralia.JPG This thing is gonna be awesome. $1500 for a Suncube with a built in inverter $1200 for a Sunbube (DC) without an inverter Bring em on! Re: solar powered house?????? 19Mar 28, 2007 11:40 pm Hi all,
Am a little confused about the power output of the suncube, had a look at their site and found this in the 1500 buck inverter one Output 240 Vac, 1 Amp, 50 Hz using an in-built AS4777 approved grid connect inverter. 240v @ 1amp = 240w@240v a standard 120w 12v panel will put out 10 amps ( 120w divided by 12 volts=10 amps) 10 amps x 240volts +2400 watts (less the usual 10-20% loss) maybe my math is wrong but these things dont seem to put out that much power Re: solar powered house?????? 20Mar 29, 2007 12:50 pm crunk81us,
Yes, a problem in your maths. Suncube = 240 W Standard panel = simultaneously 120 W (correct) and 2400 W (incorrect) So basically the Suncube puts out twice the peak power. The real beauty however is that since the Suncube tracks the sun, it's output remains fairly high day long. The flat panel quickly reduces power output as the sun moves from being perpendicular to the panels. So the Suncube, for the same amount of money, has a higher peak power output and keeps closer to the peak output power as the sun moves across the sky. Cheers, Casa I looked into it a few years ago and my conclusion was to just build a carport that will support panels and get a system installed separately. The company I looked at had… 1 6481 You’re on the right track, wire brush in a grinder then a zinc rich epoxy primer then a top coat of some sort, like a waterproofing membrane. Raising the concrete would… 1 7031 How good is Simeon?! Always taking time to help others out! Wish we were building in NSW and could work together. Thanks for all that you do! 7 6567 |
