OT - new carbon tax 27-Mar-2011 At 10:56:24 AM lacto

Message

I agree with evab that the cost of power increase due to carbon tax will be fairly small , the huge escalations in electricity prices is due to the increase in demand in peak periods and cost together with smart meters to target excess consumption are the battering rams to try and rein in this excessive demand .
Re solar pv . I installed a 5kw system 2 years ago for a nett price of $35,000 and it produces in excess of 7000kwh of which about half is fed back at 66 cents and half consumed at 22cent monday to friday 7 am to 11 pm the rest 9 cents kwh or $3000 pa . It is already depreciated in my books by 70% not a bad return HOWEVER I am about to install anew 5kw on another property which has minimal use and expect to feed back nearly 7000kwh @66 cent or a return of at least $4600 pa for 15 years and the cost of this system is all up $16000 which is depreciable at 10 % pa . Any body who doesnt take up the current offers for solar pv on their own home has rocks in their head . In melbourne you can get 1.5kw for $2400 all up generating 1900 to 2100 kw pa which at 20 cent is $380 to $420 even with no feed back . for every 10 of production fed back add another $90 pa . Most power produce between 10and 4 o'clock so if you work should have high feed back
