I am happy to help where I can, seems like what I am saying falls on deaf ears.Hi Frank,
Firstly I'd like to thank you for your input into this discussion, it has made me do a fair bit of research on the company and the numbers involved.
I think they do that now for a lot of people now. My off-peak power is ~10c/kwh our peak is ~23c/kwh (both numbers have the same discount of 7%)
Peak is 7-11 Monday- Friday, Off-peak the rest of the week, and weekends. There are 80 hours of peak and 88 hours of off-peak per week.
Now my point, that I think you misunderstood, is that this difference between peak and off-peak rates is what favors solar, with the assumption that the tariff you pay is reduced by the amount of electricity you produce and consume, and that the residual power fed back into the grid is paid at the same tariffs, in my case 10c for off-peak and 23c for peak.
It becomes quite simple to do the numbers. For Monday to Friday all the power generated by solar panels is at the peak rate price, while on the weekend the solar is produced at the off-peak rate. That means that 5/7 or 71% of all solar generation is at the peak rate.
For the BlueGen unit that operates 24 hours a day, it produces electricity at the peak rates for 80 out of 168 hours in a week, or 47%.
If the solar panel set-up was to match the BlueGen unit in output, say a 10kw system where there is an average of 4.8 hours of useable sunlight per day, then the return for the production of power will always be higher for solar while peak prices are higher than off-peak prices. If peak prices are raised relative to off-peak, then the numbers favor solar even more. In fact the one thing that BlueGen needs is for the price of off-peak to be the same as peak, to take away the advantage of peak pricing when the sun shines.
Added to the above is that solar produces no GHG, has no yearly ongoing cost and that the BlueGen has an input cost of ~$1545 per year for gas.
Can you explain this a bit more?? I know of many people who are very happy with their solar set-up and the reductions in their bills.
All they have to do is their sums and go with a retailer that will allow existing discounts to continue, mine does.
Another aspect that has been overlooked in the debate about the BlueGen units is in terms of infrastructure, not the electricity infrastructure that the company talks about, but the natural gas infrastructure. If the plan was for 10s of thousands of these things to be spread around the suburbs, can the existing gas pipes etc handle the extra load??
Today's action in CFU shares was very high volume for not much upward movement. There seems to be plenty of sellers at these slightly higher prices.

I give up you are right, solar has the edge, but this doesnt matter.
It doesnt matter because no one will spend 50k to buy 100m2 of panels,
and they dont have 100m2 north facing, the 1.5-2kw systems that are on there now barely fit.
It doesnt matter because we are talking about CFU not solar, no body is going to pay 50k for a ceramic fuel cell system which would fit neatly where the dishwasher used to be.
So what is the Government going to do about it?
That is the real point.
Why are we talking about solar or fuel cells or windfarm or geothermal etc..., at all, none of these things would/can exist without the government getting
them up.
I would like to know what the government is going to do about CFU, because thats what matters to CFU, nothing else comes close.
In Europe governments have given the 'bluegen' fell cell concept the thumbs up, it will be part of the mix.
Brumbys words tell me Victoria is next, http://tinyurl.com/29r733v
he is also telling us all solar has moved on out of the suburbs and going large scale.
The government has a job to do cut, co2, the average bloke on the street with 50k burning a hole in his pocket, calculator in hand, is not going to do it.
The gas pipes can deal with the extra load 302mj's per day, per unit, I use 380 myself now to run my heater, so if you can build 10 000 new homes, you can keep the gas pressure up to a few bluegens. Summer, autumn, spring, wont be any problem, less heating.
