Australia going solar: gonna cost ya mate. : Comments

By John Daly, published 8/12/2011

Even if solar power gives Canberra sticker shock, it seems preferable to make local arrangements for more environmentally friendly fuels such as natural gas.

You have to be unlucky to break a glass , it is toughened glass. If a brick happens to fall out of the sky and breaks the glass, they say to lay another one on top leave the broken bits there. Hail does not rate at all.

Individual,

If you google search the type of panels that I have you will notice that they are not glass, they are thin metal panels so hail will not break them although a big enough hail storm may have some impact if severe enough.

579, its not particulate matter the greenies are on about, its carbon dioxide emissions. Tastless, odourless, harmless gas (except if you step into a room full of it with no oxygen). Given the amount of it coursing around your body and out your lungs at any given point in time, I think its safe to say its not cancerous!

The idiot greenies have just renamed it "carbon", because few mugs would get worried about global warming if they called it by its normal name. Yep, they've now found a way to tax the air we breathe. Labor should be proud.

Carbon emissions is what is being taxed. The carbon particles are causing a green house effect. Carbon is from burning fossil fuel. It is black, and measurable particles. C02 and carbon are created at the same time, from burning air with the fossil fuel. Every thing needs air to burn. Put your hand over the exhaust of your car and you will get a black stain, that is carbon.

Carbon has been found to be carsnogene in animals. Human tests were inconclusive.

@Martin N: At $2/W (low commercial price today)

Your information is a little out of date. Prices FOB China are $1/W, in quantities for a 30KW system, as in that is what was paid a few weeks ago, shipped to Brisbane. Prices have dropped by 20% in the last 6 months, and by 75% in the last 2 years.

So assuming you are right and it is 30KW per person per day, and assuming an average of 4 peak hours per day, that is $1 per 4WHr / day, or $7,500K per person to supply the entire electricity needs of Australia. And those panels will last at least 30 years. I'd be amazed if that price hasn't dropped to below $1,000 per person by 2020. That for all intents and purposes is close enough to free.

There are lots of other costs of course, and the storage problem is still with us. But nonetheless, when you are looking at paying $7/W for nuclear generation capacity, versus $0.10/W for PV Solar and $0 fuel and disposal costs, that leaves a lot of money lying on the table to solve those problems.

To put it in perspective, 240TWhr at a retail price of $0.20/KWhr is $48 Billion/yr. $48 Billion can build a lot of pumped storage, DC transmission lines, smart meters, and car batteries.

I wasn't a huge fan of these solar subsidies. But world wide the effect of them has been nothing short of remarkable. They have lead to the price of PV solar halving multiple times during the last 10 years, and this trend looks set to continue.
