A complementary source of energy only, sorry folks...
In the summer, Finland usually receives more radiation energy from the sun than Central Europe, but in the winter the case is the opposite.In the south of Finland, the annual amount of the radiation is almost as high as in Central Europe. A solar heating system can 'ONLY' cover 10-30 per cent of the heating energy requirement of a single-family, the initial out-lay aside, how many Australians can afford to install $80,000 solar panels on their rooftops, what on average does an Australian spend on power in their lifetime?
It's complimentary, nothing more, thus cant be depended on as a primary source of power.
Solar thermal energy (STE)[ is a technology for harnessing solar energy for thermal energy (heat). Solar thermal collectors are classified by the USA Energy Information Administration as low-, medium-, or high-temperature collectors. Low temperature collectors are flat plates generally used to heat swimming pools. Medium-temperature collectors are also usually flat plates but are used for heating water or air for residential and commercial use. High temperature collectors concentrate sunlight using mirrors or lenses and are generally used for electric power production. STE is different from photovoltaics, which convert solar energy directly into electricity. While only 600 megawatts of solar thermal power is up and running worldwide in October 2009 according to Dr David Mills of Ausra, another 400 megawatts is under construction and there are 14,000 megawatts of the more serious concentrating solar thermal (CST) projects being developed.

Also, wouldn't it be ironic if solar panels contributed to reversible atmospheric warming, and caused the earth to retain heat?
What is the life expectancy of solar panels...about 20 years apparently.
Put your hand up if you would use $80,000 worth of power in 20 years.
Lets see... the average power bill for an Australian family of 4 is what p/a?
8 Jan 2010 ... That's $989 per year allegedly.
Well....
In the past 12 months we have made changes to the house and our energy use and have gone from an annual electricity bill of approx $2400 per year to what I expect will now be near $1500 per year. We have always had the hot water booster(now solar), pool, AC and bore pump all on Tariff33 which makes a difference. Now our total energy use for the year over both Tariff11 and Tariff33 is 9000kWh. This equates to going from an average of approx 43kWh/day down to 24.5kWh per day.

So... is this not roughly about $20,000 (coal power over 20 years based on a family of 4) -vrs- $80,000 every 20 years, for an average size family converting to solar, and even then, it's only supplementary this and you will be paying for a family of 4 for a semi-reliable complimentary source of power?
Long after the kids have left home and are paying their own power bills, we'll still be paying $80,000 for a complete solar conversion every 20 years.
Compared to much less when compared to coal driven energy.
Do the maths ...
Lest we forget the silicon waste...
So it;s not only our celebrities silicon tits we have to worry about.....
