So tell me how many teraWatts of electricity does Germany use.....then tell me how many £bn's does it cost to generate that amount of electricity and by what fuel.....then tell me how many thousands of tonnes of carbon they have saved by using Solar PV............


Answer is below....

How do solar companies monitor information/performance?
For example, ASG Faq's state;

Will I need to read your meter?
No. You don't have to read anything. Our meter is remotely maintained and sends us information electronically.

What technology do they use?

In 2002, Germany was Europe's largest consumer of electricity; electricity consumption that year totaled 512.9 billion kilowatt-hours.

Electricity - consumption: 2007 547.3 billion kWh


The share of electricity from renewable energy in Germany has increased from 6.3 percent in 2000 to about 16.1 percent in 2009. More than 9 billion euros (US$11.31 billion) was invested in new renewable energy installations in Germany in 2006. Some 214,000 people in Germany were employed in the renewable energy sector in 2006, especially in small and medium sized companies. Over half of these jobs are attributed to the Renewable Energy Sources Act.

The Federal Government aims at raising the share of renewable energies in heat supply to 14 per cent by 2020. By then the share of bio-fuels is targeted to be increased to 20 percent by volume (which corresponds to 17 percent as far as energy utilisation is concerned).
In total, renewable energies have a share of approximately 8.4 per cent in final energy consumption in Germany in 2007 (2006: 7.8 per cent).With this renewable energies helped to save more than 110 million tonnes of carbon dioxide (CO2) last year (2006: approximately 100 million tonnes). Minister Gabriel went on to say: "This means that renewable energies are a key pillar piece in climate protection in Germany."

That's ALL renewables. This is a discussion on PV.
It contributes 0.6%

Germany is one of the world's top photovoltaics (PV) installers, with a solar PV capacity in 2009 of 8,877 megawatts (MW), and 6,200 GWh of electricity generated in 2009. Solar power now meets about 1.1 percent of Germany's electricity demand, a share that some market analysts expect could reach 25 percent by 2050.

Ok 1.1% and rising, 6,200 GWh would certainly do away with a few of our old power stations.

Yes, because of gigantic parks like this:
http://en.wikipedia.org/wiki/File:LiberoseSolarpark.jpg

I mean, just look at the size of it!

"The Lieberose Photovoltaic Park is a 53 megawatt (MW) solar photovoltaic power plant in Lieberose, Brandenburg, Germany. The solar park with 700,000 solar panels which went fully on line in October 2009, is the world's second-largest, and will supply electricity for 15,000 households a year"

Germany have got a LOT of space, plenty of sunshine, and these gigantic installations of massive arrays.
Not a few houses in Dorset with a south facing roof!

Actually, that's misleading. You're now conflating Germany with The Whole World, and PV panels with CSP:
http://www.environmentalleader.com/2009/05/26/solar-energy-can-power-25-of-the-worlds-electricity-needs-by-2050/
Concentrated solar power (CSP), using hundreds of mirrors to concentrate the sun’s rays, could meet up to 7 percent of the world’s power needs by 2030 and 25 percent by 2050, a share that some market analysts expect could reach 25 percent by 2050.

You surely must know you're talking complete rot, don't you?
How much solar power is being generated throughout the whole of the UK at 7pm on a December evening? Heating is on, TV is on, Corrie goes to a break, kettles go on.... and a total of absolutely ZERO watts is being generated by solar. Where do you think that peak surge is going to come from?

Even if every single building in the entire country was covered in solar panels, we would need exactly the same amount of power stations.

Now tell me I'm wrong...

Hi, all PV systems are installed with a total generation meter - this measures to output of the PV only - this is how the FiT is measured as the FiT is actually (in my humble view) poorly named - it should be called a generation tariff, so regular readings of the total generation meter are required - unless in the future Smart Meters are used which can be read remotely.
Hoope that helps

Already happens - on a daily basis I understand.

sounds like when the mobile phone mass projects kicked off back in 2000,

keep your roofs people, solar panels will be dropping in price in the next few years, if not in 5years they will be half the price,

We do have some minimal "pumped storage" in this country.
Installed because we have exactly the same problem with nuclear power - you cannot turn it off so what do you do with the electricity nobody wants, at this sort of time on a summer's morning?

Intelligent metering is also meant to incorporate "freezer storage" in all our homes is it not?
Coming soon "Washing Machine" instant demand and switch off?
