10 MW is not a lot of power. especially when it will be genreated only around noon on sunny days. peak demand, when it is needed, is befor 8am and after 5pm, times when this plant will be generating close to mothing.
Fail.
The only people to benefit from this will be the contractors skimming off the gov. if this thing ever gets off the ground, expect it to cost 2-3 times the 60 million estimate.
I live a few hundred miles north of Chicago, and we had almost solid two weeks of overcast sky this winter, and more cloudy days then sunny. I doubt that solar array will ever pay for itself. The electrical grid is not always wanting more energy, the demands ebb and flow, so during the day time hours if there is no demand for energy, and you are producing it anyway, you may actually have to PAY fines.
You cannot always expect to sell the energy you produce, just because you tied your solar panels into the electrical grid. Power plants have to throttle up/down energy output all the time, so they can react to the energy demands of the market.
You are correct, the peak times for energy are early in the morning, and later in the evening, not at high noon. Solar arrays produce DC power, which has to be inverted to create AC power, so they are fine for local use, to help power an office during working hours, or charging batteries.

Fail...
Fail... yeah love for oil, that is.
IMO, every drop in the bucket counts. German realized that a decade ago, and now have 14% of their energy requirements met via alternate sources. And guess what... Chicago gets a lot more sun than the Germans see.

spectacular increase in solar plant deployment has accentuated the 2008 rate
deficit. However, it will do so even more intensely in 2009, at which point every plant
]that became operational in 2008 will by then have an entire year online, and also
because many of them, operating under RD 661, will begin billing in 2009 (around 1222
MW, inferring from CNE estimates). For 2008, the mean sale price of electricity
generated from solar photovoltaic power is 7 times higher than the mean price of the
pool.
Thus, the over-cost of photovoltaic production, which has to be somehow subsidized
affecting the rate deficit, is and will continue to be enormous. The accumulated rate deficit from 2000 to 2008 is around 15,189 million Euros (based on provisional]
settlements published by CNE). Just in 2008, it has amounted to 5,640 million Euros (over a third of the total deficit). The estimated 500% growth in installed capacity in
2008 implies that the rate deficit could increase uncontrollably in coming years.
. The looming collapse of the photovoltaic sector
It is in this context that the Royal Decree 1578/2008 of September 26, 2008 (whose
[left]results we will not be able to analyze for a few more months) becomes effective and sets forth a very restrictive and arduous regulation on the photovoltaic industry. First of all, it will very much favor roof installations (on buildings) to the detriment of those on the ground because the recent “speculative” growth of photovoltaic has taken place in the latter form; fears of an increasing rate deficit has reined in a massive deployment of solar plants by producers foreign to the industry (according to the Ministry of Industry). Secondly, it greatly decreases retributions to new installations, applying a reduction close to 30%, which especially affects the ground photovoltaic industry
Your vaunted Germans and the rest of the EU are learning the value of thier renewable programs.......
And that is a good thing. Being pragmatic that they are, acknowledging the shortcomings, they are bound to address it. Even we can learn from their mistakes. Thats the good thing about being able to think rather than be a sheeple. Avoid extremism at all cost, don't put all eggs in one basket (and more so on a basket made of stuff that has very defined lifespan).
Now look at the vaunted oil crazies at home. When will THEY learn?

Not true. In the summer the demand for electricity basically follows the sun. It increases until the sun goes down.

The net metering tariffs I know of don't have time differentiated rates in them. That would be a better deal from the panel owner.

You couldn't be more wrong. The vast majority of utilities in this country peak in the summer and the peak is due to air conditioning load. Think it through next time. When does that ac unit run the most?
