Portugal has just acquired a solar power station that operates thanks to thousands of solar panels. it has a total power of more than 46 MW. We our biggest factory (in Narbonne) has a power of 7MW. we would not be one late?

Thousands of solar panels

What is the point of doing "central" when everyone can have PPV at home?

Solar photovoltaics still has significant drawbacks: efficiency, pollution in the manufacturing, difficulty of treatment of used panels (although it is about to be improved, see the link next to the article)
For larger installations, I prefer the concept of solar thermal, which uses less polluting technologies.
As for example at the "plataforma solar" in Almeria (Spain), the largest solar complex in Europe: here a single concentrator on a tower (it is not the only one in the complex):
I like this kind of photos that can visualize how we can focus the power of radiation!
Or at the Kramer junction power plant, USA, with a total power of 150 MW
(here there is no single concentrator but only parabolic mirrors concentrating the rays on tubes in which oil circulates, traversing the whole plant)
I do not know if this technology is more or less greedy in surface and cost than photovoltaic, but in any case the unit yield is better, and the wear is totally different from that of photovoltaic panels.

Certainly.
I suppose heat is used to heat steam-turbine (or stirling) -alternator?
And thank you for the beautiful photos.

Yes that's like a normal thermal power station except that the primary circuit, instead of being heated by a burner or a nuclear reactor, is heated by the sun
Solar + stirling it also exists, for example in Odeillo in France:
(I would put the link to the personal page where the image comes from but I can't isolate it ?! Strange. "Solar + odeillo + stirling" on google ...)
For those who know solar well, it is interesting 9,8 kW for 56m²?
In any case the parable (like the concentrating mirrors) follows the sun during the day, so it reaps the maximum at any time.

Having an idea of what we do better in solar (PV) would be interesting ...
Someone has numbers? power / unit
unit price
average yield ???
Thank you

I went to see the 2004 onsite installation a few days after the commissioning. The midday sun was very high and the mirror almost horizontal.
It is very nice and very impressive technically but on the optical and mechanical no progress since Archimedes and his mirrors (AMHA) against it is surely interesting to show the limits of this type of installation.
The system is particularly noisy, the noise is about the same, as high and unpleasant as that of the old jackhammer compressors. I do not know if we found a solution because it should not be easy to isolate the sensor .

Great photo!!! Bravo Leo!
"Interesting" this noise problem ...
What is at the origin? The solar tracker or the operation of the Stirling?
What is the cold source of striling? A lake? A stream?
Here's a video we made at the EnR fair in Paris last June about the SunMachine Stirling: http://fr.youtube.com/watch?v=IjvP3FJXVYI
It makes a maximum yield of 9.8 / (56 * 1.2) = 14,6% ...
But the good question would be rather: 9.8 kW for X 000 €?
That of SunMachine will cost in 30 000 € ... for ... 1.5 kW ...
I would like to see an annual electrical productivity curve of a solar stirling in comparison to PV panel.
The stirling only produces direct radiation, the PV can use diffuse radiation ...
ps: I like the wooden cabanon behind! It contrasts
