Talk:Solar Energy Generating Systems

percentage of electrical output not coinciding with reported values
The non-cited claim in this article that 90% of electrical output comes from sunlight does not jive with reports I've seen that 25% of the SEGS plants have been allowed to derive from fossil fuels.

The following is from the U.S. DOE's EERE website; https://www1.eere.energy.gov/ba/pba/pdfs/solar_trough.pdf

"Note, even though only 25% of the annual energy input to the plant comes from natural gas, since this energy is converted only at the highest turbine cycle efficiency, 34% of the annual electric output from the plant comes from gas energy. "

If someone has some reliable reference that indicates something far different than this cited percentage, I would be grateful to know where that is.

Images
Why are images that tell part of the story not allowed? This is really silly. Jcwf (talk) 21:27, 19 October 2008 (UTC)


 * The objection seems to be to images without accompanying text. To reinstate the images, you might write a short section which describes the sub-topic which the image conveys.  If there is no clear corresponding sub-topic, then this indicates that the image may indeed be redundant. Colonel Warden (talk) 08:35, 26 October 2008 (UTC)

What is field area?
Why is it so big compared to the area of the site? —Preceding unsigned comment added by 87.237.64.150 (talk) 14:00, 19 February 2010 (UTC)


 * It isn't. Check the unit - one is listed in square meters and the other in square kilometers. Rmhermen (talk) 02:14, 14 March 2010 (UTC)

Still there is something weird though, if you add up the areas on the table they add up to something lik 2km^2 while it says 6.5km^2 in introduction. Maybe one is just mirror area and the other land area? —Preceding unsigned comment added by 78.175.32.254 (talk) 16:17, 2 January 2011 (UTC)

Agreed - this article is quite deficient in defining its terminology ("site" vs "field" vs collecting area, "name plate capacity" is at 1kW/m2 on mirror area? "capacity factor" is determined precisely from what?). The normal-incidence aperture dimensions of the mirrors would also allow one to obtain an idea of what the performance is, but one simply can't do it with this little defined. I edited article to include the following: The term "field area" is assessed as the actual collector area. Wikibearwithme (talk) 19:25, 18 February 2018 (UTC)

Ownership
Information found here says that the SEGS are owned by three separate bodies as: It also says that No.2 is collectively called SEGS 3 through 7, and that it is owned by the Kramer Junction Company. Could someone add this information to the article? I'll add if it hasn't been in a while. Thanks. Rehman(+) 12:41, 31 March 2010 (UTC)
 * 1) SEGS I & II
 * 2) SEGS III, IV, V, VI, VII
 * 3) SEGS VIII & IX

SEGS 3 Through 9 is now owned by Florida Power And Light and operate under Nextera Energy Resources. — Preceding unsigned comment added by 98.112.24.99 (talk) 20:21, 7 July 2011 (UTC)

Coordinates
Could someone add separate coordinates for each of the nine units in the table? I've tried but came up with no luck in finding the information. Rehman(+) 12:41, 31 March 2010 (UTC)

What Did They Cost?
It would be very intersting to find out what these plants cost, for people interested in the economics of solar energy. I'll see if I can find any information. DonPMitchell (talk) 21:30, 20 November 2011 (UTC)
