== Duplication with [[solar power]] ==


Currently, [[solar power]] as a higher quality article is both redundant and losing viewership, as "solar energy" is a more popular term than "solar power". This article should talk about energy from the Sun in general, not just about it as electricity.

I came to this page and did a word search for "Stirling" and nothing came up. So I added a section on stirling solar after the section on dishes where I thought it most appropriate. Stirling solar is the emerging technology that will take over and dominate the solar power industry. Get up with the times people. If any experts on stirling energy want to add to it, please do. --[[User:Aidan_oz]] <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|undated]] comment was added at 04:42, 24 October 2008 (UTC).</span><!--Template:Undated--> <!--Autosigned by SineBot-->

:: Mrshaba ; I wrote that section somebody has moved it under Concentrating solar power.see history. By the way folks there is an error in that section where its stated "In all these systems a working fluid is heated by the concentrated sunlight, and is then used for power generation or energy storage.[87]" This information is WRONG ! If you look at the very next reference a greenpeace article, it states that concentrating solar power can be converted to electricity in two ways, one by heating a fluid such as oil which is then used to heat steam for a turbine and the other option is a Stirling engine. So under the section concentrating solar power there should be subsections describing which technology is used to couple with dish. There are options !([[Special:Contributions/124.187.32.53|124.187.32.53]] ([[User talk:124.187.32.53|talk]]) 14:39, 25 October 2008 (UTC)) ([[User:Aidan oz|Aidan oz]] ([[User talk:Aidan oz|talk]]) 14:42, 25 October 2008 (UTC))

The main difference between poly crystalline panels and mono crystalline panels?

Ans: the main difference is the panel efficiency, mono crystalline efficiency have reached 23%.

== Blog reference ==


The section on overhead wires and solar panels over carpool lanes needs to be rewritten and find a non-blog reference:
<blockquote>There is a new concept that may be developed by General Motors, Ford and Chrysler in a Manhattan Project approach in return for their Bail Out Money. In this approach Overhead Solar Panels and wires are installed above Diamond Lanes on the nation's freeways. Concurrently, new electric cars are produced that do not require batteries, but are recharged as they run down the Electrified Freeway. This system could also control the navigation of all electric vehicles allowing the driver and passengers to be connected to the Internet getting work done or being entertained.</blockquote>
Also lose the words "Manhattan Project" and "Bail Out Money", and don't capitalize "Overhead Solar Panels" or "Diamond Lanes" and "Electrified Freeway". Also, this is not a "new concept", having been proposed many years before. And you don't do something "in return for bail out money" (such as paying off the Senators voting for it). You keep the company in business in return for bail out money. And it would not involve electric cars that don't have batteries, it would just mean the batteries would not be used during that portion of the trip.

Is it just me, or are the "primary energy use" and "electricity use" numbers completely wrong. I know for a fact that we consume a lot more than 45 TWh in a year. The real number is about 20,000 TWh, and that's of actual electricity off the grid. If you calculate it based on heat content of the fuel that goes into producing that electricity, it's more than twice that.[[Special:Contributions/165.123.122.14|165.123.122.14]] ([[User talk:165.123.122.14|talk]]) 02:25, 9 December 2008 (UTC)

Hmmm... That should be total primary energy use so it appears someone made a conversion error. Good catch. [[User:Mrshaba|Mrshaba]] ([[User talk:Mrshaba|talk]]) 04:36, 11 December 2008 (UTC)

I'm not sure the section on molten salt belongs here, and if it does it should be much shorter and concise. Currently it's a very out-of-place, long-winded description of the tech plus a detailed list of a few experimental concentrated solar power projects that use it. I think this information would be better suited on [[Concentrated_solar_power]] and [[Thermal_energy_storage]]. Also note that while these two technologies were promising several decades ago they are obsolete now for commercial power production thanks to the massive cost decreases of photovoltaic and electric batteries, making the prominence of molten salt on this article seem even less appropriate on a general article about solar energy.

This is true. But only if the concept of finite / infinite is discarded.

This concept is flexible. It is quite normal, for example in botanical studies to say, the "number of petals in this flower is infinite", if the number crosses 25 or 30.

Similarly, the number of celestial bodies is normally considered infinite, though it can definitely be counted given enough time and resources. In the latter sense, hydrogen supply in the sun is infinite. Even technically we do not know enough to say that it is non-renewable.

In any case, if it merits space under this subject it definitely needs to be a. relocated and b. argued and referenced.

Latest revision as of 13:04, 16 October 2024

Former good articleSolar energy was one of the Engineering and technology good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.
