Talk:Solar tracker

message: I had previously added a link to a global directory of solar tracker manufacturers (http://www.enf.cn/database/components-tracker.html).  The information was taken down by someone who hadn't actually reviewed the validity of the information but was deleting based on the fact that I posted up several links to ENF.
On the suggestion of one of person that removed the information, I am submitting suggested comments/links here in the hope that other editors will evaluate the relevance and resubmit it to the main page:

replies: text: External links to promote manufacturers (Business-side info) is covered in WP:ELNO #5. Also Wikipedia is not a directory (WP:NOT). All such links have been removed on these grounds. Fountains of Bryn Mawr (talk) 00:58, 2 April 2008 (UTC)
thread_title:  Business-side info 

message: The following sentence is meaningless if no additional info is provided: <<A single axis tracker increases annual output by approximately 30%, and a dual axis tracker an additional 6%.>>
I'll remove it unless someone convinces me not to.

replies: text: A quick GBS search supports the idea generally of increases in that range over non-tracked designed.  One book says "up to 40%" increase; another says single-axis 20 to 30%.  I didn't find a source for those particular numbers, but it would be better to edit it to something sourced than to just throw it out.  Or fact tag it to give others a chance to work on it.

replies: text: I agree that tracking increases efficiency. However, there is no such thing as a "single axis tracker". If you read the article, it is apparent that there are at least two ways of having a single axis system: either oriented along a North-South axis or oriented vertically.82.229.209.33 (talk) 23:51, 26 February 2008 (UTC)

text: Claims about increasing the efficiency are related to flat devices (PV or thermal). In the case of CSPs, the trackers do not increase efficiency but rather are essential to operation. Without the tracker, the CSP would only "work" once a day as the sun passed into focus.George Plhak (talk) 11:06, 18 November 2010 (UTC)
replies: text: I assumed that single-axis designs aimed at good efficiency would be equatorial-axis, but that's not even mentioned in the article.  Horizontal and vertical wouldn't be expected to do nearly so well, I bet, unless you're at very high or very low latitude. Dicklyon (talk) 01:42, 27 February 2008 (UTC)
replies: text: The single axis backyard trackers shown approximate closely enough (for practical purposes) an equatorial-axis tracker, which would be considerably more expensive to produce, likely more expensive than an appropriately operated two-axis tracker. -Leonard G. (talk) 00:00, 12 September 2008 (UTC)

text: No such thing? Single axis refers to the number of axis for daily driving of the tracker (not to seasonal adjustments in the case of a single axis system). The backyard passive trackers and the Gemini House both are single axis trackers. - Leonard G. (talk) 00:00, 12 September 2008 (UTC)
thread_title:  Efficiency increase 

message: I'm not the one who created this section, but I read in the Walled garden article (I think) in a discussion of fruit walls that in the late 1600s someone discussed using a solar tracker to improve upon the sloped fruit wall design. This article would benefit from a section on low-cost, low-tech, and/or old-tech solutions. I also remember seeing a low-cost solar tracker in the cable tv show, Invention Nation. http://science.discovery.com/fansites/invention-nation/invention-nation.html
Sorry I can't contribute more. Hope this helps a little. Geekdiva (talk) 21:51, 21 May 2010 (UTC)

thread_title:  External links modified (January 2018) 

message: horizontal single horizontal axis tracker moves 180 degrees from east to west in 12 hours. I get that.
Dual axis tracker moves north and south when exactly? A little bit each day, or continuously through the day? 
Does the sun move in a straight path through the sky each day, or curved?
A dual axis tracker is a combination of horizontal and vertical axis? Or only the azimuth–altitude type?
And the third axis, the third degree of freedom?
There are two horizontal axis and one vertical. 
The article mixes them up and fails to clearly explain which type of trackers move in which way, on which of the three axis, when and how.
