Solar tracking system for solar panel

Click For Summary

Discussion Overview

The discussion revolves around the development of a solar tracking system for a solar panel weighing approximately 30 kg. Participants explore various mechanisms, control theories, and practical implementations related to solar tracking systems, including efficiency improvements and design considerations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant seeks resources and advice on solar tracking systems, expressing interest in mechanisms and control theory.
  • Another participant questions whether the proposed system is a unique idea or based on existing concepts.
  • A participant references a company, Sedona Solar Technology, which claims a 40% efficiency increase with their tracking systems and expresses interest in exploring cooling methods.
  • It is suggested that obtaining data on the sun's traverse for specific GPS locations could help in designing a motion control system for tracking.
  • Links to home-built solar tracking systems are provided, including one that uses light detectors to follow the sun's brightest point rather than calculating its position.
  • A concept involving a four-sided pyramid with photosensors is proposed to determine the correct elevation and azimuth for the solar panel.
  • A participant mentions a friend, Al Nichols, who built a simple solar tracking system using a photocell, and shares a link to his site.
  • Another participant requests more details about Al Nichols' system, indicating difficulty finding information on his website.
  • A suggestion is made to contact Al Nichols directly for more information about his solar cooker design.

Areas of Agreement / Disagreement

Participants express various ideas and approaches to solar tracking systems, but there is no clear consensus on a single method or design. Multiple competing views and suggestions remain present throughout the discussion.

Contextual Notes

Participants mention different methods and designs without resolving the effectiveness or feasibility of each approach. There are references to specific systems and concepts, but no detailed technical specifications or validations are provided.

Hi everyone i am working on a solar tracking system for a.solar panel that i made wheighting about 30kg , i was wondering where to start looking for books where they may give examples of.such devices with mechanisms and control theory or if.by any chance you have knowledge on the subject and could give me.any advise, that would be awesome:)
Pd : please excuse my grammar.

I like the concept. Is this system already in use or is it your own unique idea?
 
I have only seen on youtube a company called sedona solar technology make tracking systems that claim to increase by 40% the efficiency. I would like to do something similar and even try things like cooling methods.
 
Easiest way is to get data for sun's traverse at different times of year for your GPS location and preset motion control system to track .
 
Here is a home-built solar tracking system which achieves what you're looking for I think: http://www.instructables.com/id/Solar-Tracker-in-the-Internet-Cloud/

Alternatively, this is kind of a cool tracking system which uses 4 light detectors and a pointing system, so it constantly tries to point at the brightest point in the sky (the sun) rather than calculate where the sun will be: http://www.instructables.com/id/Arduino-Solar-Tracker/

Think of a four-sided pyramid. Place it on the solar panel so the edges of the pyramid are parallel to the rotation axiis of the positioner. i.e. the 'top' and 'bottom' sides would be parallel the the Elevation axis. Place a small photosensor on each pyramid face. When the 'top' and 'bottom' sensors have equal output, the Elevation is correct. The same for holds for the Azimuth sensing. As long as the pyramid maintains its orientation relative to the solar panel, it doesn't have to be physically on the solar panel, just attached to the same moving platform. The actual control circuitry can be either analog or digital, whichever is more convenient for you.

My friend Al Nichols built a simple and efficient solar tracking system from a photocell and uses it to keep his solar over in line with the sun.
Here is Al's site: http://www.alnichols.com/

Any details available? I couldn't find any info on his website.
 
Please contact Al Nichols directly.
He used to have full plans for the cooker on his site.
The thing could cook a 20 pound turkey in 4 hours on sun power alone.
