This video describes a miniature solar tracking robot constructed from servo motors and a micro-controller. This working model can be used to align a small solar panel with the sun

  • Just a though, I think it would be easier to measure the output of the solar panel to find the sun...

  • @tunespt Yes, this would be the most elegant approach, unfortunately the scripting language is limited, making coding for this method complicated.

  • Why didn't you put solar panel on the left side (front view) so that it will be balanced and more stable?

  • @nafativedec

    Yes, the balance would be better with the panel mounted to the left, I ran into some problems with mechanical interference and as the panel is light decided to move it.

  • Very informative dude . Altho i know about microcontrollers i don't know much about photoresistors so maybe another tutorial .

  • Great Vid!

  • I saw this on "the colony experiment" on a larger scale :)

  • @ScienceOnline, @tunespt Actually it wouldn't be elegant at all. It would become more and more impractical and counterproductive as size of application increases. Panel voltage is never exactly the same or constant, and performance reduces with age and/or temperature, not to mention any damage to one SINGLE of the "sensor" panels in the array (hail, dead bird, faulty water seal, etc.) would throw the WHOLE array completely off alignment. Separation of power generation and sensors IS the best.

  • i understood nothing in this video.

    maybe you can make a "science for dummies" version?

  • Arduino?

  • @ScienceOnline Yes, true, the only thing needed was a digital output ampmeter, they are really costly compared to photosensors, going to try this nice nanocpu's to good use :) as I had no knowledge they existed. Thanks!

  • How could this be adapted to move a large solar array (like several square meters)?

  • Great video. I hadn't thought of a separate control tower yet.. This way you could control an array of panels using only a few LDRs

  • Very nice video ; Collective ; what was the total cost of this project Sir.
