Solar Tracker Circuit cheap and easy

PV solar panel single axis solar tracking circuit using CDS photoresistors to sense the position of the sun and convert it to a voltage which drives a single DC motor in either a CW or CCW direction. The circuit is very simple to build and uses cheap parts which can also be recycled from scrap electronics. You can view details of the circuit on greenwatts.info ... the origional circuit design is posted on svsolar's channel and at sunviewenergy.ca.

Have you tested it under sunlight? Our group's having trouble about the LDR or photoresistor not being able to be that sensitive under sun light, any ideas to solve it?

@magnificat19 I havnt tested it lately but I had similar issues with earlier sensors and found by placing a shodow vane between the two sensors works ...

please i wanna do this as my course work for sensors and actuators. do mind helping out?

[helpmonkey]

@155koolkid ... I would be glad to ... pm me if you like

@Aleedogar sure no problem I will send you an email

[anakain125]

can you send me all the data of making this !! i m really love it !! thanks !!

[mrmarvin1995721]

what is the exact value of the transistor,,

[Stizzthebigneptizz]

All I have to say is FOCUS! Not that hard

How large an array will this tracker move?  The motor looks really small but I never say never just because it "looks" small.
