[pvusers] solar tracking sensor

["john anderson" <john.k.anderson@home.com>]

	Hello

	Does anyone happen to have pointers on either circuit design or circuit
theory for a single axis PV tracking system..I have 99% of my design
completed but have hit a roadblock, the actual sensor that mounts to the PV
tracking mount is getting saturated by ambient daylight, therefore it
assumes that the whole sky is the sun and never homes in on the sun
itself..My design is quite simple and I am using 2 photoresistors aranged in
a sundial type fashion where the angel of the shadow on the  photoresistors
determine rack forward/reverse motion. I have visited a couple of sites that
sell complete tracking systems but they are way out of my price range.Has
anyone attempted this do-it yourself type of project? I have exhausted all
ther major search engines looking for clues.

	Thank You
