<p>Most every industrial grade tracker run off of location and time,
calculates the required array angle. The core code for this is
open source out of NREL (your tax dollars at work). Still over my
pay grade to actually integrate this into a home made tracker.<br>

<div dir="ltr">Hi Wrenches,
<div><br>
</div>
<div>Does anyone know of a non-sensor based tracker controller
that can work with a variety of tracker motors?</div>
<div><br>
</div>
<div>We don't do trackers much but we have a WattSun DuraTrak
controller that has never worked well, we've tried all sorts
of tweaks. Its a tougher location that a lot because there
are high snowy peaks that confuse the tracker I guess.</div>
<div><br>
</div>
<div>It seems like something would be out there that would just
use the sun position equation instead of sensors that can be
confused.</div>

<div>Thanks for your input<br clear="all">
