  Travis, old boy,

  All you have to do is stop thinking of trackers as a problem. Just
consider them a kind of old age retirement scheme!

  Cheers,

  Matt T

  Hello Again Matt,

  You probably shouldn't try to convince someone from Missouri. (stubborn as
a
  Missouri mule)....

  I'm not saying that a tracked array won't produce more energy than a fixed
  array.  I know it will (until it breaks).  Again, I think trackers are
  really cool. We even plan to install one of the Wattsun dual axis monsters
  (somebody stop me, please) at the new shop we are building right now since
  it will have sunlight from sunrise to sunset whereas our current shop has
a
  very limited solar window.  But that is for me and I'm a gear head.  I
don't
  mind the moving parts.  The sun moves, shouldn't my array?  And I'm
  aggressively looking for a 20kW Jake to rebuild and install at my shop as
  well.  Does anyone have a line on one?  Talk about some maintenance!  But
  that's my own time on my own schedule.

  I'm saying that a tracker will cost me more to support than a fixed array
  and when it's all said in done the customer would have been better off
with
  more modules.  Are you factoring the cost of the out of warranty support
  into the economics of the fixed vs. tracking?  How much do you charge to
  replace a failed controller at a customer that is a two hour drive away?
  And I will not install products for customer knowing that they will break
  within 2 years and within every 2 years thereafter until the end of time.

  You're not going to convince me that trackers are better for my customers.
  I've been putting at least 1200-1400 watts of fixed PV on the SQ Flex's
(900
  watt max draw) we've installed and they are running great meeting the
needs
  as promised with no call backs.  That's what I need.

    Well, I bet the problem I'm having convincing you how I'm right (LOL)
  about this is the kind of pumps you're working with. Or maybe not!
