PV panels. For some reason the OP included the thermal group.

Word...

I built over 600 watts of panels from surplus Evergreen cells last
spring, this is back when the cells were less than $0/lb. I just saw an
  Ebay auction for the same cells close at over three times that price.
I got my tempered glass for free and sealed them up in a glass shop as
one would a double pane window (no silicone sandwich, just an airspace
and a dessicant) By the time I was done, I had over $/watt into them
but they haven't been out in the weather yet and I'd be suprised to get
5 years without moisture between the panes.

As for my educational exercise, I wish I had bought a couple of BP
sx170's back when they were about $/watt, rather than spend the hours
and hours it took to solder over 3000 connections by hand, tote these
back and forth to the glass shop, and worry about durability.

I find your analysis to be spot on, and this is from a guy who has been
there-done that.

 Have any of you tried the screen-printing method of creating cells?
The PDFS I have seem pretty simple and cheap if I knew how to
screen-print :)  I'm talking pennies per watt not $.  It seems about
the same as those new flexible panels.

I haven't heard of this method. Can you give the URL to any of these
PDFs? To the best of my knowledge, creating PV cells of any efficiency
and longevity requires the use of fairly exotic equipment.

I wonder what material they think they will screen print with? Maybe
somebody is confused with circuit board etching ....
