The reason there isn't a lot of interest in broken panels is because
they are very difficult, mostly impossible, to repair. The exceptions
are those with jumper blocks breaking the panel (electrically) into
sections or amorphous glass panels which don't have encapsulants or
internal wiring.

Maybe.  OTOH, maybe it'll put out zero volts.  Either way, if the
glass is broken, the environment can get at the wafers and their
interconnects and corrode them away.  If they do work, they may not
work for long.

 All of the panels that I have seen that he has gotten have produces between
17 and 20 Volts (Open current).  I know that the some of the sun will be
reflected by the glass, but there still has to be some getting through.  He
has several that he has put on his roof, over a year ago, and they all seem
to still be working.  I guess what I am asking, is this:
    Is there any real reason that a system could not be built with these
panels, without "fixing" them?  Leave them in a shattered glass state, and
build a 12 Volt system with them???

Sure. I've heard of some working for years with cracked glass. Since
you apparently have an endless supply of replacements, except for the
nuisance of swapping them out if they die, it sounds like a plan.

 The funny thing is that you still have gotten no real answer.

If the glass is shattered, lay the panel flat on the ground and use a
good quality two part casting resin. The panel I know of that was
repaired this way was broken 9 - 10 years ago after an argument with a
rock.

Free power is free. Why bother to ask?
