Ken, Dan, boB and Peter and all,
Thanks for your thoughtful answers. I think if we put superconductors
in outer space aside we know our answer. Of course knowing doesn't help
to sell even one more wire nut! :) Hope all your teams win the
superbowl today!
All the best,

Fellow Scientists,
I got in a discussion with a wrench the other day. He is under the
impression that when a PV module is at short circuit current there is no
voltage. My understanding of electricity is that if there's no voltage
there's no current because current needs voltage in order to
Greg,
All circuits we are working with have resistance and therefore voltage
is required in the circuit. With a shorted module most of the
resistance, and voltage, is within the module itself. A superconductor
could be used externally, connected as close to the module as you like,
and there
is so low compared to normal PV operating
voltages as to be considered zero for all intents and purposes.
