Panel specs have a fuse size mentioned for that application "series fuse rating" eg my Sharp 130w says 15a and so does my Hanwha 230w panel have 15a for that.
( I am not sure all PWM controllers short the panels--the "shunt" type
do, but not sure about the "series" type.) You can short the panel no harm done.
Thanks BFL. After reading that document, it does make sense with parallel strings to have fuses after a certain amount of strings to protect the wiring and panels themselves.
