Junction Box and Terminals
Modules equipped with one junction box
contain terminals for both positive and
negative polarity, and bypass diodes.
One terminal is dedicated to each polarity
(with the polarity symbols engraved onto
the
body
of
the
junction

DIODES
Bypass Diodes
When the modules in series strings are
shaded partially, it may cause reverse
voltage across cells or modules, because
the current from other cells in the same
series
is
forced
to
shaded area. This may cause undesirable
heating to occur.
The

and array current reduction.
