Bypass diodes
All modules are equipped with factory installed bypass diodes in the junction box (see table below).
The use of bypass diodes reduces the risk of heating of the shaded cells, limiting the current that can
pass through them and thereby avoiding damage to the cells.

CAUTION: DO NOT
attempt to open the diode housing or junction box located on the back
side of the module. There are no user serviceable parts inside. Opening the junction box may
expose the individual to an electrical shock hazard and will void the warranty.
