CONNECTORS
•
Keep connectors dry and clean. Ensure that
connector caps are hand-tight before connecting
the modules.
•
Do not attempt to make an electrical connection
with wet, soiled, or otherwise faulty connectors.
•
Avoid sunlight exposure and water immersion of
the connectors. Avoid allowing connectors to rest
on the ground.
•
Ensure cable connectors are UL and Canadian
code complaint.
•
Faulty connections can result in arcs and
electrical shock.
•
Check that all electrical connections are securely
fastened.
•
Make sure that all locking connectors are fully
engaged and locked.
11.4
DIODES
•
The junction boxes used with Mission Solar
Energy modules contain bypass diodes wired in
parallel with the PV cell strings.
•
In the case of partial shading, the diodes bypass
the current generated by the non-shaded cells,
thereby limiting modules heating and
performance losses. Bypass diodes are not over-
current protection devices.
•
Bypass diodes divert current from the cell strings
in the event of partial shading. In the event of a
known or suspected diode failure, installers or
maintenance providers should contact Mission
Solar Energy.
•
Never attempt to open the junction box.

MAINTENANCE
12.1
VISUAL INSPECTION
Mission Solar Energy recommends that PV systems be
periodically inspected by the installer or other qualified
personnel. The purpose of the PV system inspection is to
ensure that all system components are functioning
properly. At a minimum, this inspection should confirm the
following:
•
All cables and connector attachments are undamaged
and properly secured.
•
No sharp objects are in contact with the PV module
surfaces.
•
PV modules are not shaded by unwanted obstacles
and/or foreign material.
•
Mounting and grounding components are tightly
secured with no corrosion.
•
Defects should be addressed immediately.
12.2
CLEANING
•
The dust accumulated on the front transparent
substrate may reduce the power output, and may
even cause regional hot-spot effect.
•
It’s usually not dangerous for the accumulated dust to
reduce the sunshine because the light intensity is still
homogeneous and power reduction is not usually
obvious.
•
When modules are installed, avoid environmental
influence factors that cast shadows and cover part or
all of the modules. This includes other modules,
system support, bird drops, dust, and so on. This
debris may distinctly reduce the power output.
•
The cleaning frequency depends on the accumulation
frequency and can vary from 6 months to 2 years. Do
not use alkaline, abrasive, alkali or acid materials,
detergents, or cleaning solutions to clean the module.
•
It is recommended to wipe the glass surface with a
wet sponge or soft cloth. Please do not clean the glass
with a cleaning agent which contains acid or alkali.
