MAINTENANCE AND CARE
Under most weather conditions, normal rainfall is sufficient to keep the PV module glass surface clean. If dust or dirt
build-up becomes excessive, clean the glass only with a soft cloth using mild detergent and water.
Do not clean the modules with cold water during the warmer hours of the day in order to avoid creating any thermal
shock that may damage the module.
At least once a year, it is recommended to check the torque of terminal screws and the general condition of wiring.
Also, check that mounting hardware is properly torqued. Loose connections will result in damage of the array.
Modules that are replaced must be the same type. Do not touch live parts of cables and connectors. Use appropriate
safety equipment (insulated tools, insulating gloves, etc.) when handling modules.
Cover the front surface of modules by an opaque material when repairing. Modules when exposed to sunlight generate
high voltage and are dangerous.
Trina Solar is a member of the European PV Cycle Association. Through the pre-financed PV Cycle program, Trina Solar
PV modules will be taken back and treated in an environmentally sustainable manner.
WARNING: For any electrical maintenance, the PV system must first be shut down. Improper maintenance can
cause lethal electric shock and/or burns.

BYPASS DIODES AND BLOCKING DIODES
Partial shading of an individual module can cause a reverse voltage across the shaded PV module. Current is then forced go
through the shaded area by the other modules. When a bypass diode is wired in parallel with the series string, the forced
current will flow through the diode and bypass the shaded PV module, thereby minimizing module heating and array current
losses.
Currently, Trina Solar PV modules are equipped with bypass diodes in the junction box. The diode type is SB3040DY,
(rated 40V PIV minimum, 16A minimum, 3 provided). Do not try to open the junction box to change the diodes even if it
malfunctions.
In a system that uses a battery, blocking diodes are typically placed between the battery and the PV module output to
prevent battery discharge at night.
