Maintenance
•
Do not make modifications to any component of the PV
module (diode, junction box, connectors or others).
•
Regular maintenance is required to keep modules clear of
snow, bird droppings, seeds, pollen, leaves, branches, dirt
spots, and dust.
•
Modules with sufficient tilt (at least 15°), generally may
not require cleaning (rain will have a self-cleaning effect).
If the module has become soiled, wash with water and a
non-abrasive cleaning implement (sponge) during the
cool part of the day. Do not scrape or rub dry dirt away, as
this may cause micro scratches.
•
Snow should be removed using a soft brush.
•
Periodically inspect the system to check the integrity of
all wiring and supports.
•
To protect against electric shock or injury, electrical or
mechanical inspections and maintenance should be
performed by qualified personnel only.

Module Cleaning Guidelines
•
This manual covers the requirements for the cleaning
procedure of PV modules of DMEGC Solar. The purpose of
these cleaning guidelines is to provide general
information for cleaning DMEGC Solar
’s
modules. System
users and professional installers should read these
guidelines carefully and strictly follow these instructions.
•
Failure to follow these instructions may result in death,
injury or damage to the photovoltaic modules. Damages
induced by inappropriate cleaning procedures will void
DMEGC Solar
’s
warranty.
Safety Warning
•
Cleaning activities create risk of damaging the modules
and array components, as well as increasing the potential
electric shock hazard.
•
Cracked or broken modules represent an electric shock
hazard due to leakage currents, and the risk of shock is
increased when modules are wet. Before cleaning,
thoroughly inspect modules for cracks, damage, and
loose connections.
•
The voltage and current present in an array during
daylight hours are sufficient to cause a lethal electrical
shock.
•
Ensure that the circuit is disconnected before starting the
cleaning procedure as contact with leakage of electrically
active parts can result in injury.
•
Ensure that the array has been disconnected to other
