▐ 08 MAINTENANCE
Normally, the Modules do not need repair. Follow the maintenance methods below
to ensure the best performance of the Modules:
◊ In most conditions, the normal rainwater can keep the module glass clean. Clean the glass
surfaces with wet soft sponge or cloth if necessary. Use mild non-abrasive cleaning agent
to remove stubborn dirt.
◊ Do not try to clean a Module with broken glass or perforated backsheet. It will cause
serious electrical shock. Take a regular inspection on grounding, mechanical and electrical
connections every 6 months. Make sure all the Module connectors are connected, clean
and without damage or corrosion.
◊ When disassembling the connectors, must make sure all the components are working well;
otherwise the connector’s shall be replaced. Damage on the connector will cause
electronic leakage. The tightening torque of the nut should be 1.5 N • m - 3 N •m.
◊ Use opaque material to completely cover the Modules during repair to avoid electric shock.
When exposed to the sunshine, the Modules will produce high voltage. The repair work
must be carried out by professionals.
Shut down the system before any electric repair. Improper maintenance may
cause electric shock or fire
