Maintenance
To ensure optimum modules performance at project sites near the coastline, we
recommend the following maintenance services once every 3 months:
Inspect the frames, mounting systems, grounding holes and other easily corrodible
1)
areas.
2)
Clean the frames, mounting systems, grounding holes and other areas subject to dust
and salt accumulations.
To maintain and repair installation sites that are rusty and corroded:
1)
Clean up the dust and salt accumulations around the rusty areas.
2)
Spray fluorocarbon varnish on all installations and rusty areas. Make sure that no area
is missed.
3)
For other operation and maintenance guidance, please refer to near-coast
installation standard.

Attentions
Aside from components that are parts of the grounding circuit, all other components
should be insulated from the module frames using non-conductive gaskets.
For fluorocarbon varnish or other chemicals, please follow the instructions strictly,
personal protective equipment (such as goggle, mask, gloves etc) may be needed
during the operation.
No photovoltaic module should be installed within 50 meters from the edge of the
coastline.
In areas between 50 meters and 500 meters from the edge of the nearest coastline,
we recommend ET SOLAR Anti-salt Modules to be used in photovoltaic energy systems
installations.
In areas greater than 500 meters from the edge of the nearest coastline, we
recommend conventional modules to be used in photovoltaic energy systems
installations.

5. ELECTRICAL INSTALLATION

5.1 Grounding

All module frames must be properly grounded.
Observe all local electric codes and regulations.
A bonding or toothed washer is required to make proper and reliable electrical
grounding connection with the anodized aluminum frame.
Devices listed and identified for grounding metallic frames of PV modules are
permitted to ground the exposed metallic frames of the module to grounded
mounting structures.
Consider using a lay-in lug, rated for outdoor use, if the module grounding conductor
is to be larger than #10 AWG.
When using lay-in lugs, the grounding conductor should be inserted into the opening
indicated in the figure, and secured using the set screw.
