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
areas.
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:
Clean up the dust and salt accumulations around the rusty areas.
Spray fluorocarbon varnish on all installations and rusty areas. Make sure that no area
is missed.
For other operation and maintenance guidance, please refer to near-coast
installation standard.
Maintenance
3.1.4 Grounding of normal modules
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.
Except for equipment grounding, ET Solar recommends the negative pole of PV module
array is connected to earth during all PV system installations. That will keep optimal
performance of PV Power Plants, which are located in a hot, high humidity climate and
high Maximum System Voltage.
All permanently mounted modules have to be provided with appropriate grounding. The
grounding lug should be suitable for outdoor use with aluminum.The grounding method of
the frame of arrays shall comply with the NEC, article 250 and also meet UL 1703
standard. Lay-in-Lug ground part with 32 threads per inch (e.g., the lay-in-lug with UL file
number E34440, part # GBL-4DBT) should be mounted to one of the 4 mm diameter
grounding holes marked as grounding hole on the frame.
