5.7 Conduit
For conduit application, it is necessary to follow the regulation for outdoor installation of conduit. All
fixing parts should be protected from any damage and moisture.
6. Diodes
When there is partial shade on a PV module, reverse-voltage can
occur
inside PV module. In order to
protect this phenomenon, the diodes are normally installed in a Junction Box. HHIGE PV modules are
equipped with bypass diodes. If installer wishes to change into other diodes, the installer should inform
an authorized engineer of HHIGE.
7. Operation and Maintenance
It is required to perform regular inspection and maintenance of the modules, especially within warranty
scope. It is the user’s responsibility to report to the supplier regarding the damages found.
7.1 Cleaning
·
HHIGE modules are designed for long life and require very little maintenance. Under most weather
conditions, normal rainfall is sufficient to keep the module glass surface clean.
·
For AR coating HHIGE modules utilize special materials to increase energy harvest. Always use
clean gloves when handling the module, never touch the glass with bare hands.
·
If dirt build-up becomes excessive, clean the glass surface with room temperature water. Do not use
water with high pressure for cleaning. Do not use harsh cleaning materials such as scouring powder,
steel wool, scrapers, blades, or other sharp instruments to clean the glass surface of the module. Use
of such materials or cleaning will invalidate the product warranty.
·
Do not clean the back of the module. If cleaning the back of the module is required, please contact
local representatives for more detailed information.
·
PV modules will be
“self-clean” as effectively as modules mounted at a 15° tilt or greater.
7.2 Visual Inspection of Modules
·
Inspect the Modules visually to find whether there are appearance defects, the following need to be
paid more attention especially:
1) Whether the glass is broken
2) Corrosion along the cells’ bus-bar
3) Whether there is burning vestige on the back-sheet.
7.3 Inspection of connector and Cable
In order to ensure proper operation of the system, please check all wiring connections and the
condition of the wire insulation periodically.
