6. 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.
6.1 Cautions
·
Do not conduct electrical work such as opening junction boxes or separation of connectors without a
qualified expert.
·
Before electrical work, remove any metal material from body and wear protection equipment for
insulation.
·
To minimize output decline, remove any substance near the PV modules such as grass, moss, and
vine.
·
Any chemical which is not approved by HHGIE shall not contact PV modules.
6.2 Cleaning
·
Recommend maintaining module glass surface clean as possible to improve module power efficiency
and long life.
·
HES 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 HES 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 and soft
materials without potential risks of scratch. 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 backside of the module. If backside cleaning is necessary, 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.
6.3 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 Backsheet.
6.4 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.
