Use of proper components
Use cable extensions and plugs that are designed for outdoor applications. Ensure that they are in good
electrical and mechanical condition. Only cables with one conductor are to be used.
Ensure that all materials meet the requirements of the systems` maximum voltage, current, moisture, and
temperature when they are exposed to sunlight.
Under normal conditions, a photovoltaic module is likely to produce more current and/or voltage than that
reported under Standard Test Conditions. Accordingly, the values of Isc and Voc marked on the module should
be multiplied by a factor of 1.25 when selecting electrical components voltage ratings, conductor capacities,
fuse type, and type of control components connected to the PV output.
For USA:
Refer to Section 690-8 of the U.S. National Electric Code for an additional multiplying factor of 1.25 which may
be applicable.
The maximum series fuse rating is 15A for both 60 & 72 series modules.
The maximum reverse current is known as series fuse rating multiplied by a factor of 1.35. Each module (or
series string of modules so connected) shall be provided with the maximum series fuse as specified.
Bypass Diodes
When modules in series are partially shaded, it may cause reverse voltage across cells or modules, this may
cause undesirable heating to occur. The use of a diode to bypass the shaded area can minimize both heating
and array current reduction.
All Hanwha SolarOne modules are equipped with factory installed bypass diodes. The factory installed diodes
provide proper circuit protection for the system.
Others
During installation, be sure to tie the cable from the junction box to the mounting substructure with nylon line,
etc. to avoid direct contact of the cable with the back surface of the module.
LIMITED ENVIRONMENTAL CONDITIONS
Hanwha SolarOne`s Limited Warranty for module is based upon modules being mounted in accordance with
following conditions
.
Operating conditions
The operating temperature of Hanwha SolarOne module should be within -40°C to 85°C (-40°F to 185°F).
Ensure adequate ventilation behind the module, especially in hot environments.
Modules should be installed at least 500m from the sea to avoid corrosion due to exposure to salt. Other
sources of corrosion, including Sulfur (Sulfur sources such as volcanoes), can also lead to performance
degradation and should be avoided.
Location conditions
The following locations should be avoided when installing a module:
1.
Location with potential for extreme sand and dust damage
2.
Location with extreme air pollution, chemical vapors, acid rain, and/or soot, etc.
3.
Location with extreme hail and/or snow
4.
Location with potential extreme salt damage
MAINTENANCE AND CARE
Dirt on the surface of solar module may decrease the power generation. Hanwha SolarOne modules have a
self-cleaning function under rainfall weather condition. Module with a mounted tilt angle more than 15
°
is
more effective than other mounting angle. If heavy soiling build-up is excessive on module glass, use a soft cloth
and water for cleaning. CAUTION: DON`T USE ABRASIVE DETERGENTS. Please consult with system designer to
decide the cleaning frequency according to local environmental conditions. Once a year, check the electrical and
mechanical devices to ensure every connection is tight. The system must be periodically inspected.
