3.1 Product Identification
Each module has two labels providing the following information:
1. Nameplate: describes the product type; Peak power, Max. power current, Max. power voltage, open
circuit voltage, short circuit current, all as measured under standard test conditions; Certification marks, the
maximum system voltage etc.
2. Barcode: each individual Module has a unique serial number. The serial number has 16 digits. It is
permanently attached to the interior of the Modules and is visible from the top front of the Module. This
barcode is inserted prior to laminating. In addition, you can find a same barcode beside the nameplate.
3.2 Conventional Safety
Xtremesolar Modules are designed to meet the requirements of IEC 61215 and IEC 61730, application class A.
Modules rated for use in this application class may be used in system operating at greater than 50V DC or
240W, where general contact access is anticipated. Modules qualified for safety through IEC 61730-1 and IEC
61730-2 and within this application class are considered to meet the requirements for safety class II
equipments.
When Modules are mounted on rooftops, the roof must have a fire resistant covering suitable for this
application. Rooftop PV systems should only be installed on rooftop that is capable of handling the
additional weighted load of PV system components, including Modules, by a certified building specialist or
engineer and have a formal structure of the complete analysis result.
For your safety, do not attempt to work on a rooftop until safety precautions have been identified and taken
including without limitation fall protection measures, ladders or stairways, and personal protective
equipment.
For your safety, do not install or handle Modules under adverse conditions, including without limitation
strong or gusty winds, and wet or frosted roof surfaces.

3.3 Electrical Performance Safety
Photovoltaic Modules can produce DC electricity when exposed to light and therefore can produce an
electrical shock or bum. DC voltage of 30 Volts or higher is potentially lethal.
Modules produce voltage even when not connected to an electrical circuit or load. Please use insulated tools
and rubber gloves when working with Modules in sunlight.
Modules have no on/off switch. Modules can be rendered inoperative only by removing them from sunlight,
or by fully covering their front surface with cloth, cardboard, or other completely opaque material, or by
working with Modules face down on a smooth, flat surface.
In order to avoid arcs and electrical shock, please do not disconnect electrical connections under load. Faulty
connections can also result in arcs and electrical shock. So please keep connectors dry and clean, and ensure
that they are in proper working condition. Never insert metal objects into the connector, or modify them in
any way in order to secure an electrical connection.
Also in order to avoid the sand or water vapor entering which may cause the connection and safety issue,
the modules need to be installed and connected to the combiner box once they are taken out from the
carton box; keep the connectors dry and clean during the installing. Note that the pollution from sand, dust
and water will result in arcs and electrical shock of connectors We suggest the customers add rubber
connector covers as the protection method specific to the area with heavy dust seaside with higher salinity
or the serious polluted areas.
Reflection from snow or water can increase sunlight and therefore boost currant and power. In addition,
colder temperatures can substantially increase voltage and power.
If the glass or other material is damaged, please wear personal protection equipment and separated the
Modules from the circuit.
Work only under dry conditions, and use only dry tools. Do not handle Modules when they are wet unless
wearing appropriate protective equipment. If you need to clean the Modules, please follow the cleaning
requirements mentioned in the manual.
3.4 Operating Safety
Do not open packages of Xtremesolar Modules during transportation and storing until they are ready to be
installed.
At the same time please protect the package from damage. Do not make the pallets of Modules falling over
directly.
5
Do not exceed the maximum height of pallets to be stacked, as indicated on the pallet packaging.
Store pallets in a ventilated, rain-proof and dry location until the Modules are ready to be unpacked. Please
follow Un-Pack Instructions to unpack the packages of Modules.
Do not lift the Modules by grasping the Module's junction box or electrical cable under any condition.
Do not stand or step on the Modules.
Do not drop the Modules on another Module.
Do not place any heavy objects on the Modules to avoid damaging the glasses.
Be cautious when setting the Modules down on to a surface, especially on the corner of the Modules.
Inappropriate transportation and installation may break the Modules.
Do not attempt to disassemble the Modules, and do not remove any attached nameplates or components
from the Modules.
Do not apply paint or adhesive to the Modules top surface.
To avoid damage to the back sheet, do not scratch or hit the back sheet.
Do not drill holes in the frame. This may compromise the frame strength and cause corrosion of the frame.
Do not scratch the anodized coating of the frame (except for grounding connection). It may cause corrosion
of the frame or compromise the frame strength.
Do not attempt to repair the Modules with damaged glass or back sheet.
3.5 Fire Safety
Consult your local authority for guidelines and requirements for building or structural fire safety.
Xtremesolar Modules have been listed as Class C according to IEC 61730-2 standard.
For roof installations, Modules should be mounted over a fire resistant covering suitable for this application,
with adequate ventilation between the Modules back sheet and the mounting surface.
Roof constructions and installations may affect the fire safety of building. Improper installation may create
hazards in the event of a fire.
In order to maintain the fire class rating, the distance between the Modules frame surface and the roof
surface shall be at least 10 cm.
Use appropriate components such as fuses, circuit breakers and grounding connectors as required by local
authority.
Do not use Modules where flammable gases may be generated.

4. INSTALLATION CONDITION
4.1 Installation Position and Working Environment
Xtremesolar Modules are intended for use in terrestrial applications only-no for outer space use.
Do not use mirrors or other magnifiers to concentrate sunlight onto the Modules.
Modules must be mounted on appropriate mounting structures positioned on suitable buildings, the ground,
or other structures suitable for Modules (e.g. carports, building facades or PV trackers). Modules must not
be mounted on moving vehicles of any kind.
Modules must not be installed in locations where they could be submerged in water.
The recommended ambient temperature should be within -20° C (-4 °F) to 46° C (115° F). The temperature
limits are defined as the monthly average high and low of the installation site. The limit operating
temperature should be-40° C (-40° F) and 85° C (185° F).
Ensure Modules are not subject to wind or snow loads exceeding the maximum permissible loads.
The Modules should be installed in a location where there's no shading throughout the year. Ensure there's
no obstacle to block light near the installation site.
Lightning protection is recommended for PV systems that are to be installed in locations with high
probability of lightning strikes.
Do not use Modules near equipment or in locations where flammable gasses may be generated or collected.
Modules must not be installed nor operated in areas where hail, snow, sand, dust, air pollution, soot, etc.,
are excessive. Modules must not be sited in locations where aggressive substances such as salt, salt mist,
salt-water, chemically active vapors, acid rain, any other type of corrosive agent, could affect the safety and/
or performance of the Modules.
Please adopt appropriate measures to ensure the performance and safety of the Modules when they are
installed or operated in the areas where produces heavy snow, extremely cold, strong wind ,or near the
island or desert where is prone to produce salt fog, or near water.
Xtremesolar Modules have passed salt mist corrosion resistance test according to IEC 61701 , but galvanic
corrosion can occur between the aluminum frame of the Modules and mounting or grounding hardware if
such hardware is comprised of dissimilar metals. Xtremesolar Modules can be installed in seaside that
distance is 50m to 500m between sea, that only stainless steel and aluminum metal directly contact Modules
in seaside installation to limit corrosion. For the detailed requirements need follow Xtremesolar seaside
installation instructions.

4.2 Tilt Angle Selection
The tilt angle of the Modules is measured between the surface of the Modules and a horizontal ground
surface. The Modules generates maximum power output when it faces the sun directly.
In the northern hemisphere, Modules should typically face south, and in the southern hemisphere, Modules
should typically face north.
For detailed information on the best installation angle, please refer to standard solar photovoltaic
installation guides or consult a reputable solar installer or systems integrator.
Dust building up on the surface of the Modules can impair with Modules performance. SFCE recommends
installing the Modules with a tilt angle of at least 10 degrees, making it easier for dust to be washed off by
rain.
5. MECHANICAL INSTALLATION
5.1 Conventional Requirement
Ensure that the installation method and supporting system of Modules is strong enough to make the
Modules to able to withstand all the load conditions. The Installer must provide the guarantee. The
installation supporting system must be tested by the third-party organization with the analysis ability of
Static Mechanical, according to the local national or international standards such as DIN1055 or equivalent
standards.
The Modules mounting structure must be made of durable, corrosion-resistant and UV-resistant material.
Modules must be securely attached to the mounting structure.
In regions with heavy snowfall in winter, select the height of the mounting system. So that the lowest edge
of the Modules is not covered by snow for any length of time. In addition, ensure that the lowest portion of
the Modules is placed high enough so that it is not shaded by plants or trees or damaged by flying sand.
When the Modules are supported parallel to the surface of the building wall or roof, a minimum clearance of
10 mm between the Modules frame and the surface of the wall or the roof is required to allow air to
circulate behind the Modules and to prevent wiring damage.
Do not attempt to drill holes in the glass surface and the Modules frames of the Modules.
Before installing Modules on a roof, ensure that the roof construction is suitable. In addition, any roof
penetration required to mount the Modules must be properly sealed to prevent leaks.
Observe the linear thermal expansion of the Modules frames, must ensure that the minimum distance
between neighboring frames is 10 mm.

Always keep the back sheet of the panel free from foreign objects or structural elements, which could come
into contact with the panel, especially when the panel is under mechanical load.
Modules have been certified for a maximum static load on the back side of 2400 Pa (i.e wind load) and a
maximum static load on the front side of either 2400 Pa or 5400 Pa (i.e. wind and snow load), depending on
the Modules type (please refer to Figure 4 for detailed installation method. )
The mounting method must not result in the direct contact of dissimilar metals with the aluminum frame of
the Modules that will result in galvanic corrosion. Modules can be mounted in landscape or portrait
orientation.
5.2 Installation Methods
Modules can be installed on the frame using mounting holes or clamps. Modules must be installed according
to the following examples and recommendation. If not mounting the Modules according to these
instructions, please in advance consult SF SUNTECH and must be approved by SFCE, otherwise may damage
Modules and void the warranty.
5.2.1 Modules installed with mounting holes

A) Modules should be attached on a supporting structure rail by metal clamps. It is recommended to use the
clamps under the following condition or approved by system installation:
Width: Clamp A no less than 50mm Clamp B no less than 38mm;
Thickness: No less than 3mm;
Material: Aluminum Alloy;
Bolt: M8;
B) Bolt torque requirement: tighten the screws
C) The Modules clamps must not contact the front glass or deform the frame In any way, the contact area of
damp with the front of frame must be smooth, otherwise maybe damage the frame bring about the modules
broken. Avoid shading effects from the Modules clamps. Drainage holes on the Modules frame must not be
closed or obscured by the clamps.

5.2.3 Description of the installation position
The low/normal level of load condition is applicable to the installation in most of environmental conditions:
the maximum static load on the back of the Modules is 2400 Pa (i.e. wind load), and the maximum static
load on the front of the Modules is 2400 Pa (i.e. wind and snow load).
The high level of load condition is applicable to the installation in harsher environmental conditions such as
storm, heavy snow, etc: the maximum static load on the back of the Modules is 2400 Pa (i.e. wind load) and
the maximum static load on the front of the Modules is 5400 Pa (i.e. wind and snow load), depending on the
pressure level that it would endure according to IEC standard.
For the dynamic loads, such as wind, the safety factor needs to be increased by 3 times. It means that the
maximum dynamic load is 800 Pa when the wind speed is less than 130 km/h.
