JA SOLAR INSTALLATION MANUAL 01

1. Product ldentification
Each module has three 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 understandard test conditions; Certifications mark,the maximum system voltge etc.
2. Current Sorting: Modules are sorted out according to their Max. powercurrent, referred as a corresponding symbol "Current class
X" attached, in which x takes the value H, M or
L(H marks physically the highest current). To get optimal performance out of a string of
Modules it is recommended to connect only Modules of the sama "Current class X" class (for example only H Modules) in one given
string.We recommend the modules with
and without LRF should notbe installed in a inverter, even if they are the same currentclass. For
the rest
of modules with differentcurrent classes, the modules with adjacent current class can be installed in onegiven string.
3. Serial number: each individual module has a unique serial number. The serial number has 16 digits. The 1stand the 2nd digits are
the year code,
and the 3th is the month code {A, B, e stands for October, November and December respectively). For example,
121XXXXXXXXXXXXXmeans the module was assembled and testad in the January of 2012. Each module has only one barcode. lt is
permanentlyattached
to theinterior of the module and is visible from the 1Dp front ofthe module. This barcode is insertad priortolaminating. 1n
addition, you can find the same barcode beside the nameplate.
2. Conventional Safety
JASolar Modules are designad to meet the requirements of IEC 61215 and IEC 61730, application classA. 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 forsafetythrough I
EC 61730-1 and IEC 61730-2 and within this application classareconsidered to meetthe requirements
for safety class
II equipment.
When Modules are mounted on rooltops, the roofmusthave a fire resistant covering suitableforthis application. Rooltop PVsystems
should only
be installed on rooftops capable ofhandling the additional weighted load of PVsystem components, including Modules, and
have a complete analysis ofthe structure performed by a certified building specialist
or engineer.
Foryoursafety,
do notattempttoworkon a rooftop until safetyprecautions have been identified and taken, includingwithout limitation:
fall protection measures, ladders or stairways, and personal protective equipment.
For your safety, do not instan or handle Modules underadverse conditions, including without limitation strong or gusty winds, and wet
or frosted roofsurfaces.
3. Electrical Performance Safety
Pho1Dvoltaic Modules can produce DC electricity when exposed to light and therefore can produce an electrical shock or burn. DC
voltage of30 Volts or higher is potentially lethal.
Modules produce voltageeven when not connected
to an electrical circuit or load. Please use insulatedtools and electricallyinsulated
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 byfully covering their
front surfacewith cloth, cardboard,
or other completely opaque material, or byworking with Modules face down on a smooth, flat surface.
In order to avoid ares and electrical shock, please do notdisconnect electrical connections underload. Faulty connections
can also
result in ares and electrical shock. So pisase keep connectors dryand clean, and ensure thattheyare
in properworking condition. Nevar
insert metal objects intothe connector, or modifythem in anywayin orderto secure an electrical connection.
Also in arder to avoid the sand
or water vapor entering which may cause a safety issuewith the connection, the modules need to be
installed and connected to the combiner box once they are taken outfrom the carton box, keep the connectors dryand clean during the
installation, ifthe modules are not be installed within a week, rubber connectorcovers shall be added as a protective measure. Note that
pollution from sand, dustand waterwill result in ares and electrical shock
of connectors. We suggest the customers add rubber connector
covers
as a protection method specific to the area with heavy dust or seaside areas with highersalinity or serious polluted areas.
Reflection from snow
or water can increase sunlight and therefore boost current and power. In addition, colder temperaturas can
substantially increase voltage and power.
lf the glass or othermaterial is damaged, please wear personal protection equipment and separate the module from the circuit.
No matter howweather condition is, personnel entering the power station shall wear safety helmet, insulating gloves and insulating
shoes correctly, taking self-safety protection measures.
JA SOLAR INSTAI..LATION MANUAL 02

Work only under dry conditions, and use only dry tools. Do not handle Modules when they are wet unless wearing appropriate protective
equipment. lf
you need to clean the Modules, please follow the cleaning requirements mentioned in the manual.
lnstallation must be carried out under the guidance ofa qualified electrician.
1 4. Operating Safety
Do not open the package of JA Solar Modules during
transportation and storing until they are ready to be
installed.
At the same time please protect the package against
exposure to damage. Secure pallets from falling over.
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 unpack the package of JA Solar Modules
according to "JA Solar Modules Un-Pack lnstruction".
Do not lift the Modules by grasping the Module'sjunction
box or electrical leads
in 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
glass breakage.
Be cautious when setting the Modules down on to a
surface, especially on the comer of the Modules.
lnappropriate transport and installation may break the
Modules.
Do not attemptto 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 backsheet, do not scratch or hit the
backsheet.
Do not drill hales 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). lt may cause corrosion
of the frame or
compromise the frame strength.
Do not attempt to repair the Modules with damaged glass.
The scrapped modules shall be recovered and disposed by the
qualified institution.
In dry areas, modules are easily affected by static electricity
during installation. So the installation personnel should wear
anti-static assembly to ensure that the equipment and installation
personnel are not affected or hurt by static electricity.
JASOLAR INSTALLATION MANUAL 03

1. lnstallation position and working environment
JA Solar Modules are intended for use in terrestrial applications only-no outerspace use.
Do not use mirrors or other magnifiers to concentrate sunlight onto the modules.
Modules mustbe mounted on appropriate mounting structures positioned on suitable buildings, theground,
or otherstructuressuitable
for modules (e.g. carports, building facades or PV trackers).
Modules must not be installed in locations where they could be submerged in water.
The recommended ambient temperature should be within -40ºC(-40ºF)
to 40ºC(104ºF).The temperature limits are defined as !he
monthly average high and low
of the installation site. The limit operating temperature should be-40 ºC (-40ºF) and 85ºC (185º F).
Ensure Modules are notsubject 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 li
ght
nearthe installation site.
Lightning protection is recommended for PVsystems that are to be installed in locations with high probability
of lightning strikes.
Do not use Modules nearequipment
or in locations where flammable gasses maybe generated or collected.
Modules cannot be installed
or used in extreme areas or weatherconditions, and highlycorrosive areas should be considered careful-
ly. Please adopt appropriate measures to ensure the performance and safety
of the Moduleswhen they are installed or operated in areas
with heavy snow, extremely cold, strong wind,
ornearan island or desert that is prone to produce sal!fog, ornear water.
JASolar Moduleshave passed the IEC 61701 salt-mist, bu!galvaniccorrosion can occurbetween thealuminum frame ofthe Modules
and mounting
or grounding hardware if such hardware is comprised of dissimilar metals. JA Solar Modules can be installed al seaside
locations 50m to 500m from the sea, butthe components should be protected against corrosion. For!he detailed requirements, follow
JA
Solarseaside installation instructions.
The moduleswith LRF can have sorne light reflections
at certain angles and lightpollution if there are provisions in place, an assess-
ment bythe planner might be needed.
Modules cannot be applied
for sorne special requirements, e.g. for marine and vehicle applications. Please refer to local law and
regulations for details.
JA SOLAR INSTALLATION MANUAL 04

5. Mechanical lnstallation
1. Conventional requirements
Ensure the installation method and supporting system of Modules is strong enough to withstand all the load conditions. The lnstaller
must provide this 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 intemational 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 portien 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 a building wall or roof, a minimum clearance of 10 cm between the Module
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 as this will void the warranty.
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 10mm.
The module frames will warp at low temperatura.
Avoid the frame receiving the lateral tension and pressure, causing the frame off
or crushing the glass.
Always keep the module backsheet 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 either2400 Pa or 5400 Pa(i.e. wind and snow load), depending on the modules type (please refer to the following installation
methods for details).
The mounting method must not result in the direct contact
of dissimilar metals with the aluminum frame of the Module as it will
result in galvanic corrosion. IEC 60950-1 standard recommends metal combinations not exceed an electrochemical potential
difference
of 0.6 Volts.
Modules can be mounted in landscape or portrait orientation.
JA SOLAR INSTALLATION MANUAL 05

3. lnstallation position and corresponding static loads
The low/normal level ofload 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 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 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 3times. lt means that the
maximum dynamic load
is 800 Pa when the wind speed
is less than 130 km/h.

Standard
Test Conditions. Standard Test Conditions: 1 OOOW/m
2 lrradiance,
25 ·e Cell Tempertature and 1.5Air Mass.
Undernormal
conditions, the photovollaicModules may experience conditions lhat produce more current and/or voltage than reported et
Standard Test Conditions. Accordingly, the values ofshortcircuit current, lsc, and open circuit voltage,
Voc, marked on Modules should
be multiplied by a factor
of 1.25 when determining component voltage ratings, conductor capacities, fusing sizes, and size of controls
connected to the Modules output.
Voltages areadditive when Modules are connected directly
in series, and Modulescurrents are additive when Modulesareconnected
direc11y in parallel, as illustrated in Figure 5.
Modules with different electrical characteristics must not be connected directly in series.

The
maximum number of Modules that can be connected in aseries string must be calculated in accordance with applicable regulations in
such a way that the specified maximum system vollage (The maximum system voltage of JA SolarModules is DC 1 OOOV/1 SOOV according to
the safety appraisal of the IEC61730) of the Modules and all otherelectrical DC components will not be exceeded in open-circuit operation et
the lowest temperatura expected atthe PV system location.
Correction factor for the open-circuit voltage can be calculated basad on the following formula: c....=1 ~x(25- n. T is the lowest expected
ambient temperature at the system location. 13(%/C) is the temperature coefficient of lhe selected module Voc (refer to corresponding

Thegroundlng method should notresuttInthedlrectcontactofdlsslmllarmetalswlth thealumlnum frame of the Modulesthatwlll result
in galvanic corrosion. IEC 60950-1 standard recommends metal combinations notexceed an electrochemical potenlial difference of0.6
Volts.
The frame rails have pre-drilled holes marked wilh a grounding sign. These holes should
be used forgrounding purposes and should
not
be used for mounling the Modules.
The following grounding melhodsare available.

line
of the grounding mark isovertapped wilh thegrounding hola, and the direction is same as the longarframe.
The grounding between Modules must be approved
by a qualified electrician. The grounding devioe should produoed by a qualified
electrical manufacturar. The recommended torque value is 2.3 N.m. A 12 AWG copper wire can be used as the equipment grounding
conductor
in conjunction with the grounding bolt. The copperwire should not be compressed during the instellalion.

2. Grounding by using unused mounting hole
The existing mounting holes which have not been used can be used for grounding.
A. Direct the grounding clamp
to the mounting holes in the trame. Thread !he grounding
clamp and the frame with grounding bol!.
B. Pul the toothed gasket into the other side, then tighten and lock !he nut. The
recommended torque of locking the nut is 2.0 N•M-2.2 N•M.
C. Thread the grounding clamp with grounding wire. The materiel and size
of grounding
wire should meetthe relevant requirements
of the national, regional and local code, law and
standard.
D. Finish the mounting with tightening the binding bolt of grounding wire.

JA Solar Modules can be grounded using third party grounding devices so long as they are certified for grounding modules and
the devices are installed according
to the manufacturer's specified instructions.
8.0peration and Maintenance
lt is required to perform regular inspection and maintenance of the Modules, especially within warranty scope. lt is the user's
responsibility
to report to the supplier regarding the damages found within 2 weeks.
1.Cleaning
The dust accumulated on the front transparent substrate may reduce the power output, and may even cause regional hot-spot
effect. Industrial effluents
or bird drops may be a serious case, and the extent of the severity depends on the transparency of the
foreign objects. lt's usually notdangerous forthe accumulated dust to reduce the sunshine, because the light intensityis still homogeneous
and the power reduction usually is
not obvious.
When Modules are operational, there may exist environmental factors that cast dust, plants and so on, that may distinctly reduce
the power output.
JA Solar advises that there should be no obstructed object over the Modules surface at any time.
The cleaning frequency depends on the accumulating velocity
of the fouling. In many instances the front substrate is cleaned with
the rain, and
we can decrease the cleaning frequency. lt is recommended to wipe the glass surface with wet sponge or soft cloth.
Please do not clean the glass with cleaning agent which contains acid
or alkali.
Please refer to "cleaning manual" for specific contents.
2.The visual inspection of the Modules
lnspect the Modules visually to find if there are appearance defect, the following three types need more attention especially:
A. Whether the glass is broken;
B. Corrosion along the cells' bus-bar. The corrosion is caused by the dampness infiltrated into the Modules when the surface
encapsulation material is damaged during the installation
or transportation.
C. lf there is burning vestige on the backsheet.
JASOLAR INSTALLATION MANUAL 12

3.lnspection of the connector and the cable
lt's recommended to implement !he following preventive maintenance every 6 months:
A. Check !he encapsulation of !he connector with !he cable.
B.Check the sealing
gel of the junction box to ensure it is not cracked ar creviced.
