Codes and Regulations

The mechanical and electrical installation of PV systems should be performed in accordance with all applicable codes, including electrical codes, building codes and electric utility interconnection requirements. Such require­ments may vary for mounting location. Requirements may also vary with system voltage, and for DC or AC application. Contact local authorities for governing regulations.

General

Product Identification

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 under standard test conditions; Certifications mark, the maximum system voltage etc.
2. Current Sorting: modules are sorted out according to their Max. power current, 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 same “Current class X” class (for example only H Modules) in one given string. For the rest of modules with different current classes, the modules with adjacent current class can be installed in one given string.
3. Serail number: each individual module has a unique serial number. The serial number has 16 digits. The 1st and the 2nd digits are the year code, and the 3th is the month code (A, B, C stands for October, November and December respectively). For example, 121XXXXXXXXXXXXX means the module was assembled and tested in the January of 2012. Each module has only one bar code. It is permanently attached to the interior of the module and is visible from the top front of the module. This bar code is inserted prior to laminat­ing. In addition, you can find the same barcode beside the nameplate.

Conventional Safety

JA Solar 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 equipment.

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 rooftops capable of handling the additional weighted load of PV system components, including modules, and have a complete analysis of the structure performed by a certified building specialist or engineer.

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.

Electrical Performance Safety

Photovoltaic modules can produce DC electricity when exposed to light and therefore can produce an electrical shock or burn. DC voltage of 30 Volts or higher is potentially lethal. Modules produce voltage even when are not connected to an electrical circuit or load. Please use insulated tools and electrically insulated 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 a safety issue with the connection, 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 installation, if the modules are not be installed within a week, rubber connector covers shall be added as a protective measure. Note that 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 or seaside areas with higher salinity or serious polluted areas.

• Reflection from snow or water can increase sunlight and therefore boost current 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 separate the module 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.

Installation must be carried out under the guidance of a qualified electrician.
No matter how weather condition is, personnel entering the power station shall wear safety helmet, insulating gloves and insulating shoes correctly, taking self-safety protection measures.

Operating Safety

• Do not open the package of JA Solar modules until they are ready to be installed during transportation and storing.

• 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 Unpacking Instruction”.

• Do not lift the modules by grasping the module’s junction 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 corner of the modules.

• Inappropriate transport 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.

• 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.
  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.

Fire Safety

• Consult your local authoity for guidelines and requirements for building or structural fire safety. JA solar modules have been in accordance with 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 module backsheet and the mounting surface.
• Roof constructions and installations may affect the fire safety of the building. Improper installation may create hazards in the event of a fire.
• Use appropriate components such as fuses, circuit breaker and grounding connector as requires by local authority.
• Do not use modules where flammable gasses may be generated. JA modules have not been tested for explosion protection. Please consult local regulations whether the modules can be used or not.

Installation position and working environment

• JA Solar modules are intended for use in terrestrial applications, no 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 installed in locations where they could be submerged in water.
• The recommended ambient temperature should be within -40°C(-40° F) to 40°C(104° 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 cannot be installed or used in extreme areas or weather conditions, and highly corrosive areas should be considered careful­ ly.
• Please adopt appropriate measures to ensure the performance and safety of the modules when they are installed or operated in areas heavy snow, extremely cold, strong wind, or near an island or desert that is prone to produce salt fog, or near water.
• JA Solar modules have passed the IEC 61701 salt-mist, 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. JA Solar Modules can be installed at seaside locations 50m to 500m from the sea, but the components should be protected against corrosion. For the detailed requirements, follow JA Solar seaside installation instructions.
• Modules cannot be applied for some special requirements, e.g. for marine and vehicle applications. Please refer to local law and regulations for details.

Tilt Angle Selection

• The tit 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 instaler or systems integrator.
• Dust building up on the surface of the modules can impair module perfomance.
• JA solar recommends instaling the modules with a tilt angle of at least 10 degrees, making it easier for dust to be washed off by rai.

Mechanical Installation

Conventional requirements

Ensure the installation method and supporting system of modules is strong enough to withstand all the load conditions. The Installer 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 international 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 lime. In addition, ensure that the lowest portion of the modules is placed high enough so that ii 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 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 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 (the recommended minimum distance between two modules is 10mm ). The module frames will warp at low temperature.
Avoid the frame receiving the lateral tension and pressure, causing the frame off or crushing the glass.

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 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 modules as ii will result in galvanic corrosion. IEC 60950-1 standard recommends metal combinations not exceed an electrochemical potential difference of 0.6 Volts.

JA Solar modules can be mounted in landscape or portrait orientation. For the bifacial modules, in order to maintain the energy yield of module rear side, the distance between the bottom of modules and the roof or ground surface is recommended be at least 1m.

Installation methods

Modules can be installed to the racks by clamps or hooks. Modules must be installed according to the following examples and recommendation. If not mounting the Modules according to these instructions, please in advance consultJA Solar and must be approved by JA solar, otherwise may damage Modules and void the warranty.

Modules installed with clamp

1. For framed bifacial PERC mono double-glass modules:

A. Module 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, 6063-TS
• Bolt: Stainless Steel, MS
• Nut: Stainless Steel, MS
• Washer: Stainless Steel, MS

B. Recommended bolt torque range: 18N·m to 24N·m.
C. The modules clamps should not contact the front glass or deform the frame in any way. Avoid shading effects from the modules clamps. Drainage holes on the modules frame should not be closed or obscured by the clamps. Besides, two or more screws or two full threads of a single screw shall engage the metal.

Modules installed with mounting hole

Modules should be bolted to support structures through mounting holes located in the frame’s back flanges. Refer to what is shown in Figure 2 (Mounting Details).

For your reference, please use the components specified below:

Bolt

• Material: Q235B/SUS304
• Size and Length: MB*16mm

Washer

• Material: Q235B/SUS304
• Size: MB

Spring Washer

• Material: Q235B/SUS304
• Size: MB

Nut

• Material: Q235B/SUS304
• Size: MB

Recommended torque is between 12N.m to 16N.m.

Installation position and corresponding static loads

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 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 3 times. It means that the maximum dynamic load is 800 Pa when the wind speed is less than 130 km/h.

Electrical Installation

Electrical Property

The rated electrical characteristics, lsc is within +/- 4 % and Voe is within +/- 3 % of measured values at Standard Test Conditions, but for the Pmax, it is within +/- 3%. Standard Test Conditions: 1 000W/m2 lrradiance, 25 t: Cell Temperature and 1.5 Air Mass.

Under normal conditions, the photovoltaic modules may experience conditions that produce more current and/or voltage than reported at Standard Test Conditions. Accordingly, the values of short circuit current, lsc, and open circuit voltage, Voe, 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 module output.

Voltages are additive when modules are connected directly in series, and modules currents are additive when modules are connect­ed directly in parallel, as illustrated in Figure 4.

Modules with different electrical characteristics must not be connected directly in series.

• Series wiring
• Parallel wiring
• Series wiring and Parallel wiring

Figure 4: Electrical diagrams of series and parallel wiring

The maximum number of modules that can be connected in a series string must be calculated in accordance with applicable regulations in such a way that the specified maximum system voltage (The maximum system voltage of JA Solar Modules is DC 1500V according to the safety appraisal of the IEC61730.) of the modules and all other electrical DC components will not be exceeded in open- circuit operation at the lowest temperature expected at the PV system location.

Correction factor for the open-circuit voltage can be calculated based on the following formula: Cvoc =1-voc x(25-T). Tis the lowest expected ambient temperature at the system location. (%/t:) is the temperature coefficient of the selected module Voe (refer to corresponding datasheet).

An appropriately rated over-current protection device must be used when the reverse current could exceed the value of the maximum fuse rating of the modules. An over-current protection device is required for each series string if more than two series strings are connected in parallel, in Figure 4.

Cables and Wiring

These junction boxes have been designed to be easily interconnected in series for their well-connected cable and the connector with IP68 protection grade. Each module has two single-conductor wires, one positive and one negative, which are pre-wired inside the junction box. The connectors at the opposite end of these wires allow easy series connection of adjacent modules by firmly inserting the positive connector of a module into the negative connector of an adjacent module until the connector is fully seated.
Use field wiring with suitable cross-sectional areas that are approved for use at the maximum short-circuit current of the modules. JA Solar recommends installers use only sunlight resistant cables qualified for direct current (DC) wiring in PV systems. The minimum wire size should be 4mm2(12AWG).

Rating Required Minimum Field Wiring

Testing Standard: Wire size Temperature Rating
EN 50618:2014: 4mm2 – 40″C to +90″C

Cables should be fixed to the mounting structure in such a way that mechanical damage of the cable and/or the modules is avoided. Do not apply stress to the cables. The minimum cables bending radius should be 38.4mm. Any cable damage caused by bending too much or cable management system is not covered under JA Solar’s warranty. For fixing, use appropriate means, such as sunlight resistant cable ties and/or wire management clips specifically designed to attach to the module frame. While the cables are sunlight resistant and waterproof, where possible, avoid direct sunlight exposure and water immersion of the cables.

Cable arrangement must comply with local laws and regulations.

Connectors

Keep connectors dry and clean, and ensure that connector caps are hand tight before connecting the modules. Do not attempt making an electrical connection with wet, soiled, or otherwise faulty connectors. Avoid sunlight exposure and water immersion of the connectors. Avoid connectors resting on the ground or roof surface.

Faulty connections can result in arcs and electrical shock. Check that all electrical connections are securely fastened. Make sure that all locking connectors are fully engaged and locked. Connector interconnect must reach the corresponding IP protection level, so as to achieve the electrical security. It is not recommended to interconnect different types of connectors.

Do not contact organic solvents and other corrosive materials in connector connection and the using environment, such as alcohol, gasoline, pesticides, herbicides, etc. Please consult JA for details. Otherwise, JA will not be responsible for connector cracking caused by this aspect. Two examples of incorrect usage are listed below:

Please pay attention that the unlock method of connectors is different according to local laws and regulations.

The junction boxes used with JA Solar modules contain bypass diodes wired in parallel with the PV cell strings. In the case of partial shading, the diodes bypass the current generated by the non-shaded cells, thereby limiting modules heating and performance losses. Bypass diodes are not over-current protection devices.

In the event of a known or suspected diode failure, installers or maintenance providers should contact JA Solar. Never attempt to open the junction box by yourself.

Please pay attention to guard against inductive lightning, backflow and wrong connection.

Grounding

The grounding is only used on the framed bifacial modules. JA Solar modules use an anodic oxidized aluminum frame to resist corrosion. So the frame of modules must be connected to the equipment grounding conductor to prevent thunder and static hurt.The grounding device should fully contact with the inside of the aluminum alloy, and penetrate the surface of the frame oxidation film.

• Please don’t drill any additional grounding hole on the frame of the modules, otherwise JA Solar expressly disclaim liability for voiding the warranty.
• To acquire the best power output, JA recommends clients to install modules with anti-PIO inverter.
• The grounding method should not result in the direct contact of dissimilar metals with the aluminum frame of the modules that will result in galvanic corrosion. IEC 60950-1 standard recommends metal combinations not exceed an electrochemical potential difference of 0.6 Volts.
• The frame rails have pre-drilled holes marked with a grounding sign. These holes should be used for grounding purposes and must not be used for mounting the modules.

The following grounding methods are available.

Grounding by Using Grounding Bolt

There is a grounding hole with 4.2 mm diameter on the edge side closer to the middle of the back frame of the modules. The middle line of the grounding mark is overlapped with the grounding hole, and the direction is same as the longer frame.

The grounding between modules must be approved by a qualified electrician. The grounding device must be produced by a qualified electrical manufacturer. The recommended torque value is 2.3 N.m. 12 AWG copper wire can be used as the equipment grounding conductor in conjunction with the groundingbolt. The copper wire should not be squashed during the installation.

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 hole on the frame. Thread the grounding clamp and the frame with grounding bolt.
• B. Put the toothed gasket into the other side, then tighten and lock the 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 meet the relevant requirements of the national, regional and local code, law and standard.
• D. Finish the mounting with tightening the binding bolt of the grounding wire.

Additional Third-party Grounding Devices
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.

0peration 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 within 2 weeks.

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. It’s usually not dangerous for the accumulated dust to reduce the sunshine, because the light intensity is 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 Module’s 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. It 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.

The visual inspection of the Modules

Inspect 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. If there is burning vestige on the backsheet.

Inspection of the connector and the cable

It’s recommended to implement the following preventive maintenance every 6 months:

• A. Check the encapsulation of the connector with the cable.
• B . Check the sealing gel of the junction box to ensure it is not cracked or creviced.

The installation manual applicable module types are as follows. The module types are subject to changes without prior notice due to continuous product innovation, research and development.
