2SAFETY GUIDELINES

2.1 GENERAL SAFETY GUIDELINES

DANGER! Danger due to electric shock!

All installations must be performed in compliance with all applicable regional and local codes, or

other national or international electrical standards as applicable.

A solar module generates electricity and voltage even at low intensity of illumination.

Physically disconnecting contacts in a live electrical circuit can cause arching, resulting in

grave or mortal injury. The severity increases when several modules are connected in series.

Cover the solar modules with opaque material for the entire duration of assembly. Only then is the module reliably de-

energized.

Never disconnect plugs when under load. Be aware that even without the presence of daylight, residual charge may still

be present in the plant. Ensure that the modules are first disconnected from the inverter prior to opening any contacts

in the solar installation.

Artificially concentrated sunlight shall not be directed on the module. Solar modules produce electrical energy when

light shines on their front surface. The DC voltage may exceed 30V. Contact with a DC voltage of 30V or more is

potentially hazardous.

In the case of module or phase voltages of more than 120 V, the extra-low voltage range is left. Undertake the

necessary protective and precautionary measures.

Do not insert electrically conductive parts into the plugs and junction box. Do not touch the contacts or exposed

terminals.

Keep children and unauthorized persons away from the modules.

In case of damaged modules or operational errors of the solar array, always contact your installer or Talesun Technical

Customer Service.

Do not wear metallic ornaments or metallic devices while installing or troubleshooting photovoltaic systems.

WARNING! Danger of injury due to broken glass! Risk of injury due to falling modules!

The modules are primarily made of glass and must therefore be handled with appropriate caution.

In order to ensure safe mounting, familiarize yourself with all applicable national regulations for

work safety and accident prevention.

Wear suitable protective clothing (e.g. safety shoes, protective gloves) in order to prevent injuries.

If the front glass is broken, or the back sheet is torn, contact with any module surface or the frame can cause electric

shock.

2.2 PRODUCT PRECAUTION

Do not attempt to disassemble the modules.

Do not remove any attached nameplates or components from the modules.

Do not open the junction box under any circumstances.

Only carry out modifications to the modules that have been confirmed by Talesun in

writing in advance.

Do not carry out any extra drilling (e.g. for fasteners) on the modules.

Use only insulated tools that are approved for work on electrical installations.

Do not use light concentrators (e.g. mirrors or lenses) to attempt to increase the capacity of the module. The module

may be damaged. This also voids the warranty.

2.3 TRANSPORT AND STORAGE SAFETY GUIDELINES

Inappropriate transport and installation may break the module. To prevent damage of the modules:

Transport the modules in their original packaging until installation.

Store the modules securely in cool and dry rooms. The packaging is not weather-resistant!

Protect the modules against scratches and other damage, especially from impact at the edges or improper storage.

Ensure modules do not bow under their own weight.

Do not rest a module unprotected on its edges. This can damage the module and the frame.

Do not lift or move the modules using the cables or at the junction box under any circumstances!

Do not set the modules down hard on any surface.

Do not subject the module surfaces to mechanical stress.

Do not stand on the modules.

Do not drop or place objects on the modules.

3MECHANICAL INSTALLATION

3.1 SELECTING THE LOCATION

The modules are certified according to the norm IEC 61215 and others for safe operation in moderate climates. The

operator needs to consider the effect of the high altitude on the operation of the module, when the modules are

installed at high altitude.

Do not expose the modules to chemicals.

Do not place the modules in standing water. The junction box is splash-proof only.

Do not install the modules near flammable gases and vapors (e.g. gas containers) or near open flames and flammable

materials. Solar modules are not explosion-proof operating equipment.

If there is exposure to salt (i.e., marine environments) and sulfur (i.e., sulfur sources, volcanoes), there is a risk of

corrosion.

A module is considered shade-free when it is entirely unshaded throughout the year (e.g. by buildings, chimneys,

trees). Even partial shading of the modules (e.g. by overhead lines, dirt, snow) should be avoided.

3.2 SELECTING THE PROPER SUPPORTING FRAME

Always observe the instructions and safety precautions included with the support frames to be used with the modules.

Install each module to a mounting structure:

That is made of durable, corrosion-resistant and UV-resistant material.

That can transfer forces on the module to the assembly substructure.

That ensures that no mechanical stress (e.g. caused by vibrations, twisting or expansion) is generated on the module.

That ensures sufficient back ventilation of the module.

That ensures long term stability.

That will not give rise to galvanic corrosion in case of direct metal contact (i.e. grounding lead, screws, washers, etc.)

That allows for strain-free expansion and contraction due to natural ambient temperature variations.

3.3 GENERAL INSTALLATION

Modules connected in series should be installed at the same orientation and angle. Different orientations or angles may

cause a loss of power output due to the change in sunlight exposure.

When developing the final layout of photovoltaic system, consider keeping suitable access to allow the maintenance

and inspection works. To minimize risk in the event of an indirect lightning strike, avoid forming loops when designing

the system.

The modules may be installed in landscape or portrait format.

Install the module in such a way that the junction box is positioned in

the upper area of the module and the wires hang downwards.

The optimal tilt angle of the module depends on the respective latitude.

We recommend a photovoltaic simulation tool to ensure the optimal

orientation.

Ground mount

Select the height of the mounting system to prevent the lowest edge of the module from being covered by snow for a

long time in winter in areas that experience heavy snowfalls.

In addition, assure the lowest portion of the module is placed high enough so that it is not shaded by plants or trees or

damaged by sand and stones driven by wind.

Roof mount

When installing a module on a roof or building, ensure that it is securely

fastened and cannot fall as a result of wind or snow loads.

Provide adequate ventilation under a module for cooling; the

recommended standoff height is 10cm. Clearance of 1/4 of an inch (6.35

mm) or more between modules is required to allow for thermal expansion

of the frames.

For roof mounting applications the assembly is to be mounted over a fire

resistant roof covering rated for the application. Talesun modules have

been listed as Class C according to UL790 standard.

Any roof penetration required to mount the module must be properly sealed to prevent leaks.

In some cases, a special support frame may be necessary.

The roof installation of solar modules may affect the fireproofing of the building construction.

Do not install modules on a roof or building during strong winds to prevent accidents.

All module support structures used to support PV modules at correct tilt angles should be wind and snow load rated

by appropriate local and civil codes prior to installation.

Pole mount

When installing a module on a pole, choose a pole and module mounting structure that will withstand anticipated

winds for the area.

3.4 INSTALLATION METHOD

(a) Frame Holes Mounting

Modules must be securely attached to the mounting structure using four pre-drilled mounting holes in the frame.

Modules should be bolted to support structures through mounting holes located in the frame's back flanges only. Do

not drill additional holes. Doing so will void the warranty.

Each module must be securely fastened at a minimum of 4 points. If additional wind or snow loads are anticipated for

this installation, additional mounting points should be used. System designer and installer are responsible for load

calculations and for proper design of support structure.

Use appropriate corrosion-proof fastening materials. All mounting hardware (bolt/split washer/flat washer/nut)

should be stainless steel M8 size.

Follow mounting guidelines recommended by the PV mounting supplier. The mounting design must be certified by a

registered professional engineer.

The mounting design and procedures shall comply with local codes and all authorities having jurisdiction.

Use a torque wrench for installation. Tightening torques should be within 10~17 Nm for M8 coarse thread bolts,

depending on bolt quality class.

Ensure that the drainage openings of the frame are left open following installation to allow water runoff. This prevents

frost damage.

Install the module in such a way that rainwater and snowmelt can run off freely to avoid standing water or pudding.

The modules have been designed to resist a static load of 5400Pa (positive load), and this resistance value can

decrease if modules are not mounted following the instructions above.

(b) Clamping installation

Modules can be installed with clamps. Modules must be securely attached to the mounting structure with four clamps on

the long frame.

The modules must be properly secured to their support so that they can withstand live load condition, including wind

uplift, to the pressure they have been certified for. It’s the installer’s responsibility to ensure the clamps used to

secure the modules are strong enough.

The modules are not subject to wind or snow loads exceeding the maximum permissible loads.

The module clamps which are used must not come into contact with the front glass and must not deform the frame.

Avoid shadowing effects from the module clamps. Drain holes in the module frame must not be closed or obscured by

the clamps.

The module installed with clamps on the front frame for 2400Pa load and 5400Pa load (see the following picture), and

refer to the following table for different value of “A”and “B”.

This manual is just for reference. Customer can select the corresponding installation manual based on the purchased

module.

4ELECTRICAL INSTALLATION

4.1 MODULE SELECTION

Only connect modules of the same type, same configurations and same power class in the same system. This is the only way

to achieve optimal yields.

4.2 SAFTY FACTOR

Under normal conditions, a photovoltaic module may experience conditions that produce more current and/or voltage than

reported at Standard Test Conditions. Accordingly, the values of ISC and VOC marked on modules should be multiplied by a

factor of 1.25 when determining component voltage ratings, conductor capacities, fuse sizes and size of controls connected

to the module output.

Alternatively, all valid national regulations for the installation of electrical systems are to be applied.

Installer need to pay more attention to avoid the PID phenomenon, when installing the electrical system.

4.3 GENERAL INSTALLATION

Before installing modules, contact the appropriate authorities to determine permissions, installation and inspection

requirements to follow that apply to your site and installation.

Check applicable building codes to ensure that the construction or structure (roof, facade, support, etc.) where the

modules are being installed is strong enough to support the weight of the modules and all other system components.

If modules are connected in series, the total voltage is equal to the sum of individual voltages. The recommended max.

number of module (N) = Vmax system / [Voc(at STC)/(1.25×1.25) ].

If the modules are allowed to be installed in parallel electrically, each module (or series string of modules so

connected) shall be provided with the maximum series fuse as specified. For applications requiring high currents,

several photovoltaic modules can be connected in parallel; the total current is equal to the sum of individual currents,

each module (or series string of modules so connected) shall be provided with the maximum series fuse as specified.

The recommended number of module in parallel is only one.

Use special solar cable and suitable plugs only (wiring should be placed in conduit that is sunlight-resistant or, if

exposed, should be sunlight-resistant) in accordance with local fire, building and electrical codes. Ensure that they are

in perfect electrical and mechanical condition.

Only use solar cables as connection cables. Use connectors of the same type and manufacturer within a solar system,

and compatible connectors to connect the inverter.

Ensure that all electrical components are in a proper, dry and safe condition. In this way you avoid electrical short-

circuits or dangerous contact voltages due to defective or damaged cables.

Always avoid mechanical stressing of the connection cables.

Ensure a tight connection between the individual connectors (especially to the inverter). Make sure they click together

properly.
