1. Purpose of this guide

■

This is guide contains information regarding the installation and safe handling of

Powerark Solar Pty Ltd photovoltaic module (hereafter referred to as “module”).

Powerark Solar Pty Ltd photovoltaic module referred to as “Link Energy”.

■

Installers must read and understand this guide prior to installation. For any questions,

please contact our Global Quality & Customer Support department for further

information. Installers should follow all safety precautions described in this guide as

well as local codes when installing a module.

■

Before installing a solar photovoltaic system, installers should familiarize themselves

with its mechanical and electrical requirements. Keep this guide in a safe place for

future reference(care and maintenance) and in case of sale or disposal of the

modules.

1.1 General safety

■

Modules that fall under this application class may be used in system operating at more

than 50V DC or 240W, where general contact access is anticipated. Modules qualified

for safety under IEC 61730-2 and within this application class are considered to meet

the requirements for Safety Class II.

■

Installing solar photovoltaic systems requires specialized skills and knowledge.

Installation should only be performed by qualified persons.

■

Installers should assume all risks of injury that might occur during installation,

including, but not limited to, the risk of electric shock.

■

One single module may generate more than 30V DC when exposed to direct

sunlight. Contact with a DC voltage of 30V or more is potentially hazardous.

■

Do not disconnect under load.

■

Photovoltaic solar modules convert light energy to direct current electrical energy.

They are designed for outdoor use. Modules can be ground mounted, mounted on

rooftops, vehicles or boats. The proper design of support structures lies within

responsibility of the systemdesigners and installers.

■

Do not use mirrors or other magnifiers to concentrate sunlight onto the modules.

■

When installing the system, abide to all local, regional and national statutory regulations.

Obtain a building permit if necessary.

■

This product must be installed by a licensed electrician in accordance with the applicable

electrical code (i.e. the NEC for the USA and CEC for Australia).

■

Only use equipment, connectors, wiring and support frames suitable for solar electric

systems.

1.2 Handling safety

■

Do not lift the module by grasping the module’s junction box or electrical leads.

■

Do not stand or step on the module.

■

Do not drop the module or allow objects to fall on the module.

■

To avoid glass breakage, do not place any heavy objects on the module.

■

Be cautious when setting the module down on to a surface.

■

Inappropriate transport and installation may break the module.

■

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 module top surface.

■

To avoid damage to the backsheet, do not scratch or hit the backsheet.

■

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.

■

Be careful when setting the panel down onto a surface, particularly when placing it on a

corner.

■

A panel with broken glass or torn backsheet cannot be repaired and must not be used

since contact with any panel surface or the frame can cause an electric shock.

■

Work only under dry conditions, and use only dry tools. Do not handle panels when

they are wet unless wearing appropriate protective equipment.

■

When storing uninstalled panels outdoors for any period of time, always cover the panels

and ensure that the glass faces down to stop water from collecting inside the panel and

causing damage to exposed connectors.

1.3 Installation safety

■

Any module without a frame (laminate) shall not be considered to comply with the

requirements of IEC standard unless the module is mounted with hardware that has

been tested and evaluated with the module under this standard or by a field

Inspection certifying that the installed module complies with the requirements of IEC

standard.

■

Never open electrical connections or unplug connectors while the circuit is under load.

And do not disconnect during load connection for a removable connector.

■

Contact with electrically charged parts of the panels, such as terminals, can result in

burns, sparks and lethal shock whether or not the panel is connected.

■

Do not touch the PV module unnecessarily during installation. The glass surface and

the frame may be hot; there is a risk of burns and electric shock.

■

Do not work in the rain, snow or in windy conditions.

■

Avoid exposing cables to direct sunlight in order to prevent their degradation.

■

Keep children well away from the system while transporting and installing

mechanical and electrical components.

■

Artificially concentrated sunlight shall not be directed on the module or panel. And

completely cover the module with an opaque material during installation to prevent

electricity from being generated.

■

Do not wear metallic rings, watchbands, ear, nose, lip rings or other metallic

objects while installing or troubleshooting photovoltaic systems.

■

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

■

Follow the safety regulations for all other system components, including wires

and cables, connectors, charging regulators, inverters, storage batteries,

rechargeable batteries, etc.

■

Under normal conditions, a photovoltaic module is likely to experience conditions that

produce more current and/or voltage than reported at standard test conditions.

Accordingly, the values of ISC and VOC marked on this module should be multiplied

by a factor of 1,25 when determining component voltage ratings, conductor current

ratings, fuse sizes, and size of controls connected to the PV output.

■

Only use connectors to connect modules to form a string, or connect to another device.

Removing the connectors will make the warranty void.

■

Installation shall be at an incline of 127 mm per 300 mm; except that built-up roof

coverings are to be tested at the maximum incline recommended by the manufacturer,

but not more than 127 mm to 300 mm.

1.4 Fire Safety

■

The fire rating of this module is valid only when mounted in the manner

specified in the mechanical mounting instructions.

■

Consult your local authority for guidelines and requirements for building or structural fire

safety.

■

Roof constructions and installations may affect the fire safety of a building; Improper

installation may create hazards in the event of a fire.

■

Use components such as ground fault circuit breakers and fuses as required by local

authority.

■

Do not use panels near equipment or in places where flammable gases may be generated.

■

The modules have been rated Fire Class C.

2. Product Identification

Each module has two labels providing the following information:

Nameplate: describes the product type; rated power, rated current, rated voltage,

open circuit voltage, short circuit current, all as measured under standard test

conditions; weight, dimensions etc.; the maximum system voltage of 1000V DC or

1500V DC.

Barcode: Each individual module has a unique serial number. The serial number

has 18 digits. The fifth and sixth digits shows the year code and the seventh and the

eighth digits are the month code; The ninth digit and the tenth digits shows the

product ID; The fifteenth to eighteenth digits, these four digits show the serials

number of the module. Each module has only one barcode. It is permanently attached

to the interior of the module and is visible from the front of the module. This bar

code is inserted prior to laminating.

Do not remove any labels. Removing a label will make the Link Energy warranty void.

3. Mechanical Installation

3.1 Selecting the location

■Select a suitable location for installing the modules.

■The modules should be facing south in northern latitudes and north in southern latitudes.

■For detailed information on the best installation angle, refer to standard solar photovoltaic

installation guides or consult a reputable solar installer or systems integrator.

■The module should not be shaded at any time.

■Do not use modules near equipment or in locations where flammable gases may be

generated or collected.

3.2 General Installation

■The module mounting structure must be made of durable, corrosion-resistant and UV-

resistant material.

■In regions with heavy snowfall in winter, select the height of the mounting system so that

the lowest

edge of the module is not covered by snow for any length of time.

■

In addition, ensure that the lowest portion of the module is placed high enough so that it

is not shaded by plants or trees or damaged by flying sand.

■

Modules must be securely attached to the mounting structure.

■

Provide adequate ventilation under the modules in conformity to your local regulations.

A minimum distance of 10 cm between the roof plane and the frame of the module is

generallyrecommended.

■

Always observe the instructions and safety precautions included with the module support

frames.

■

Do not attempt to drill holes in the glass surface of the modules as this will void the warranty.

■

Do not drill additional mounting holes in the module 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 module must be properly sealed to prevent leaks.

■

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

withstand the anticipated winds for the area.

■

Dust building up on the surface of the module can impair with module performance. We

recommend installing the modules with a tilt angle of at least 10 degrees, making it easier

for dust to be washed off by rain.

■

Observe the linear thermal expansion of the module frames(the recommended minimum

distance between two modules is 2 cm).

■

Always keep the backsheet 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.

■

Ensure panels are not subjected towind or snow loads exceeding the maximum permissible

loads, and are not subject to excessive forces due to the thermal expansion of the support

structures: See the following paragraph for more detailed information.

3.3 Installation methods

■

Common hardware items such as nuts, bolts, star washers, lock washers and the like have

not been evaluated for electrical conductivity or for use as grounding devices and should be used

only for maintaining mechanical connections and holding electrical grounding devices in the proper

position for electrical conductivity. Such devices, where supplied with the module and evaluated

through the requirements in IEC standard, may be used for grounding connections in accordance

with the instructions provided with the module.

■

We suggest each module be securely fastened at 8 points (14mm×9mm) with Screw Fitting

Method (Figure 1) using mounting holes or 4 points with Clamping System (Figure 2).

■

Modules must be installed according to the Module Mounting Guideline. Failure to

comply may result in damage to modules or detached from the mounting system voiding

the warranty.

■

Module can be installed in both landscape and portrait modes.

■

For best performance, separate laying of positive and negative cables wherever possible.

Induced voltage surges in the DC main cable should be minimized by laying the positive

and negative cables as close together as possible.

•Where this is not possible or not desirable, the inverter energy system should

be connected to the distribution board located physically nearest to the inverter,

and the main switchboard. And main switch for the switchboard, to which the

inverter is connected, shall be a lockable switch.

■

The modules must be properly secured to their support so that they can withstand live load

conditions, including wind uplift, to the pressure they have been certified for. It is the

installer's responsibility to ensure that the clamps used to secure the modules are strong

enough.
