1. Introduction

Perlight Solar modules consist of a series of electrically interconnected crystalline silicon

solar cells, which are permanently encapsulated between a tempered glass superstrate and

substrate. The entire laminate is secured within an anodized aluminium frame for structural

strength; ease of installation and to protect the cells from the most severe environmental

conditions.

Perlight Solar modules are a highly reliable, virtually maintenance-free direct current (DC)

power source, designed to operate efficiently in sunlight. Perlight Solar modules are ideal for

all applications, Residential, Commercial and Utility-Scale. Perlight Solar modules may also

be used to power remote homes, recreational vehicles, water pumps, telecommunication

systems and many other applications either with or without the use of storage batteries.

Please read this manual carefully prior to handling and installation.

Installation and maintenance of Perlight Solar modules may only be carried out by trained and

qualified personnel.

If you require further information, contact your supplier or local Perlight Service Centre.

Please provide a copy of this manual to the owner and operator of the PV system for

reference.

Thank you for choosing Perlight Solar PV modules.

4. Warning and Notes

Perlight Solar modules generate electricity when exposed to light. An array

of modules can cause lethal shock and burn hazards. Only authorized and

trained personnel should have access to the PV modules. To reduce the risk

of electrical shock or burns, modules may be covered with an opaque material

during installation. Do not touch live terminals with bare hands. Use insulated

tools for electrical connections.

Each Perlight Solar module has a pair of male and female waterproof connectors. For a series

electrical connection, connect positive (+) connector of first solar module to negative (-)

connector of the following module.

Do not short the positive and the negative. Do not disconnect under load. Ensure each

connection is sound with no gap between the insulators. Poor connections may cause arcing

and pose a fire and/or an electrical shock hazard.

Artificially concentrated sunlight shall not be directed on the Perlight Solar module. The

electrical characteristics are the indicated value of Pmax under standard test conditions

(Irradiance of 1000W/m², AM 1.5 spectrum, and cell temperature of 25°C).

Under normal conditions, a solar PV module is likely to experience conditions that produce

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

value 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 sizes

of controls connected to the Perlight Solar PV module output. Refer to local and national

Electrical Code for any additional multiplying factors, which may also be applicable.

Handle with care

Unpack and handle the PV modules with care. For safety always avoid installing PV modules

during wet and windy conditions or during electrical storms.

• Do not place heavy objects on to the PV modules.

• Do not step or walk on the module, although Perlight Solar modules are rugged, flexing

caused by bodyweight on the module face can create micro-cracks in the solar cells,

which may not be visible but will effect cell performance as the module ages. Take care

not to impact the module during installation, module glass can be broken (and the module

will no longer work properly) if it is dropped or hit by tools or other objects.

• Take care not to allow the front glass or backsheet of the module come into contact with

hard or sharp surfaces such as scaffold during the installation process to avoid scratching

or damaging the PV module.

• Do not scratch the PV module backsheet.

• Do not drill or cut the PV module frame.

• Do not apply paint or glue to the PV module.

5. Permit

Before installing your system, contact local authorities to determine the necessary permit,

installation and inspection requirements.

6. Climate Conditions

Install the Perlight Solar PV modules in the following conditions:

• Ambient temperature: -20°C to +40°C.

• Operating temperature: -40°C to +85°C.

• Storage temperature: -40°C to +40°C

• Humidity: below 85RH%

• Wind pressure: below 50.12lb / ft² (2400Pa)

• Corrosion resistant: Except for corrosive salt areas and sulphurous areas.

8. Site Selection

In most applications, Perlight Solar modules should be installed in a location where they

will receive maximum sunlight throughout the year. In the Northern Hemisphere, the

module should typically face south, and in the Southern Hemisphere, the modules should

typically face north. Modules facing 30 degrees away from true South (or North) will lose

approximately 10 to 15 per cent of their power output. If the module faces 60 degrees away

from true South (or North), the power loss will be 20 to 30 percent.

When choosing a site, avoid trees, buildings or obstructions, which could cast shadows on

the solar photovoltaic modules especially during the winter months when the arc of the sun is

lowest over the horizon. Shading causes loss of output, even though the factory fitted bypass

diodes of the Perlight Solar module will minimize any such loss.

Do not install the Perlight Solar module near naked flame or flammable materials. Do not

install the Perlight Solar module in a location where it would be immersed in water or

continually exposed to water from a sprinkler or fountain etc.

9. Module Tilt Angle

Perlight Solar modules connected in series should be installed at same orientation and angle.

Different orientation or angle may cause loss of output power due to difference in amount of

sunlight exposed to the module.

Perlight Solar modules produce the most power when they are pointed directly at the sun.

For installations where the Perlight Solar modules are attached to a permanent structure,

the modules should be tilted for optimum winter performance. As a rule, if the system power

production is adequate in winter, it will be satisfactory during the rest of the year. The module

tilt angle is measured between the solar modules and the ground (Figure 2). Optimal tilting of

Perlight Solar module is almost the same as the latitude of installation location.

10. Mounting and Notes

The PV module frame is made of anodized aluminium, and therefore corrosion can occur if

the module is subjected to a salt water environment with contact to a rack of another type

of metal (Electrolysis Corrosion). If required, PVC, EPDM or stainless steel washers can be

placed between the PV module frame and support structure to prevent this type of corrosion.

Module support structures that are to be used to support Perlight Solar modules at the

correct tilt angles should be wind and snow load rated for use by the appropriate local and

civil codes prior to installation.

Perlight Solar modules can be mounted using the following methods:

•

Direct Fixing to Mounting Structure

The frame of each module has 8 mounting holes

(14mm*9mm), which can be used to secure the

modules to a supporting structure. The module frame

must be attached to a supporting structure using

corrosion-proof M8 stainless steel nuts and bolts with

spring washers and flat washers in at least four points

symmetrical on the PV module. Applied torque is

approx. 8 Newton-meters.

modify the module frame under any circumstances. Recommended distance between two

modules is 5mm considering linear thermal expansion of the module frames.

Clearance between the module frame and mounting surface may be required to prevent the

junction box from touching the surface, and to circulate cooling air around the back of the

module.

Mounting design may have an impact on fire resistance. If the modules are to be installed on

the roof or wall of a building, using an integrated mounting system, the fire resistance of roof

covering or wall should be rated for the application and certified for use to local and national

standards. Here the stand-off method or the rack method is recommended. The modules are

supported parallel to the surface of the building wall or roof. Clearance between the module

frames and surface of the wall or roof is required to prevent wiring damage and to allow air

to circulate behind the module. The recommended stand-off height is 115mm. Any slope less

than 5in/ft (127mm/305mm) is required to maintain a fire class rating. Do not mount Perlight

Solar module in such way that the drain holes of the module are intended to block up.

Roof-integrated (in-roof) systems must comply with local and national regulations, including

fire test certification where necessary.

11. Grounding

All module frames and mounting racks must be properly grounded in accordance with local

and national electrical regulations. Proper grounding is achieved by connecting the module

frame(s) and structural members continuously one to another using a suitable grounding

conductor. The grounding conductor or strap may be copper, copper alloy, or other material

acceptable for use as an electrical conductor as per local and national guidelines. The

grounding conductor must then make a connection to earth using a suitable earth ground

electrode.

Attach a separate conductor to one of the marked 4mm diameter grounding holes on the

module frame with a bolt and nut that incorporates an external tooth washer. This is to ensure

positive electrical contact with the frame.

The rack must also be grounded unless they are mechanically connected by nuts and bolts to

the grounded Perlight Solar modules. The array frame shall be grounded in accordance with

local and national guidelines.

12. Module Wiring

Each solar module is wired with three separate series cell strings.

Bypass Diodes

Bypass diodes are wired in parallel with the series cell strings to prevent hot spot heating

caused by individual cell reverse bias that occurs when a module is partially shaded.

Output Cables

Each module has two standard 90°C rated, water-proof, UV resistant output cables each

terminated with plug & play connectors. This cable is suitable for applications where wiring is

exposed to the direct rays of the Sun.

Field connections

Connecting cables should be a minimum of 12 AWG copper cables, which are UV resistant

and insulated for a minimum of 90°C. All wiring and electrical connections must comply with

local and national Electrical Code.

Blocking Diodes

In a system utilizing a battery, blocking diodes are typically placed between the battery

and the solar module output to prevent battery discharge at night. Diodes that are used as

blocking diodes must: Have a Rated Average Forward Current [IF(AV)] above maximum

system current at highest module operating temperature. Have a Rated Repetitive Peak

Reverse Voltage [VRRM] above maximum system voltage at lowest module operating

temperature.

13. Maintenance

Cleaning

Under most weather conditions, normal rainfall is sufficient to keep the Perlight Solar module

glass surface clean. If dirt build-up becomes excessive, clean the glass only with a soft cloth

using mild detergent and water. USE CAUTION WHEN CLEANING THE BACK SURFACE

OF THE MODULE TO AVOID PENETRATING THE SUBSTRATE MATERIALS. Solar Modules

that are mounted flat (0° tilt angle) should be cleaned more often, as they will not ‘’self clean’’

as effectively as modules mounted at a 15° tilt or greater. Perlight recommend cleaning the

modules during the early morning or evening, when the panels will be operating at a lower

temperature and producing little energy.

• Do not lean or stand on the modules during cleaning.

• Do not use high pressure water jets to clean the solar modules.

Annual Checks

Once a year, check the tightness of terminal screws and the general condition of the wiring.

Also, check to ensure the mounting hardware is tight and secure. Loose connections will

result in damage to the array.

Changed Perlight Solar modules must be of the same kind and type. Do not touch live parts

of cables and connectors. Use appropriate safety equipment when working (insulated tools,

insulating gloves, etc.).

Only trained personnel may carry-out repair work to the PV modules and

system components.

Cover the front surface of the solar module with an opaque or other material

when working on the modules. Solar modules generate high voltage when

exposed to sunlight.

14. Recycling

Perlight work to avoid unnecessary waste, keeping module packaging to a minimum, while

maintaining the protection of the modules during transport.

Please recycle the cardboard and paper packaging in accordance with local guidelines and

regulations.

End of Life Disposal and Recycling

Perlight solar modules are designed to produce electricity for a minimum of 25

years, however the panels may continue to offer useful energy for years to come

after this point. Once the panels reach the end of their useful life, they should be

recycled in accordance with local guidelines and regulations.

Within the European Union, solar modules are subject to Waste Electrical and

Electronic Equipment (WEEE) regulations. The WEEE symbol is displayed on

every module nameplate label at the rear of the panel. This means that this

Fig.11: WEEE Symbol

product shall not be treated as household waste and must be disposed of

at an appropriate collection point.
