Installation Manual

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.

Dimensions: 1646114030mm

Warning and Notes

Warning 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.

Permit

Before installing your system, contact local authorities to determine the necessary permit, installation and inspection requirements.

Climate Conditions

Install the Perlight Solar PV modules in the following conditions:

• Ambient temperature: -20°C to +45°C.
• Operating temperature: -40°C to +85°C.
• Storage temperature: -40°C to +°C
• Humidity: below 85RH%
• Corrosion resistant: Except for corrosive salt areas and sulphurous areas.

Mechanical Load Bearing Capacity

The modules have passed the mechanical load test of wind pressure of 2400Pa and snow pressure of 5400Pa; at the same time, they have passed the mechanical load test of wind pressure of 3600Pa and snow pressure of 3600Pa.
Note: The module mechanical load is based on the installation method and installation site. Calculation of mechanical load must be carried out by a professional installer according to the system design requirements.

Identification

Each PV module is affixed with two kinds of labels, providing the following information:

1. Label: Describes the product name, PV module model, nominal power, rated voltage, rated current, open circuit voltage, short circuit current, maximum system voltage, PV module size and weight under standard test conditions.
2. Serial number: Each module has a unique bar code number, each bar code number has 20 letters and numbers. The bar code is permanently encapsulated inside the module, as can be seen clearly from the top right corner of the module. The bar code number allows you to trace information about the module production process.

Module Structure

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.

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.

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
• Suitable module clamps as part of solar mounting system
• Insertion systems
• Roof integrated systems

| 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. 16 Newton- meters.

Module mounting clamps must not come into contact with the front glass and must not deform the frame. Module clamps should not cause shadowing effects. It is not permitted to 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.

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.

Module Wiring

Each solar module is wired with two 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.

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.
• Do not use rough surface materials to clean the modules.
• Do not use acid or alkali cleaning fluids.
• Do not attempt to clean modules if front glass is damaged or if there are any signs of exposed electrical wiring, which pose an electric shock hazard.

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.

Warning 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.

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.

Fig.11: WEEE Symbol 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 product shall not be treated as household waste and must be disposed of at an appropriate collection point.
