Do not place heavy objects on the PV module; Do not place the module on a sharp surface.Do not collide or distort the edges of the components.
Do not connect the positive and negative anode cables of the same PV module together. Do not open the carton box before the PV modules arrive at the location, keep the packing box in a ventilated, dry environment. During the transportation, please refers to Chapter 4 – Storage and Transportation instructions. Any inappropriate handling and storage can result in breakage of glass or loss of electrical property, and consequently loss the use value of PV modules. Take carefully by installing PV modules. In any case, it is forbidden to lift the PV module by lifting the junction box or cable. At least two or more than two operators must hold the edges of the PV module with both hands. Do not try to dismantle the PV module or remove any nameplates or components of PV modules. Do not apply paint or other adhesives to PV module top surface. Do not damage or scratch the glass on front side and back side of PV module. Do not drill holes on the frame of PV module, which may reduce frame loading capacity and lead to frame corrosion and invalidation of the limited warranty provided for customers. Do not scratch anodized coating of aluminum alloy frame except for grounding connection. Scratch may lead to frame corrosion and reduce frame loading capacity and long-term reliability. Do not repair or modify the PV module on your own.

3.6 Fire safety
Please refer to local laws and regulations before installing any PV modules and observe their building fire safety requirements. Rooftop installations shall be placed over fire resistant roof coverings appropriate for this rating, and adequate ventilation shall be provided between the back glass and the mounting surface. The roof structure and PV module mounting method will affect the fire safety performance of the building. Inappropriate installation can lead to fire risks. To guarantee roof fire rating, the distance between PV module frame and roof surface must be greater than 10 cm. Please use the appropriate PV module accessories, e.g., fuses, circuit breakers and ground connectors, according to local laws and regulations. Please do not apply PV modules in where exposed inflammable gases are nearby.
04 Storage and Transportation Instructions
4.1 Considerations for PV Module Turnover and Handling
Upon arrival of the PV modules, please check whether the carton box is in good condition, and check whether the PV module type and quantity on the outer packaging are consistent with the delivery order. If anything ,wrong is observed, please contact AIKO logistics and sales staff immediately.
1. Crane unloading:
Crane operations require dedicated personnel to command and certified personnel to work; Before lifting the goods, conduct a visual inspection of the box and pallet, and check whether the lifting straps are firm and secure. When unloading PV modules by crane, please choose and use specialized tooling according to the weight and size of the pallet.The center of gravity of the module should be at the top of the box.Please adjust the position of the sling to keep the modules steady.
To ensure the safety of the PV module, wooden sticks, boards or other fixtures of the same width as the outer packing cases should be used on the upper part of the box to prevent the sling from squeezing the pallet and damaging the PV modules.
Please operate the spreader at a constant speed, when the lifting is close to the ground, place the box gently in a relatively flat ground.
Do not unload PV modules under the weather conditions of wind more than 6 class (in Beaufort scale).

General information / Storage and transportation instructions 07/08
2. Forklift unloading:
The loading dock should be as the same height as the underside of the carrier. Driving speed control 3km/h, forklift speed control 1km/h, to avoid emergency stop, rapid start, bumpy vibration, and sharp object collision with components. The height of the forklift shelf baffle should be 1200mm, and a buffer pad should be installed on the front arm of the forklift to avoid direct contact with the components; The maximum number of forks per shipment is 1 stack.
Forklift operators must hold professional operating certificates. If the packaging box obstructs the forklift driver’s line of sight it is recommended to reverse the forklift during transportation and arrange for a dedicated person to supervise and command to ensure that the forks do not exceed the components, preventing accidents that may cause personal injury or damage to components due to the dropping of packaging boxes. After transportation to the installation site, please choose a hard ground for placement as much as possible.
4.2 Considerations for PV Module Turnover and Transportation
When using a forklift to transport components, please ensure that the fork length of the forklift meets the requirements. It is recommended that the thickness of the forklift teeth be less than 80mm, and the length of the 3/4 pallet be less than the fork length and the pallet length. When forking, the fork should be tightly attached to the ground, and the distance between the forks should be adjusted to a suitable distance to avoid uneven force that may cause the components to tilt. During the transportation of components, the component pallets shall be placed closely, and the gap between the component packaging box and the front and rear of the vehicle and container shall be filled with foam to avoid collision and damage to the components. If using box trucks or other types of vehicles for transportation, please pay attention to using carriages with guardrails. The height of the guardrails should not be less than 2/3 of the height of the components, and fastening straps should be used to fix the components to the carriages. When the components are to be transported at the project site, the transportation route should be chosen on a smooth road surface to avoid damage or hidden cracks caused by bumps, collisions, squeezing, tilting, etc.
Before unpacking, conduct an external packaging inspection, use a utility knife to remove the packing tape, prohibit violent disassembly, and prohibit sharp objects from contacting the components. When opening the carton box, please place the PV modules to be unpacked at a distance of 20-30cm from the wall or another torr of PV modules, and then remove the torr. After removing the cable tie of the fixed PV modules, slowly lean the PV modules against the wall or another torr of PV modules to prevent them from falling.
Please handle the installation PV modules gently during transportation. Do not lift the PV modules by pulling the junction box or cables under any circumstances. Two or more people must hold the edges of the PV modules with both hands.

05 Installation Conditions
5.1 Location and working environment
The component is not suitable for the space environment. The component must be installed on a suitable ground or building and cannot be installed on any type of movable vehicle. PV modules are recommended to be installed in a -20 to 50 environments, with an extreme working ambient temperature of -40 to 85 and a humidity less than 85%RH. Do not install PV modules in locations or areas where there is a risk of flooding, and do not install or place PV modules near open flame or flammable materials. When installed at a distance of 50m to 500m away from the seashorewe recommended to use the Sirius module. Other modules are not supported for application in such scenarios. For rooftop installations, leave a safe working area between the edge of the roof and the external edge of the PV module array. For rooftop installations, check the roof loads and make a construction organization plan to meet the applicable standards. Ensure PV module is positioned to receive adequate sunlight and it is advised to avoid shading the PV module surfaces in part or in whole (by trees, buildings etc.).

5.2 Tilt angle selection
Tilt angle of PV module is the angle between the PV module and the horizontal ground. Different projects should choose different installation inclination angles according to local conditions.
All PV modules in the same array should be same orientation and angle. Different orientations and angles will result in different total solar irradiation absorbed by PV modules, leading to output mismatch that degrades system operating efficiency. In order to achieve the maximum annual generating capacity, the optimal orientation and inclination of PV modules in the installed area should be selected. When the surface of the PV module is perpendicular to sunlight, the output power reaches the maximum output value. AIKO recommend the installation angle should not less than 10°. The optimal tilt angle of PV arrays should be designed by taking into account the multi-year average monthly irradiance, direct irradiance, scattering irradiance, wind speed and other climate conditions at the location. PV modules should be tilted at an angle to receive the maximal annual irradiance. Angles shall be selected by considering natural conditions such as local wind load, snow load and avoidance of water and dust collection on module surfaces.
For details on the optimal tilt angle for installation, refer to consult a reliable local solar system installation company.
06 Mechanical Installation
6.1 General Requirements
Make sure that the PV modules are properly installed and the mounting structure are adequately fastened. PV module mounting system shall be constructed of anticorrosive, ultraviolet resistant materials. Installation bracket system shall be tested and inspected by the third-party testing institution with static mechanical analysis capacity in accordance with local national standards or international standards. In regions with heavy snowfall in winter, adjust the height of the mounting system so that the lower edge of the PV module is not covered by snow. In addition, ensure the lower part of PV module is not in the shadow of plants, trees. For rooftop installations, the minimum gap between the PV module frame and the roof shall be 10cm which is good for air circulation to achieve better performance of PV module. The module frames can encounter thermal expansion and cold contraction. There will be a certain amount of bending deformation at different temperatures, which will not affect the performance and reliability of the module. The minimum mounting distance between adjacent PV modules is 10mm. If there are special requirements, please contact AIKO for more details on installation methods. The minimum mounting distance between adjacent PV modules is 10 mm. Make sure that backside of PV modules will not be in contact with bracket or building structures that can pierce into the inside of the PV modules, especially when the PV module surface is imposed by pressure.

Installation conditions / Mechanical Installation 11/12
Maximum static load of the PV module is downforce 5400 Pa and uplift force 2400 Pa, which can vary from different mounting methods of the modules (please refer to the following installation guidance), the described load in this manual is for the test load. The PV module loads described herein are test values. According to IEC 61215-2021 installation requirements, when computing the corresponding maximum design load, it is necessary to divide by at least 1.5 times the safely factor in conmpliance with the local laws or regulations. In additions, project design loads must be based on project location, climate, mounting structure and applicable standards. Design loads are determined by bracket suppliers and professional engineering and technical personnel. please observe both the local laws and regulations and the instructions of structural engineers.
6.2 Mechanical Installation of PV Modules
PV modules can be connected to the racking system using pressure clamps and bolts. PV Modules must be mounted as recommended and illustrated below. Other mounting configurations may be used provided that consultation is made with, and prior written consent is received from AIKO. Failure to do so will invalidate our warranty.
6.2.1 PV Module Installation Method: Mounting pressure Clamps
Specialized pressure clamps are used to mount modules as shown below.

Under no circumstances should the clamp touch the glass or deform the frame.
Be sure to avoid shadowing effect from the pressure clamp.
When installing the modules, be cautious not to block the drain hole of the frame.
Pay attention to the matching of the height of the frame with the pressure clamp.
Be sure that pressure clamps will not fail due to deformation or corrosion while the entire PV module is under load. Pressure clamps of material 6005-T6 are recommended. The length should be 50mm and the thickness should be 4mm. The overlapped distance between the pressure clamps and the module frame should be at least 10mm, but no more than 12mm.
Clamp positions are of crucial importance for the reliability of the installation. The clamp centerlines must only be positioned within the ranges indicated in table below, depending on the configuration and load.

When choosing clamp-mounting, please be sure to use at least four clamps on each PV module. Depending on the local wind and snow loads, if excessive pressure load is expected, at least six clamps should be required to ensure the PV module can bear the load (more details, please contact AIKO technical personnel).
Do not drill additional holes or modify the PV module frame. Doing so will void the PV module’ s warranty.
Use appropriate corrosion-proof fastening materials. All mounting hardware (bolts, spring washers, flat washers, nuts) should be hot dip galvanized or stainless steel. Install and tighten the PV module clamps to the mounting rails using the torque stated by the mounting hardware manufacturer.
M8 bolt tightening torques must be within 16~20Nm and M6 bolt tightening torques must be within 8~12Nm, respectively depending on bolt classes. For the bolt grade, the technical guidelines from the fastener suppliers should be followed. Different recommendations from specific clamping hardware suppliers should prevail.
6.2.2 PV Module Installation Method: Bolts Mounting
Using bolts to secure the PV module on the bracket through the mounting holes at the back of PV module’ s frame. PV modules come standard with 4 or 8 mounting holes, matching M8 or M6 bolts, as figure below:

7.1 Electrical performance
There are tolerances (±3 between the rated values of the electrical performance under STC and measured values. Including Isc, Voc and Pmax under STC (1000 W/m2 Irradiance, a cell temperature of 25 and an AM1.5). When PV modules are in series connection, the string voltage is sum of every individual PV module in one string. When PV modules are in parallel connection, the current is sum of the individual PV modules as shown in below. PV modules with different electric performance models cannot be connected in the same string.

Series connection
Overcurrent protective device Diode Connector

Parallel after series connection

If the PV module is passed through by a reverse current greater than the maximum fuse current of the PV module, the PV module shall be protected with an over current protector of the same specification. If more than two strings are connected in parallel, each PV module string shall be protected with an over current protector as shown above.
The string voltage must not exceed the maximum voltage that the system can withstand or the maximum input power of the inverter or other electrical devices installed in the system. To ensure this, the open circuit voltage of the array shall be calculated at the minimum expected ambient temperature at that location. The following formula may be used:

Where: N Voc Tmin

Maximum system voltage N×Voc×[1+*(Tmin-25)] number of modules connected in series open circuit voltage of each module (refer to product nameplate or specification) [V] temperature coefficient of open circuit voltage for the PV module (refer to the specification) [°C-1] lowest ambient temperature [°C]

7.2 Cables and Connections
PV module’s junction boxes with the lP68 protective level and composed of connected cables and IP68 connectors. The PV module has a positive and a negative PV connector connected into the junction box and a plug-and-play connector connected at the other end, Using the positive connector of the module to connect the negative connector of the adiacent module connects the two modules in series. Use specialized solar cables and appropriate connectors according to local electrical and installation standards, codes and regulations at the location, and ensure that the electrical and mechanical properties of the cables are good. Electrical connections shall comply with local electrical requlations AlKO PV modules use specialized PV cables which have a cross sectional area of 4 mm2 and are ultraviolet resistant. AlKO recommends that all cables are run in appropriate conduits and sited away from areas prone to water collection, AlKO recommend use copper cables with a minimum cross sectional area of 4mm2 which are rated for 90 and are UV resistant shall be used as PV connecting lines. The minimum bending radius of the cable is 43mm.
7.3 Connector
Take care to keep the connectors dry and clean. Make sure that the connector nuts are tightened before making any connection. Do not connect while the connectors are wet or otherwise abnormal. As connectors provide IP68 protection only when the positive and negative poles are fully mated, please connect PV modules as soon as possible after installation or take proper steps to prevent water vapor and dust from coming into the connector. Avoid exposing the connector to direct sunlight and water. Avoid exposing the connector directly to ground surface or roof. Make sure that all electrical connections are secure. Incorrect connection can result in electrical arcing and shocks. If you need to use the connection of different types of connectors,please contact AIKO customer service(cs@aikosolar.com)

08 Grounding
PV modules are designed with an anodized anticorrosive aluminum alloy frame as a rigid support. PV module frames must be grounded to ensure safe use and protect the PV module against lightning and electrostatic damage. Grounding must be made with the grounding device in full contact with the interior of the aluminum alloy and penetrating the oxide film on the frame surface.
Grounding devices include grounding screws, flat washers, puncture gaskets and grounding wires. All these items shall be constructed of stainless steel except grounding wires. Grounding conductors or wires shall be copper wires. Grounding conductors shall be connected to the ground through an appropriate grounding electrode. Third-party grounding devices meeting local electrical installation standards at the location may be used for grounding AIKO PV modules. Grounding device shall be installed according to the operation manual provided by the manufacturer.

Following is the recommended grounding method:
There are 4.2 mm grounding holes on surface C of the PV module frame. Use a separate grounding wire and accessories to connect the aluminum alloy frame of PV modules and connect the grounding wire to the ground. We recommend using M4×12 mm grounding bolts accompanied by M4 nuts, star washers and flat washers.

We recommend torquing grounding bolts to 3~7 Nm and using 4 mm2 copper wires as grounding wires.

Unused PV module mounting holes on the frame may also be used for grounding purposes.

Connection mode: The star washer, flat washer, and ground wire are placed in sequence, threaded through the ground hole using screws, and tightened to secure the adjacent PV modules.

Grounding/Maintenance of PV modules 23/24

09 Maintenance of PV modules
PV modules shall be inspected and maintained on a regular basis, especially within the warranty period, which is an obligatory responsibility of the user. Any damage or other visible abnormalities of the PV module shall be reported to AIKO customer service(cs@aikosolar.com) upon discovery.
9.1 Cleaning
The power output of PV modules is related to incident light intensity and can be reduced by dust collection or other shadings. Dirt on PV modules must be cleaned up immediately. The cleaning frequency depends on the degree of dirt collection. PV modules installed at an adequate tilt angle will allow rainwater to clean the PV module surfaces, thereby reducing the cleaning frequency. We recommend cleaning the glass surface of the PV module with a clear water-netted sponge. Do not clean PV modules with a detergent containing acid or alkali. Do not clean PV modules with a hair brush or other rough surface tools. We recommend cleaning PV modules in the early morning or late afternoon or other periods of time when the light is weak and the PV module temperature is comparatively lower.

Method A: High Pressure Water Cleaning
Water quality requirement
PH:6-8 Water hardness – calcium carbonate concentration: <600mg/L; Recommended use of soft water cleaning; Recommended maximum water pressure is 4MPa(40bar)

Water

Absolute ethtl alcohol

Method B: Wet Test Cleaning

If there is too much stain on the surface of the PV module, it’ s recommended to carefully use an insulating brush, sponge or other soft cleaning tool.

Dust-free gloves

Dust-free paper

Ensure that any brushes or agitating tools are made of insulating material to minimize the risk of electric shock and that they do not scratch the glass or aluminum frame.

For oil stains, it’ s recommended to use an environmentally friendly,non-corrosive cleaning cleaner.

Method C: Robot Cleaning
If the cleaning robot is used for dry cleaning, the brush material is required to be soft plastic, so that the glass surface and aluminum alloy frame of the PV module will not be scratched during and after cleaning. The weight of the cleaning robot should not be more than 40kg, the PV module damage and power degradation caused by improper cleaning with the cleaning robot are not covered by the warranty of AIKO.
9.2 Visual Checks of the PV Modules
Visually checks for visual defects on modules, such as: Whether the PV module glass is broken Whether the junction box is damaged or the cable is broken Whether the PV module is shaded by foreign matter or shadows Check whether the bolts fixing the PV module to the racking are loose or corroded and adjust or replace them if necessary Check whether the PV modules are well-grounded

Maintenance of PV modules 25/26
9.3 Checks of Connectors and Cables
It is recommended to perform preventive examinations every six months, such as: Whether the connectors are properly sealed and the cables are properly fastened Whether the sealant of the junction box is cracked
9.4 AIKO Technical Support
In order to request Technical Support: Collect evidences of the issue as (a) photos and (b) measurements. Be prepared to show the purchase invoice and module serial number. Contact your Installer.
