Aiko Neostar 2P 480W - Installation Manual

4. Installation conditions 

4.1 Installation site and working environment 

AIKO PV modules are recommended to be installed in an environment where the operating ambient temperature is -20 ° C ~ 50 ° C. the limiting operating ambient temperature of PV modules is -40 ° C ~ 85 ° C and the humidity is lower than 85%rh. 

AIKO PV modules are applicable to the operating environment below 2000m above sea level. 

Do not directly irradiate the artificial spotlight on the solar PV module. 

When installing solar PV modules on the roof, a safe working area must be reserved between the edge of the roof and the outer edge of the PV module array. 

When photovoltaic modules are stacked on the roof, the load of the roof shall be rechecked and the construction organization plan meeting the specification requirements shall be formulated. 

When selecting the installation position of PV modules, the position where the sun can fully shine shall be selected to avoid partial or total shielding (trees, buildings, clothes, tools, packaging materials and other obstacles) on the surface of PV modules. 

A safety factor (1.25) regarding the open circuit voltage (Voc) and short circuit current (Isc) needs to be set, considering that the irradiance of the installation site can sometimes be higher than 1000W/m² and the temperature may be lower than 25℃. 

The PV module shall be installed in a well ventilated position to ensure sufficient air circulation at the back and side of the PV module, so that the heat generated during the working state of the PV module can be dissipated in time. 

When used in areas with high wind pressure and snow pressure, the support and fixed structure shall be designed in strict accordance with local design codes to ensure that the external load does not exceed the mechanical strength limit that the PV module can withstand. 

In salt spray, sulfide and ammonia environments (coastal, factory, volcanic and farm), corrosion may occur at the connection between modules and supports, or at the position where the grounding is connected. 

Corrosion resistant materials (stainless steel or aluminum materials, etc.) must be used to contact the PV module, and the installation position shall be subject to anti-corrosion treatment.

5. Mechanical installation 

5.1 General requirements 

Ensure that the PV module installation method and support system are firm enough. The PV module mounting bracket must be made of corrosion-resistant and UV resistant materials. 

The PV module must be firmly fixed to the bracket. 

In areas with heavy snowfall, a higher support system shall be selected to avoid the lowest point of PV module being covered by snow for a long time. The lowest point of the PV module shall be at a certain height to prevent the PV module from being covered by weeds and trees on the ground. 

When the PV module is installed parallel to the roof, the minimum gap between the PV module frame and the roof is 10cm. 

The minimum installation distance between two adjacent PV modules is 10mm. 

The maximum static test load passed by the PV module is front 3600/ back 1600 with Safety factor 1.5. 

The specific load depends on the installation mode of the PV module (please refer to the following). All load values mentioned in this manual are static test loads. Note: according to IEC 61215-2, 1.5 times of safety factor shall be considered when calculating the maximum design load; When calculating the wind load, the design maximum instantaneous gust load shall consider 3 times the safety factor. 

The loads of the modules described in this manual are test loads. According to the installation requirements of IEC 61215-2, the corresponding maximum design load should be divided by at least with safety factor 1.5. The design load of the project needs to depend on the project location, climate, support structure, and relevant specifications. The support supplier and professional engineers are responsible for determining the design load, in accordance with local laws and regulations and the instructions of the structural engineer. 

5.2 Mechanical installation 

The connection between AIKO single glass photovoltaic modules and the support system can be installed by pressing blocks. PV modules must be installed according to the following suggestions and examples. If there are other installation methods, please consult Shenzhen AIKO digital energy in advance and obtain written consent, otherwise the warranty will be invalid.
