5 Module Installation
Installation environment
The module is recommended to be installed in an environment where the operating temperature ranges from -20°C to 50°C.
The maximum operating temperature ranges from -40°C to 85°C, and the humidity is lower than 85%RH.
When installing solar modules on a roof, it is also necessary to leave a safe working area between the edge of the roof and the
outer edge of the photovoltaic module array.
When modules are piled on the roof, the load of the roof should be rechecked, and the construction organization plan in
accordance with the requirements of the code should be formulated.
If in the northern hemisphere, usually choose the light facing south installation of the module. If you are in the southern
hemisphere, you usually choose the light-facing north mounting of the module.
when selecting module installation position, should choose can make full sunlight position, to avoid the module surface forms
part or all of the shade (trees, buildings, clothing, tools, packing materials and other obstacles), because these objects on the
module form the shadow, the shadow will cause loss of output power.
The module should be installed in a well-ventilated place to ensure adequate air circulation on the back and side of the module
to facilitate the timely release of heat generated when the module is working.
When used in areas with high wind pressure and snow pressure, support fixed structures should be designed in strict
accordance with local design specifications to ensure that the external load does not exceed the mechanical strength limit that
the modules can bear.
At a place 50m to 500m away from the sea, corrosion may occur at the part where the frame of the module is connected to the
support, or the part where the grounding is connected. Stainless steel or aluminum materials must be used to contact the
photovoltaic module, and the installation part must be treated with anti-corrosion.
Please consult the Hyundai Energy Solution technical support department for more information on the use of modules in special
climates, such as an altitude greater than 2000m, heavy snow, severe hail storm, hurricane, etc.
Inclination Choice
The inclination Angle of the photovoltaic module refers to the included Angle between the photovoltaic module and the horizontal
ground. Different projects choose different installation inclination Angle according to local conditions.
Modules connected in series of the same array must be in the same direction and Angle. Different installation directions and angles
cause differences in the total amount of solar radiation absorbed by modules, resulting in a loss of output power, which reduces the
operating efficiency of the system.
The maximum power is generated when the sunlight directly exposure to the modules. Consider the power output of the module
in winter when selecting the best installation Angle.
In order to facilitate module cleaning and wash away dust on module surface when it rains, for detailed installation Angle, please
follow the advice given by experienced PV module installers.
