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℃.
In order to make use of the power generated on the back side of the double-sided photovoltaic
module, the back side barrier should be avoided.
Double-sided PV modules are not recommended to be installed in building attached PV
systems (such as BAPVs) because the back side of the modules generates electricity by absorbing
reflected light from the surface or scattered light from the surrounding environment.
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. Condensation or moisture can also be dissipated at the same 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.
