5.2.3 Description of the installation position
The low/normal level of load condition is applicable to the installation in most of environmental conditions:
the maximum static load on the back of the Modules is 2400 Pa (i.e. wind load), and the maximum static
load on the front of the Modules is 2400 Pa (i.e. wind and snow load).
The high level of load condition is applicable to the installation in harsher environmental conditions such as
storm, heavy snow, etc: the maximum static load on the back of the Modules is 2400 Pa (i.e. wind load) and
the maximum static load on the front of the Modules is 5400 Pa (i.e. wind and snow load), depending on the
pressure level that it would endure according to IEC standard.
For the dynamic loads, such as wind, the safety factor needs to be increased by 3 times. It means that the
maximum dynamic load is 800 Pa when the wind speed is less than 130 km/h.
