The installation method is very important for the mechanical load. Failure to follow
the installation of this manual will result in different snow pressure and wind pressure
load capacity.
The system builder needs to ensure that the installation is in accordance with local
laws and regulations.

Site Selection
◇
In north latitude area it is best to face south for the module, while in south latitude
area, it is best to face north. It is best that the front of the module is perpendicular to
the direction of the midday sun light.
◇
The module is recommended to be installed at an optimum angle of inclination for
maximum capture of sunlight. According to the right hand helical law, basically the
same latitude as the installation site, facing the equator. The design must be based
on local conditions
and
choose the best inclination.
◇
When installing solar modules on the roof, be sure to maintain a safe working area
between the edge of the roof and the solar arrays. There must be a certain safety
distance between arrays of large power stations in order to facilitate the cleaning,
inspection, and maintenance of the modules inside the array.
◇
The modules can be installed horizontally or vertically, but the horizontal
installation method can minimize the shading effect of dust on the solar panels.
When installing, choose a location where the sunlight can be fully illuminated and
ensure that it cannot be blocked at any time.
◇
The modules can not be used in the vicinity of the equipment or place where the
flammable gas is generated or stored.
◇
The modules can not be installed in the environmental area where module defects
are caused by various chemical reactions, such as acid rain, alkaline gas, salt mist,
etc.
◇
The modules can not be installed in the environmental area that exceeds the
maximum system voltage of the modules, such as high-voltage power lines. The
module’s position should be maintained at a safe distance from the high-voltage
power while the safe distance is determined by the high voltage level.
◇
If the modules are to be installed on the floor of a dwelling, local regulations such
as fences should be complied with (the fences should be kept at a certain distance
from the array to avoid shading impact of the fence on the array).
