Installation inclination refers to the Angle between the solar photovoltaic module
and the ground plane, as shown in Figure 7-1.

7.3. Installation requirements for bifacial module
Under the certain installation conditions, the backside of bifacial dual glass module
will also generate electricity power after receiving the reflected light, which will
bring additional power generation gain to the power station system.
The shading on the module surface will affect the power generation much, the
module should be installed in the place where the module cannot be shadowed
totally (such as the shadow from building, chimney and tree etc.), and even the
partially shading (such as the dirt, snow and aerial wire etc.) should be avoided.
The generation gain is related to the ground reflectivity, the module installation
height to the ground, the array spacing and the shadow shading to the module
