Mechanical
A structural analysis of the roofing structure has to be conducted before installation.
3.4
Module Orientation and Shading
In general, the modules can be mounted either in portrait or in landscape mode, depending on
different limiting factors:
Casting shadow on the panels should be avoided.
Always install the Flisom eFlex Series modules in a location that has good sun exposure
throughout the year. Less power is generated in shaded locations.
Plan the installation in such a way, that the Flisom eFlex Series modules receive the same
amount of direct sunlight within the same string (taking in account their orientation and
shadowing).
If direct shadow on active surface could not be avoided:
Orientation of the shadow on the active surface is crucial: the panel may only be installed as in
fig 2 (Parallel shade). To compare, fig 3 shows a series shade - shading the complete length
of several full cells. This type of casting shadow will negatively affect the power generation of
the module and can cause degradation by overheating.
Negative impact on the system performance from full or partial shading from
rooftop equipment, structural elements of a building and nearby trees, poles power lines or nearby
buildings should be avoided. A professional shading analysis prior to installation is recommended by
Flisom.
