4.3 Alignment
If possible, all modules should be aligned in the same way.
The solar modules are suitable for installation both with their long side up and their short side up.
(see 5. Mechanical installation).
The modules are to be mounted in such a way that melt- and rainwater can run off freely and that
the module will not be constantly wet.
To increase the yield of the rear side of bifacial modules, shading by the substructure should be
avoided as far as possible. A substrate with a high albedo and an increased distance between the
module and the substrate also have a positive effect on the energy yield of bifacial modules.
Tilt angle
The solar modules must be installed at an angle of at least 10° to the ground. Building regulations
must be observed (in Germany maximum 75°).
Depending on the angle of inclination, the solar modules provide a different yield. The optimal tilt
angle depends on the location and the azimuth of the solar modules.
For optimal output the PV-Module should be facing North in the southern hemisphere.
All solar modules connected in series should be oriented the same way for optimal energy yield.
