Raising the panels relative to the roof surface
It is necessary to ensure that the size of the hydraulic connections corresponds to the distance allocated by the laying
system, between the surface of the roof and the lower edge of the module frame, which will be in contact with the
mounting system.
Depending on the hydraulic nominal flow, two types of fittings have been designed. Their size at the rear of the module
is shown below.
Figure 9 : Overall dimensions of hydraulic connections on the rear panel
The bulk of the hydraulic fittings on the rear side of the DualSun Spring panels is to be considered
carefully to avoid contact of the fittings with the surface of the roof cover.
Tie the interpanel links to the modules or to the rails of the mounting system in order to avoid them to
lay on the roof cover.
Please compare the following characteristics of the flexible hoses of the interpanel links with the allowable height:
