The problem:
The back foil of the installed modules dissolved and became permeable. The penetrating moisture caused short circuits, which led to inverter failures and caused high yield losses.

The challenge:
In order to carry out the revamping project as economically as possible, only the modules were to be replaced. Since the substructure is a slide-in system, the dimensions of the new modules could only deviate minimally. The matching module series is no longer manufactured.

The solution:
There are two manufacturers whose modules are compatible with the substructure system when special adapters are used. In addition, since the new modules are more efficient than the old ones, the required area is reduced by about one third - with the same rated power. New areas are created, e.g. for the production of even more solar energy!
