The most important technological innovation is the integration of the solar modules as part of the substructure, resulting in a solid unit: the arch, statically stable and inexpensive to construct. Secondly, the slidable nature of the modular arc opens up different possibilities for the use of the system and also improves the installation. Third, MarcS uses module and floor space more efficiently than other traditional options. A new solution that cannot be compared to an existing PV system.
