The roofs of many industrial and commercial buildings are not compatible with conventional solar photovoltaic panels, which, with their supporting structures, weigh 15 kg/m2. A Heliup innovation reduces PV panel weight by more than 60% without sacrificing profitability. The electricity generated can be used by the building or fed back into the grid for income.

The reduced weight is made possible by ultra-thin glass that provides both mechanical and physicochemical protection for the PV cells. This innovation is protected by three CEA patents for which Heliup holds exclusive licenses. This innovative technology has obtained the various levels of certification essential for its application.

The startup has invested in a 100 MWp/year production line, and already brings to market the product which is installed with success on several commercial, logistic and industrial buildings with low bearing capacity. The company has signed a collaboration agreement with the CEA to further improve the panel's performance.
