A beautiful photovoltaic system installed by our customer Elettric System Srl on a flat industrial warehouse, particularly suitable for hosting the Sun Ballast as a structure for photovoltaic panels. In this case the choice fell on the ballasts of Connect system which do not need to be fixed on the roof. Despite this, they are extremely resistant to the actions of the wind because the rows are linked together forming a single lattice. The system also has the characteristic of being very light by limiting the load on the roof which is however calculated by our technical office free of charge together with the technical report.
