The problem results more severe in the case where the barrier result to be destined where there is no electrical line. In this case it is necessary to have the installation of plants and the realization of the entire power line at the same time of the assemblage of the barrier, the whole with clear additional costs and time of realization.

  • the positioning of the panels is indeed unavoidably influenced by the variation of the alignment of the route along which it is built the barrier, determining these continuing angle variation that are hardly settable and predictable. It is then clear how in such case it is hard to use the entire paneling with the highest efficiency, causing an insufficient and not reliable power supply to the light plants.
  • a further problem refers to the light reflection, phenomenon that is common to all the vitreous bodies with reflecting nature.
