The Bigfoot ballast system is developed for optimise installation operations thanks to a integrated functional geometry, also designed for the’packaging optimisation. The system provides pre-drilled holes for the installation of accessories without the need to drill into the item, threaded bushings embedded in steel within the ballast for fixing the clamps. All these features contribute to reduce installation time and overall installation costs compared to traditional ballasted systems. The system is suitable for installations where required durability and reliability, also in harsh environmental conditions. The correct sizing of ballast systems must be defined according to the installation conditions, of the wind zone, of the’orography of the territory, of the’height of the building and the stability checks required by the technical regulations in force at the installation site, in order to ensure the structural safety and the photovoltaic system performance.
