The Zambelli HSF Ballast Tank

The Zambelli HSF Ballast Tank is a substructure designed for the proper and secure installation of photovoltaic systems on flat roofs. Made from UV-resistant high-performance plastic (HDPE), this mounting system combines east-west elevation and ballasting in one.

The pressure-free, open tank system is suitable for year-round use – even in icy conditions during winter! Ballasting is achieved by filling the tank with water. This allows the mounting system to function without penetrating the roof membrane or requiring additional weighting with ballast stones. An automatic precipitation return system ensures that evaporated ballast water is redirected into the ballast tank via the funnel cap during rain, keeping the water level constant.
