Enerix Weimar, the most important German distributor, chooses Sun Ballast for the construction of photovoltaic systems on flat roofs. As in this system built on a portion of the roof inside an apartment building, bordered on both sides by the presence of obstacles. But despite the obstacles present on the roof, an installation was made with brushes in horizontal laying on the concrete structures of Connect System with an inclination of 10 °. Sun Ballast structures do not require holes on the roof to be installed, which is why installation is quick and easy, while still guaranteeing strong wind resistance despite the low load on the roof. The result is a tidy, clean plant capable of producing 19.8 kWp of clean energy.
