On-roof PV mounting system SunNet Roof

SunNet Roof is a steel cable-made mounting system for rooftop photovoltaic plants. SunNet Roof is anchored on the roof perimeter by anchorages, which offer an easy way to tension steel wire ropes. Easels simply lay (no anchored) at the center of the roof keeping steel cables lifted at the desired height. Easels of adjacent arrays are rigidly connected. Photovoltaic panels are hooked on the steel wire ropes by special hooks that speed up the installation. To facilitate the installation process, SunNet Roof is delivered preassembled with cables at the right length. Installer only unfolds SunNet Roof and anchors it at the roof. Both structures and wire ropes are made with hot dip galvanized steel. Screws in stainless steel. SunNet Roof complies with Italian law 14/01/2008 which recommends, for safety, that photovoltaic plants stability do not merely rely on friction effect (ballast usage), but they have to be linked to the roof by stiff or flexible means. Traditional solutions with ballast do not comply with this law. The fastest to install. A structure for 1kw panels, including panels, is installed in 50 minutes by one operator. Preassembled system with wire ropes cut at size is only made by 3 components: anchorages, preassembled structure, hooks for panels. SunNet Roof is installed with simple tools in only 3 steps: 1) place anchorages 2) unfold and anchor structure 3) hook panels to wire ropes. - NO Ballast. Adjacent arrays are connected rigidly with each other becoming a single stable structure. Steel wire ropes are firmly anchored and assure SunNet Roof against wind forces up to 130 km/h (80 miles/hour) without any ballast.
