Frequent questions

Omniablok is a structural support system for the photovoltaic panels, developed and introduced to the market by Omnia Spatial Structures SRL since 2010. It derives its name from the Omniablok aluminium casting, crafted from EN AB 46100 alloy, enabling the connection of grid elements forming the photovoltaic frame.

The Omniablok structure comprises hot-dip galvanized s235 steel tubes, lightweight aluminium alloy castings, and the bolts are fabricated from A2 stainless steel, all branded “OMNIA”.

The number of fasteners depends on the layout, the type of the roof, and the installation area;
each structure is customized based on its specific characteristics, and the fastening points vary accordingly. Our technicians create a design indicating the fastening points, typically positions along the perimeter of the roof, aiming to avoid fixings inside the roof slope.
One of the advantages of the Omniablok system is the ability to install with minimal drilling compared to the traditional standard structures.

No, each Omniablok structure is tailor-made according to the dimensions of the photovoltaic panel to be installed.

No, Omniablok structures are straightforward and fast to assemble.
Installers can assemble Omniablok instead of standard systems without needing to attend training courses.

The Omniablok structure weighs around 9.8 kg/m2 for a flat roof and approximately 6.5 kg/m2 for a sloped roof. The weigh can vary depending on the size of the photovoltaic panel.

No, our systems are tailored for roofs and are developed from our extensive expertise in roofing solutions

Are additonal clamps required for installation? No, the Omniablok structure comes complete with bolts and all necessary components for panel attachment

Certainly upon request, we can supply a snow guard for the end section of the structure, or a snow guard to be installed among the photovoltaic panels

You can request a quote by emailing
and attaching a layout showing module arrangement, technical data sheet of photovoltaic panels, shipping address, and any available photos of the roof
