Ballast system for flat roofs: Sthenos GB Solar

Sthenos it is the system patented by GB Solar Designed to optimize the installation of photovoltaic systems on flat roofs. This structure modular and scalable , composed of universal concrete ballasts , which eliminates the need for mechanical fixings to the roofing, significantly simplifying assembly and reducing installation times up to 70% . Structure and Components The system consists of three pre-assembled blocks : Front Block (GBAxx) Rear block (GBZxx) Adjustable intermediate block (GBTxx) , which allows for quick configuration of the pitch between panels These elements, once connected, form files in solidarity with each other , ensuring structural stability and a homogeneous distribution of loads. The adjustable central ballast – heart of the system – allows the adaptation of the spacing between the rows based on the latitude and geographical position , thus optimizing shading. Sthenos is available in different inclinations : 5th, 10th and 15th , adaptable to any type of project. To ensure maximum precision during installation, the system can be equipped with a coplanarity adapter : a technical accessory designed for compensate for unevenness or irregularities in the support surface , such as those found on concrete or bituminous sheath surfaces. This component allows you to keep the modules perfectly aligned and coplanar , improving both the aesthetics of the system and the stability of the structure, while ensuring compliance with the tolerances required by the main photovoltaic module manufacturers. Flexibility and Installation Types The system is designed to offer maximum compatibility with the main photovoltaic modules on the market, respecting the fastening specifications recommended by the manufacturers. You can install the panels: With locking on the long or short side In East-West or South configurations With the possibility of increasing the anchor points from 4 to 6 (or more) , without the need for additional brackets The different configurations (1–6) allow the designer to maximum compositional freedom , depending on the technical and dimensional needs of the site. Configuration 1 and 2: possibility of fixing the module to the ballasts either on the long side or on the short side Configuration 3 and 4: possibility of fixing the module to the ballasts either on the long side or on the short side with a coplanarity adapter for non-standard modules Configuration 5: mixed system with standard ballast and central reinforcement characterised by the sthenos system Configuration 6: 6-point module locking system Main Benefits Very quick installation : up to 70% faster thanks to snap-fit ​​assembly High wind resistance , tested in the wind tunnel Modularity and customization : adaptable to any project, even on a large scale Lower overall weight on the roof and better resistance to wind load Reduction of logistics and transport costs Less manpower required in the process of being assembled Total absence of mechanical components to assemble Why consider Sthenos in your photovoltaic projects Many flat roof projects, especially in commercial and industrial settings, require a structure that simplifies installation without compromising stability and durability. A modular system like this can be useful when time on site is limited, the roof conditions don't allow for mechanical fastenings, or logistical complexity needs to be reduced. The ability to work with pre-assembled elements, combined with good design flexibility, make it a strategic choice for those seeking reliability, efficiency and flexibility under construction.
