Sun Ballast’s efficient solutions: a ton of energy in little space

The productivity of a photovoltaic system depends on numerous factors, including optimising the available surfaces, especially when space is limited. That’s why solar panel racking systems are necessary. Selecting the most suitable ones is essential as it influences the project’s quality and the installation’s yield.

Sun Ballast systems are fast and easy to install and stand out for their efficiency in optimising the available space. This parameter is essential to evaluate the overall quality of a photovoltaic system, which is strictly related to the amount of energy it generates and the end-customer’s satisfaction. Therefore, relying on a simple and versatile modular racking system ensures a significant advantage during the design and installation stages. Being able to bypass obstacles quickly, adapting to any type of roof, and adjusting the length and distance between panel rows are not tiny details.


Let’s start from 0°

The Sun Ballast Standard system is known worldwide for its versatility. It goes with any type of flat roof, from the sheaths of industrial buildings to the flooring of residential terraces and roofs. Moreover, this system can install panels horizontally and vertically, always ensuring maximum solidity. And thanks to a wide range of inclinations available (from 0° to 30°), it can be used under several conditions, handling shading and maximising the PV system’s productivity. When the goal is to use the whole surface, the 0° Standard system shows all its effectiveness: the PV panels are coplanar to the roof, leaving no space between them. The result is a flat surface fully covered with photovoltaic modules adhering to the roof, ensuring low wind exposure and maximum efficiency and stability.

High power in little space: 5° and 11° Sail-shaped systems

While the Standard 0° system ensures a panel surface coplanar to the roof, the Sun Ballast Sail-shaped system increases the photovoltaic module’s inclinations by 5° or 11°. As a result, spaces are further optimised, making this system the perfect choice when space is at a premium, such as in terraces or small residential buildings. Even for the Sail-shaped system, the distance between PV panel rows is eliminated, and the length can be easily adjusted. This way, the system is effective even in the presence of obstacles. Moreover, covering the entire roof provides high energy levels even in compact areas. In the 11° version, this system can fit three ballasts in sequence. Conversely, the 5° inclination requires six ballasts in a row to form the sail-shaped structure. In any case, the Sail-shaped system ensures high efficiency even for small photovoltaic systems, exploiting all the surfaces available.




5° Sail-shaped Connect system: where productivity and resistance meet

Can you have high productivity and maximum wind resistance at the same time? Sun Ballast 5° Sail-shaped Connect system combines the efficiency of the Sail-shaped system with the stability of the Connect system. With the Sail-shaped Connect system, the PV panel rows are made by arranging the modules in pairs and connecting each (double) row with the next one, creating a stable and balanced interconnected network. Like all Sun Ballast systems, even the Sail-shaped Connect system requires no fastening, ensuring perfect surface integrity, even the paved ones particularly common on terraces and condominiums. This solid, efficient, and easy-to-install solution helps increase the PV system’s productivity and resistance. Moreover, having all the ballasts in one network allows for even load distribution, increasing the system’s overall stability and ensuring absolute balance between resistance and productivity, even in compact spaces.


Eliminating Bad Exposure: the advantages of the East-West system

Optimising spaces while ensuring high productivity even when the building is not well exposed is possible. With the Sun Ballast East-West system, rows are made by pairs of panels in opposite directions. Therefore, the system is exposed to solar radiation for longer hours, ensuring continuous electricity distribution throughout the day. The East-West system is available in various versions. Moreover, Sun Ballast structures are highly versatile, as you can adjust the rows’ length and even distance (eliminating it entirely if needed) depending on the roof’s characteristics. The special arrangement of the PV panels (opposite row pairs) leaves no gap between them, effectively optimising the available roof space while ensuring high and consistent productivity on roofs of any size, from those of industrial buildings to the smaller ones of residential buildings.
