In the dynamic world of renewable energy, the demand for fixed structures that offer reliability, robustness and versatility is ever-increasing. Soletrax has developed the fixed structure for photovoltaic panels, FIXONE™, aiming to position itself as one of the most reliable solutions on the market.
Design Based on Own Wind Tunnel
The interaction with the wind is one of the most critical challenges for any outdoor structure, especially for fixed structures with photovoltaic panels exposed to harsh weather conditions. To ensure maximum reliability, FIXONE™ has undergone rigorous wind tunnel studies. These studies, developed in collaboration with specialized partners, have allowed for the precise determination of pressure coefficients that enable optimized calculation to shape the design. Thanks to these coefficients, it is possible to achieve optimized sizing that ensures the structure will adequately withstand wind forces, minimizing the risk of structural failure.
Finite Element Software Calculation
The detailed simulation of the FIXONE™ structure is carried out using finite element analysis (FEM) software. This method allows for the creation of models of both the overall structure and the joints between different elements. These models are used to verify that the structure complies with current regulations and to analyze the stress state and deformations in the joints, both in the ultimate limit state (ULS) and the serviceability limit state (SLS). Moreover, these models were validated and calibrated with experimental tests, providing an additional layer of security and reliability.
Joint Load Testing
One of the most critical stages in the development of FIXONE™ is the load testing of all joints between structural elements, auxiliary parts, and bolts. These tests ensure that each component and its connection can withstand the intended loads without failing. The joints are subjected to increasing loads until failure or collapse is reached. This determines the ultimate load of the joint compared to the FEM analysis, allowing for model calibration and further simulations in Soletrax’s laboratories and facilities. By verifying each joint, Soletrax ensures that the structure can withstand the most demanding operational conditions, providing a reliable and durable solution for installing photovoltaic panels.
Precise and Validated 3D Design
To ensure that all FIXONE™ components assemble correctly and function as intended, Soletrax uses a precise and reliable 3D design. This design is validated through assembly tests conducted at our facilities, including the development of a real prototype installed at a photovoltaic plant. These tests verify all necessary regulations and ensure that the structure meets quality and safety standards before large-scale production. This validation process in a controlled environment is crucial for identifying and correcting any potential issues before implementation at the photovoltaic plant.
Specialized Software Calculation
The calculation and sizing of the FIXONE™ structure are optimized for each project. Soletrax uses cutting-edge calculation software, incorporating general and local regulations, for profile sizing and global structure optimization. This software not only calculates the appropriate dimensions of components but also performs specific checks for phenomena such as local buckling, which is especially relevant in formed steel structures. Additionally, for proper design, assembly tolerances and eccentricities in the joints are considered, ensuring a robust and reliable structure under various load conditions, as well as facilitating assembly.
The FIXONE™ fixed structure for photovoltaic panels by Soletrax is not just an advanced technical solution but also a product that has been developed and validated using the most rigorous and modern methods available in structural engineering. From wind tunnel studies to detailed calculations using specialized software and finite elements, every step in the development of FIXONE™ has been designed to ensure its reliability and optimal performance.
Soletrax’s dedication to precision in design and exhaustive validation at all development stages ensures that customers receive a product they can trust. The reliability of FIXONE™ lies not only in its ability to withstand the most demanding loads and weather conditions but also in its design, which facilitates assembly and ensures long-term durability. With FIXONE™, Soletrax has set a new standard in the photovoltaic panel structure industry, providing a solid foundation upon which a more sustainable and energy-efficient future can be built.
In summary, the FIXONE™ structure represents the culmination of years of experience and innovation in the solar energy sector, offering a solution that combines safety, efficiency, and reliability. For those seeking a fixed structure for photovoltaic panels that guarantees maximum performance and longevity, FIXONE™ by Soletrax stands as the ideal choice.
