The Solar Structure is the structural backbone of any photovoltaic system, serving as the critical framework that secures solar panels to mounting surfaces and bears all environmental and structural loads—its strength, durability and adaptability directly determine the safety, efficiency and lifespan of the entire solar installation. At Sunforson, we have dedicated over 15 years to the research, development and manufacturing of Solar Structure, establishing ourselves as a global leading supplier of this essential PV infrastructure with a presence in more than 80 countries, partnerships with 50+ key industry players and 25+ proprietary patents that drive continuous innovation in Solar Structure technology. Our Solar Structure is engineered to address the diverse challenges of global solar projects, from varying geographic and climate conditions to different installation scenarios and project scales, and our unwavering commitment to quality, customization and customer service has made our Solar Structure the preferred choice for installers, distributors, project developers and utilities across Europe, Asia, Africa and the Americas.
Every aspect of our Solar Structure is designed with structural integrity and practical performance at its core, crafted from high-grade 6000-series aluminum and high-strength steel selected for their exceptional corrosion resistance, high tensile strength and lightweight properties—critical for reducing installation labor and minimizing structural load on mounting surfaces such as roofs and building walls. The anodized finish of our aluminum Solar Structure components is backed by a 5-year warranty, while the material and workmanship of the entire Solar Structure are guaranteed for 10 years, a testament to our confidence in the long-term durability of our products. Our Solar Structure is manufactured in strict compliance with international PV and building standards including EN 1090, and all variants hold authoritative global certifications such as CE, CSM, Anbotek and GRG. These certifications ensure that our Solar Structure meets the strict safety and technical requirements of every country and region we serve, streamlining project approval processes and eliminating technical barriers for our global customers, who can integrate our Solar Structure into their projects with minimal administrative effort and maximum peace of mind.
The Solar Structure product line at Sunforson is fully integrated, covering every major PV mounting scenario with specialized designs optimized for each application, ensuring that customers have a tailored framework solution for their specific project needs without the need to source components from multiple suppliers. For roof-mounted solar projects, our roof Solar Structure is divided into pitched and flat roof variants, each engineered to match the unique characteristics of the mounting surface while preserving the structural integrity of the host building. The pitched roof Solar Structure features non-penetrating roof attachment systems that secure to tile, metal, asphalt and asbestos roofs without drilling holes, eliminating the risk of water leakage and structural damage, and its pre-assembled clamps and rails allow for fast on-site assembly, reducing labor costs and project timelines. The flat roof Solar Structure is designed with a modular ballasted base that uses concrete weights for stability, requiring no roof penetration and making it ideal for commercial and industrial flat roof installations with strict structural requirements. What sets our roof Solar Structure apart is its universal compatibility with all framed and thin film solar panels of any size, ensuring that customers can use the same Solar Structure for different panel types across multiple projects, reducing inventory costs and supply chain complexity.
For ground-mounted solar installations, our ground Solar Structure is available in four specialized variants—concrete based, ground screw, pile and single pole—each designed to adapt to different soil types, from soft clay and sand to hard rock and concrete. This Solar Structure features a large-span design between leg groups, which maximizes land utilization by reducing the number of support structures required, and also optimizes the use of aluminum material, making it the most cost-effective solution for commercial and utility-scale ground PV projects that require large land coverage. The ground Solar Structure is engineered for quick on-site assembly with minimal site preparation, and its robust construction is tested to withstand extreme weather conditions including high winds of up to 120km/h, heavy snow loads and extreme temperature fluctuations from -40°C to 85°C, ensuring stable performance for decades with minimal maintenance. Our technical team provides professional guidance on selecting the right variant of the ground Solar Structure based on the customer’s soil testing data, wind load calculations and project scale, ensuring that the Solar Structure is perfectly matched to the project’s specific conditions and delivers maximum structural performance and value.
For integrated solar solutions that combine energy production with functional design, our carport and wall Solar Structure deliver unrivaled versatility, structural strength and aesthetic appeal. Our carport Solar Structure is designed for both single and double row parking setups, compatible with all solar panel types and sizes, and it not only provides a high-strength framework for solar panels but also offers durable shade for parked vehicles, making it an ideal solution for residential communities, commercial parking lots, shopping malls and industrial facilities. The carport Solar Structure is customizable to match the architectural style of the surrounding area, with a modular design that allows for easy expansion and a durable construction that withstands heavy use and extreme weather. Our wall Solar Structure is a rail-free, economical design for building facade PV installations, engineered with customizable mounting angles to optimize solar energy absorption for any wall surface—vertical, horizontal or sloped. This Solar Structure features a hidden mounting design that keeps the framework out of sight, ensuring a sleek and aesthetically pleasing appearance for urban residential and commercial buildings where architectural design is a key consideration, while its robust construction ensures that solar panels are tightly fixed to the wall and can withstand high wind speeds without compromising structural stability.
We understand that every solar project has unique structural requirements, which is why we offer comprehensive OEM&ODM customization for our entire Solar Structure product line. Our team of technical experts and structural engineers, with rich experience in engineering, manufacturing and international building standards, works closely with customers to understand their project’s specific needs—including solar panel type, mounting surface, regional climate, wind/snow load requirements and project scale—and design a tailor-made Solar Structure that meets these exact specifications.
