Types of Mounting Structures for Solar Panels: 7 Key Systems

Choosing the right type of mounting structure is crucial for the success of a photovoltaic system. The primary categories include ground-mounted, roof-mounted, and tracking systems. Ground-mounted systems are ideal for large-scale solar farms; they can be fixed-tilt, which offers a cost-effective solution with minimal moving parts, or tracking systems that follow the sun to increase energy yield by up to 25% for single-axis and up to 40% for dual-axis trackers. Roof-mounted systems, on the other hand, maximize space utilization and are commonly used in residential and commercial buildings. They include rail-based systems, which provide flexible positioning of panels, and ballasted systems, which weigh down the panels without penetrating the roof membrane—perfect for flat commercial roofs. Pole-mounted systems elevate panels to follow the sun manually or automatically, suitable for off-grid applications. At STEEL, we engineer each mounting structure to meet specific wind and snow loads based on geographic location. Our products undergo rigorous testing to ensure structural integrity and compliance with international building codes. By offering a variety of types, we empower our clients to optimize energy harvest while ensuring safety and longevity. Whether you need a solution for a small residential project or a multi-megawatt solar farm, our team provides technical guidance and customized solutions to meet your unique requirements.
