Solar Mounting Structures
Solar mounting structures are the backbone of photovoltaic (PV) systems, providing stability, durability, and the correct orientation of solar panels. These structures are typically made of steel or aluminum and must withstand wind, snow, and other environmental stresses. Among the critical components of these structures are purlins, which play a vital role in ensuring strength and efficiency.
What Are Purlins?
Purlins are horizontal structural members that provide support to solar panels within a mounting system. Traditionally used in roofing and steel construction, purlins are now widely adapted for solar energy applications. They serve as intermediate supports between the main beams and the panels, distributing loads evenly and preventing structural deformation.
Types of Purlins Used in Solar Structures
In solar mounting systems, the most common types are C Purlins and Z Purlins.
- C Purlins offer high strength and are often used for medium spans.
- Z Purlins provide better overlapping and load distribution, making them suitable for larger installations.
Both types are manufactured using advanced roll forming machines, ensuring precision, consistency, and long-term durability.
Steel Purlin Making Machine
Purlins play a direct role in holding solar panels securely in place. By creating a reliable framework, they prevent bending, sagging, or shifting of panels over time. This ensures that the panels maintain their correct angle and orientation, which is essential for maximum sunlight absorption and energy generation.
Material Selection and Corrosion Resistance
Since solar structures are exposed to outdoor conditions for decades, purlins must be manufactured from high quality galvanized steel or aluminum. Galvanized coatings provide excellent corrosion resistance, protecting the structure from rust and extending its lifespan. At LOTOSFORMING, purlins are designed to meet international quality standards, ensuring both strength and durability in demanding environments.
Benefits of Using Roll Formed Purlins in Solar Projects
Roll formed purlins offer several advantages for solar mounting applications:
- Precision in dimensions for accurate installation.
- Lightweight yet strong profiles for easier handling.
- Cost effectiveness due to efficient coil processing.
- Flexibility in design, allowing customization according to project requirements.
These benefits make roll-formed purlins the preferred choice for large-scale solar power plants and rooftop installations.
