Photovoltaic Purlins Profile Steel
A purlin in photovoltaic mounting systems is a horizontal beam or bar that serves as the primary support structure for the solar panels. It is mounted perpendicular to the main rafters or trusses of a structure
4 FAQs about Photovoltaic solar panel purlin installation
Why do solar panels need a purlin?
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.
Why do solar purlins need galvanized steel?
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.
What are purlins used for?
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. In solar mounting systems, the most common types are C Purlins and Z Purlins.
What is a Z purlin?
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. Purlins play a direct role in holding solar panels securely in place.
