Photovoltaic new energy support purlin

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.

How are photovoltaic supports modeled?

All components of the photovoltaic supports were modeled using eight-node linear hexahedral solid elements (C3D8R). The simulation included parameters where two or three bolts were installed at the purlin hangers to investigate the effects of different connection methods on joint deformation; a schematic diagram is shown in Figure 7.
