19 Aug Metal structures: the basis of an efficient solar installation

In the world of solar energy, not only photovoltaic panels play a crucial role; the metal structures that support them are just as important to ensure a safe, efficient and durable installation. In this article we will look at why they are so important and the regulations that govern them.

What are metal structures for solar panels?

Metal structures are components designed to support solar panels, whether on roofs, floors or specific installations such as solar pergolas. Their main function is to provide stability, proper orientation and resistance to factors such as wind and snow loads.

There are different types of structures depending on the use:

• Fixed, ideal for flat roofs and terrains.
  
• Orientable, allowing the angle of inclination to be adjusted according to the season of the year.
  
• Solar trackers, which maximize radiation capture by moving close to the sun.
  

Most of these materials are recoverable, allowing for efficient and cost-effective recycling.

Importance of regulatory compliance

In Europe, metal structures for solar panels must comply with the UNE-EN 1090-1 standard, which regulates aspects such as mechanical strength, load-bearing capacity and durability. In addition, CE marking is mandatory, certifying that the product meets the required quality and safety standards. This process includes factory production evaluations and technical documentation, such as the Declaration of Performance (DoP).

Benefits of quality structures

• Safety: Prevent accidents and long-term damage.
• Energy efficiency: Its design allows optimal positioning of the panels to maximize solar gain.
• Durability: Resistant to corrosion and wear, prolonging the service life of the installation.

Alusín Solar’s commitment

At Alusín Solar we understand that each project has specific needs. In Alusín Solar we have specialized in the manufacture of aluminum and galvanized steel structures for photovoltaic panels for all types of applications: from solar pumping systems for large areas to the installation of solar panels on factory roofs.

All our roofing systems are manufactured with extruded aluminum profiles in various alloys and all hardware is supplied in A2 quality stainless steel. For extreme climates there is also the possibility of manufacturing all profiles anodized with A4 quality hardware. Our floor systems also incorporate galvanized steel as a material, thus reinforcing their resistance and stability.
