GENERAL FEATURES OF THE INSTALLATION

The photovoltaic installations are connected to Enel’s public distribution network at low voltage (LV) or medium voltage (MV) and consist of the following elements:

​

  • Photovoltaic field

  • Parallel combiner boxes for the strings

  • Power conversion and control systems (inverters)

  • Step-up transformer from low to medium voltage (LV/MV)

  • Protection, switching, and interface devices for LV/MV

  • Power supply for auxiliary systems

  • Uninterruptible power supply systems (UPS) for auxiliary services and protections of the electrical substation

  • Conductors for connection between components, grounding, and linking to Enel’s public LV/MV network

PANEL SPECIFICATIONS

The photovoltaic modules are composed of:

​

  • A backsheet made of insulating material to protect the module

  • 60-72 polycrystalline cells connected in series

  • Two sheets of encapsulating material

  • A tempered glass with high transmissivity

  • An anodized aluminum frame

​

Each module includes:

  • A junction box with IP65 protection rating

  • Pre-wiring with 4 mm² solar cable and Multi-Contact type connectors

  • An identification label containing:

    • Manufacturer’s name

    • Model with electrical and mechanical specifications

    • Barcode and serial number visible under the glass (to prevent reuse in case of theft)

CARACTERÍSTICAS DE ANCLAJE

Las instalaciones fotovoltaicas están distribuidas en varias azoteas diferenciadas. Todas las estructuras montadas sobre las cubiertas están interconectadas mediante accesorios especiales para formar una estructura de red única (tipo balsa), lo cual permite reducir el número de contrapesos necesarios.

​

The structure consists of:

  • Base rails fixed directly onto the roof

  • On these, triangles (tilted supports) are mounted at specific intervals

  • On top of the triangles, the beams are placed where the modules are fixed

  • The inclination of the triangles is determined by the height of the parapets on each section of the roof

  • Crossbeams are also installed to complete the structural grid and allow the entire system to be anchored to the perimeter walls

​

All the described elements are made from X-type profiles in aluminum EN AW-6060, ensuring lightness, corrosion resistance, and structural durability.
