Highly reflective bright aluminium for solar energy systems by Aludium.

Aluminium is a vital material in the production of solar energy from both thermal and photovoltaic (PV) concentrating installations. Lightweight, easy to form, and highly reflective, aluminium is the perfect material to enhance solar applications.

Aludium produces alloys which are suitable for both the structural and reflective elements of solar installations. Our bright sheets and coils have been developed to withstand tough outdoor conditions, ensuring they can be used wherever the sun shines.

As well as bright finishes suitable for mirrors, Aludium’s portfolio includes alloys and substrates for absorber applications. Our products are used in applications including:

  • Solar collectors for domestic water and space heating
  • Concentrating solar power (CSP) troughs
  • Concentrating PV applications
  • PV and thermal panels for buildings.

See the table below for more information about Aludium’s solar energy portfolio.

Aluminium with high surface quality for solar collectors and degreased for direct PVD coating and application of selective surfaces (SolGel). This is the most common alloy for solar applications. Depending on customer requirements, Aludium can supply other suitable alloys.
