Aluminum Extrusions in Energy

Aluminum extrusions play a key role in both alternative and conventional energy generation and distribution systems. Traditionally, aluminum's high electrical conductivity (about 62% of that of copper on an equal volume comparison and two times that of copper on an equal weight basis) has made extrusion a frequent choice for electrical connectors and for bus bar systems used to distribute power in industrial facilities.

Solar Power

Today, extrusion is earning its place as a key component in solar power - providing cost-effective mounting and racking solutions for concentrated (CSP), photovoltaic (PV), concentrated photovoltaic (CPV), and building iintegrated photovoltaic (BIPV) solar power systems.

Aluminum Extrusion in PV

Extrusion's light weight and low maintenance make it an excellent choice for PV mounting systems—whether for industrial roofs, residential roofs, or large/utility scale ground-mount systems. In addition, the ability to design in multiple functions—like wiring raceways and connectors—can significantly reduce parts and speed installation, leading to reduced system costs. 

PV Studies

A recent study commissioned by the AEC and conducted by IBIS Associates concluded that aluminum extrusion mounting systems were an economical alternative to steel in all PV market segments when the total costs of materials, other components, shipping, and installation were considered. And that was before the reduced maintenance costs and residual recycling value of aluminum extrusions was factored in!

Aluminum Extrusion in Wind Power

Extrusion is increasingly found in wind power. From bus bar to carry the electricity generated by the turbine to inner-tower structural elements, platforms, and ladders, extrusions and extrusion-based assemblies play a prominent role.
