Alloys for Solar Power
At City Special Metals, we supply high-performance alloys used across the solar industry, supporting manufacturers of aluminium solar panels, mounting systems, and structural components. Our materials are selected for their strength, corrosion resistance, and long-term stability in outdoor environments.
We work closely with solar panel manufacturers, fabricators, and procurement teams to provide a reliable stock of specialist metals for demanding applications. Whether you’re producing aluminium solar panel frames or solar panel brackets, or working on large-scale renewable energy projects, we ensure consistent supply and quality.
Alloy Properties for Solar Applications
Solar energy systems operate in exposed environments, often for 20+ years. Materials must perform reliably under constant UV exposure, temperature changes, and weather conditions without degradation.
Key properties required for solar applications include:
- High corrosion resistance for long-term outdoor use
- Strong strength-to-weight ratio for structural efficiency
- Excellent thermal stability across varying climates
- Good for fabrication and assembly
- Resistance to oxidation and environmental wear
Our alloys are selected to meet these requirements and can be supplied in multiple forms depending on your manufacturing needs.
Materials Used in Solar Panel Manufacturing
Aluminium
Aluminium is widely used across the solar industry due to its lightweight nature, corrosion resistance, and ease of fabrication. It is the primary material used in aluminium solar panel frames, offering durability without adding unnecessary weight.
We supply aluminium for:
- Aluminium solar panel frames
- Aluminium solar panel brackets
- Mounting systems and structural supports
Stainless Steel
Stainless steel is commonly used in solar panel brackets and fixings where additional strength and corrosion resistance are required. It performs well in harsh environments, including coastal and industrial locations.
Nickel Alloys
Nickel alloys are used in more specialised solar applications where high temperatures or aggressive environments are present. These materials provide excellent durability and resistance to oxidation.
Copper
Copper offers high electrical conductivity and is used in solar systems for wiring, connectors, and energy transfer components. High-purity copper ensures efficient performance and reduced energy loss.

FAQs
What materials are used in aluminium solar panels?
Aluminium is the primary material used in aluminium solar panels, particularly for frames and structural components. It provides a balance of strength, durability, and corrosion resistance, making it ideal for long-term outdoor use.
Why is aluminium used for solar panel frames?
Aluminium is lightweight, corrosion-resistant, and easy to manufacture, which makes it the preferred choice for aluminium solar panel frames. It helps reduce overall system weight while maintaining structural integrity.
What are solar panel brackets made from?
Solar panel brackets are typically made from aluminium or stainless steel. Aluminium solar panel brackets are lightweight and corrosion-resistant, while stainless steel is used where additional strength is required.
