Aluminium Brackets vs. Steel Brackets for Solar Panels Mounting: Why Quality Matters

Choosing the suitable bracket material for mounting solar panels affects efficiency and longevity. Aluminium and steel are popular options, each with benefits and drawbacks. Understanding these differences helps you decide better. Here’s why bracket quality matters.

What are Aluminium Mounting Brackets?

Aluminium mounting brackets are lightweight and resist corrosion, making them ideal for outdoor use. They are also easier to install than steel brackets and require less structural support. Plus, their rust resistance means long-term durability, reducing maintenance and extending the life of your solar panel system.

What are Steel Mounting Brackets for Solar Panels?

Made from various types of steel, these mounting brackets can handle heavy loads and harsh weather, giving you peace of mind for your solar setup. Their high tensile strength offers solid support, even in high winds or heavy snow. Often coated to resist rust and corrosion, these brackets last longer.

Differences Between Aluminum and Steel Solar Panel Brackets

Material

Aluminium brackets are lightweight and rust-free, ideal for damp areas. While incredibly strong and durable, steel brackets need proper treatment or coating to avoid rust.

Production Method

Aluminium brackets are made by extrusion, allowing for precise and complex shapes. Steel brackets are created through stamping or forging, providing strong structure and efficient mass production.

Bracket Shape

Aluminium brackets can be shaped into detailed and custom designs using extrusion. Steel brackets are usually simple and robust, focusing on support rather than looks.

Bracket Combining Method

Welding or riveting joins aluminium brackets for a robust and lightweight connection. Welding, bolting, or heavy-duty fasteners join steel brackets for secure, stable assemblies that handle heavy loads.

Size

Aluminum brackets are lightweight and come in various sizes, making them really easy to handle. On the other hand, steel brackets also come in different sizes but are much heavier, so they’re not ideal if you’re worried about weight.

Weight of the Bracket

Aluminium brackets are lighter than steel ones. They’re easier to install and handle, especially overhead. Steel brackets are heavier but much more robust and more stable. They’re best for heavy-duty use.

Alternate Installation Options

Aluminium brackets are easy to install with standard tools. Steel brackets, being heavy and strong, need specialised tools and extra support for installation.

Weight Capacity

Steel brackets can handle heavier loads than aluminium ones, making them perfect for structural uses. On the other hand, aluminium brackets aren’t as strong but are great for lighter to moderate loads and are loved for their light weight.

Cost

Because of raw materials and manufacturing costs, aluminium brackets are more expensive than steel ones. They resist corrosion and are lighter, which can justify the higher price. Steel brackets are cheaper and suitable for high-strength needs but may require rust prevention.

Benefits of Using Aluminium Brackets for Solar Panel Mounting

Low Weight

Aluminium brackets are much lighter than traditional materials. Installation is more accessible and less labour-intensive. The reduced weight decreases the load on the roof, enhancing safety and longevity.

Corrosion-Resistive

Aluminium forms a protective oxide layer, making it resistant to corrosion. It can handle harsh environments, ensuring long-lasting durability. Less maintenance is needed, and it has an extended lifespan. Your solar panel mounting system will stay strong and reliable for years.

Strong

Aluminium is lightweight yet incredibly strong. It can withstand heavy loads and extreme weather. This ensures the mounting system is secure and reliable, protecting your solar investment.

Compatible

Aluminium brackets are versatile and work with many solar panels and roof structures. They allow for easy customisation and integration into different solar systems, ensuring efficient installations.

Choosing Aluminium Brackets for Solar Panel Mounting

Factors to Consider When Choosing Aluminium Brackets for Solar Panel Mounting

  • Material quality and composition
  • Load-bearing capacity
  • Corrosion resistance
  • Compatibility with different roof types
  • Ease of installation

Safety Tips for Mounting Brackets in Solar Panel Systems

  • Follow Manufacturer Instructions: Adhere to installation guidelines for proper mounting and safety.
  • Use the Right Tools: Always use the correct tools to avoid accidents and damage.
  • Ensure Proper Grounding: Ensure all components are grounded to prevent electrical hazards.
  • Check Structural Integrity: Inspect the roof for any weaknesses before installing.
  • Wear Protective Gear: Protect yourself with gloves, safety glasses, and helmets.
  • Work with a Partner: Have someone help with lifting and securing brackets.
  • Secure Ladders and Scaffolding: Make sure ladders and scaffolding are positioned securely to avoid falls.
  • Think About the Weather: Avoid working in bad weather.
  • Do Regular Maintenance Checks: Inspect the mounting system for any issues.
  • Get Proper Training and Certification: Ensure all installers are trained and certified.

Choosing the Right Material: Aluminium Solar Panel Brackets vs. Steel Solar Panel Brackets

Both aluminium and steel have their benefits. The best choice depends on your project’s needs.

Aluminium brackets are lightweight, resist corrosion, and are easy to install. They are great for homes and small businesses.

Steel brackets are stronger and can hold more weight, making them ideal for heavy-duty and industrial use.

Think about load capacity, environmental conditions, and how you will install them.

FAQs

How much do Aluminium Brackets cost in South Africa?

The cost of alum brackets in South Africa varies. Size, design, and manufacturer influence the price of the product. On average, expect to pay between ZAR 100 and ZAR 300 per bracket. Buying in bulk, customisations, or added features can raise the cost. Get quotes from several suppliers to find the best deal. Make sure the brackets meet your quality and performance needs.

What’s the Difference Between Stainless Steel and Aluminium Brackets?

Stainless steel brackets are solid and durable, perfect for heavy-duty tasks. They resist mechanical stress and support heavy loads without bending. They also resist corrosion well, even in harsh conditions, which increases their lifespan.

Aluminium brackets are lighter and easier to handle and install. They resist corrosion due to a natural oxide layer on their surface.

Choose between stainless steel and aluminium based on your project’s needs, such as load capacity, environmental conditions, and ease of installation.

Why is Aluminium Better for Solar Mounting Brackets?

Aluminium is excellent for solar mounting brackets because it is lightweight and corrosion-resistant. It is easy to handle and install. Despite being light, it remains durable, ensuring long-term performance.
