Aluminum Extrusions for the Solar Panel Industry

With the increasing awareness of the environment, businesses are looking for sustainable solutions to power their operations. Solar energy is one of the world’s most popular renewable energy sources today.

By utilizing solar panels, homes and businesses can tap into a clean, cost-effective form of energy that reduces environmental footprint while providing reliable electricity output. 

Many homes, businesses, and even factories are beginning to consider solar power as their primary energy source. But not just any type of solar panel will do. For the system to be efficient and effective, it needs reliable components that can withstand the wear and tear associated with different weather conditions. 

The extrusions are a critical component that determines the durability of any solar panel. These parts hold the photovoltaic cells together and allow them to absorb energy from the sun. Aluminum extrusions are widely used in solar panel systems due to their excellent strength, durability, and environmental friendliness.

Different Types of Extrusions Used in Solar Panels

Aluminum extrusions have many different uses when it comes to manufacturing solar panels. Let us look at some of the popular extrusions used in the solar industry.

The U-Channel

The most common type of extrusion used is the U-channel, typically made up of two long strips that run along either side of a photovoltaic cell. These channels provide extra strength and insulation to the cells. They also ensure the cells are securely held in place.

The L-Channel

The L-channel is another type of extrusion used in solar panels. This channel is usually slightly larger than the U-channel and is designed to provide additional support for heavier photovoltaic cells or modules. 

The Curved Extrusion

Many curved extrusions are also available, which can be used to create a more aesthetically pleasing look regarding the overall design of a solar panel array. Not only do they add visual appeal, but they also improve airflow around the cells by deflecting wind away from them. 


Rails are also used in many solar panel arrays, and they come in different shapes and sizes depending on the application. Rails are typically made of aluminum or stainless steel and provide additional stability to the overall structure of the array. 

Benefits of Aluminum Extrusions for Solar Panels

Aluminum extrusions offer several advantages compared to other materials when it comes to solar panels.


Aluminum is an incredibly strong material that can withstand extreme weather conditions such as high winds and hail storms without losing its structural integrity. This ensures that your solar panel system can keep running even in harsh weather conditions. 

Aluminum extrusions are also highly durable and can last for decades with minimal maintenance. This makes them ideal for long-term use in any solar panel setup. 


Not only is aluminum strong, but it’s also very lightweight, making it easier to install and handle. This helps to reduce the overall cost of a solar panel system. 


Finally, aluminum is one of the most eco-friendly materials available today. It’s 100% recyclable and is made from all-natural elements that are not harmful to the environment.

Final Thoughts

Aluminum extrusions are essential to any solar panel system, as they provide additional strength, insulation, and stability to the cells. Not only that, but aluminum is a safe and eco-friendly material that helps to protect the environment in many ways.
