Very Popular Aluminum Solar Panel Frames

Updated: 15 Apr 2023
The solar panel frame, also known as the aluminum solar panel frame, is the most important component in solar panel assembly. An extruded aluminium frame is used to seal and secure the solar module. This aluminum frame protects the solar cells and glass from damage and breakage.
Compared to other materials used to frame solar panels, aluminum framed PV panels are better protected during transportation. As a result, more and more thin-film solar companies are willing to use aluminum frames in their new solar panel designs.

Why Solar Panels Use Aluminum Frames

The aluminum solar panel frame is combined with the aluminum profile mounting bracket to provide sufficient support for the solar panel. In order to fix the solar panel firmly. Due to the aluminium alloy material's strength, durability and resistance, the aluminum solar panel frames provided by Shenghai Aluminum are all anodized. Why do solar panels use aluminum frames instead of stainless steel or composite panels?

Main reason:
1. Lightweight and high strength: Aluminum is a light but strong metal, which allows the aluminum frame to provide enough structural strength for the solar panel without adding too much weight. This is especially important for solar panels because they are usually installed in outdoor environments and face various weather conditions, including wind, rain, snow, etc., so they need to be strong enough to protect them from damage.
2. Corrosion resistance: Aluminum has good corrosion resistance and can resist various chemical and environmental corrosion that may be encountered on the surface of solar panels, such as in humid climates, salt water, etc. This helps extend the life of the solar panel and maintain its appearance and performance.
3. Good thermal conductivity: Aluminum has good thermal conductivity, which can help solar panels dissipate heat. The solar panel will generate a certain amount of heat when it works. If the heat cannot be effectively dissipated, the performance and life of the solar panel may be affected. The aluminum frame helps the solar panel dissipate heat, which keeps it functioning properly. It also has the function of lightning protection in thunderstorm weather.
4. Easy processing and installation: Aluminum material is easy to process and forms various shapes, so the aluminum framing can be custom-made according to the size and shape of the solar panel to meet different installation needs. In addition, aluminium frames usually have a simple design and installation method, which is convenient for construction personnel to install and maintain.

Why Choose Anodized Aluminum Frames For Solar Panels

Many surface treatments can be used on aluminum frames, such as painted solar frames, PVDF solar frames and electrophoretic solar frames. However, most solar panel frames will use anodized surface treatment.

1. Anodized aluminum is a non-conductive material that will not interrupt the normal operation of the solar panel.
2. It has a high tensile strength and can resist wind, snow and other natural elements.
3. Compared with ordinary aluminum, scorching temperatures do not affect anodised aluminium. Therefore, they will not bend when continuously exposed to the hot sun.
4. Anodized aluminium is highly resistant to corrosive environmental factors, so aluminum solar panel frames will not rust even in humid environments.

The choice of aluminum profiles for solar panel frames has proven to be a very good one. Not only does it protect the solar panel assembly, but it also supports the solar photovoltaic (PV) cells and the EVA encapsulation layer.
