Modules with high mechanical strength, high electrical insulation performance and excellent anti-PID performance: DAH Solar has also been offering its customers in Latin America the option of modules with a composite frame.
Today, the current situation regarding aluminum frames for photovoltaic modules is influenced by rising aluminum prices, which can have significant variations in price per ton, leading to increased costs for the final product. Reducing the weight of the aluminum frame can directly decrease material costs, thus reducing the total cost of the module.
However, offering this type of product to the market can be dangerous. After reducing the weight of the aluminum frame, the structure will not be able to effectively withstand strong winds and snow, as well as the mechanical stresses that may occur during installation and maintenance.
In this sense, the idea is not to stop working with aluminum frame modules, but rather to offer a more competitive alternative with excellent mechanical and electrical characteristics, namely composite frame modules.
Composite materials are modern products obtained through the controlled combination of two or more materials with distinct properties, resulting in a final material with superior characteristics. These composites are generally formed by three main components: matrix, reinforcement, and adhesive.
Therefore, composites are materials formed by combining a matrix (continuous phase) with a reinforcement (fibers, particles) to create improved properties, and the application of these materials is widespread in other sectors, such as aerospace and automotive, brake and engine parts, and products that are often subjected to high temperatures.
Composite materials offer advantages such as cost savings, lightweight yet high-strength products, flexible design, high-grade electrical insulation, excellent corrosion resistance, and low carbon emissions during production, making the supply chain even more sustainable.

Composite frames can be made of high-strength fiberglass, modified acrylic resin, modified polyamide (coating), and high-strength polyphenylene oxide (frame corners).
These combined elements provide high strength and corrosion resistance, high tensile strength and high thermal distortion temperature, improved performance by reducing water absorption, and high weather resistance.
Furthermore, the performance advantages of composite frames for photovoltaic modules include:


The composite frame offers significantly greater resistance to static and dynamic loads compared to the IEC standard, with 100% resilience and no irreversible deformation. Its safety factor against salt spray corrosion is superior to that of metallic structures.
Furthermore, both the materials and the photovoltaic modules with composite frames comply with the relevant regulations.

Here are some tests conducted for certification that can be highlighted in this article:
In summary, the performance advantages of composite frames for photovoltaic modules are:
