Aluminum frames provide multiple critical protections and support for photovoltaic panels through their unique material properties and structural design

Structural support and strength protection

Enhanced mechanical strength: The photovoltaic panel itself is composed of brittle glass and silicon wafers. The aluminum frame acts as a sturdy skeleton, greatly enhancing the overall mechanical strength of the components, enabling them to withstand the static and dynamic loads caused by harsh weather conditions such as strong winds, heavy snow (especially the snow pressure of distributed photovoltaics).

Preventing deformation and cracking: During transportation, installation, and long-term use, the frame can effectively prevent the misalignment and bending of the board layers, thereby protecting the internal battery cells and wires from stress damage and hidden cracking or breakage.

Sealing protection and weather resistance

Moisture and corrosion prevention: The aluminum frame is sealed with laminated glass and backplate using silicone, creating a sealed environment that effectively blocks the intrusion of water vapor, dust, and corrosive gases. This is crucial for protecting EVA film and battery circuits that are prone to moisture aging, and is the key to ensuring a lifespan of over 25 years for the components.

Coping with extreme temperatures: Aluminum has good thermal stability and can adapt to drastic temperature changes from extreme cold to scorching heat without failure.

Convenient installation and grounding

Standardized installation interface: The installation holes and slots designed on the frame enable it to be quickly and securely fixed to various bracket systems, greatly improving installation efficiency and reducing labor costs. This is the foundation for achieving large-scale and rapid deployment of photovoltaic power plants.

Natural grounding path: Aluminum is an excellent conductor. Through dedicated grounding holes and clamps, all photovoltaic panels can be easily connected into an equipotential body through the frame, achieving safe and reliable system grounding and preventing the dangers caused by lightning strikes and static electricity accumulation.

Lightweight and durability

High strength to weight ratio: While providing sufficient support, the aluminum frame maintains a relatively light weight, reducing the load on the roof and brackets, and facilitating handling and installation.

Corrosion resistance: Aluminum frames for photovoltaics are usually treated with anodizing, forming a hard and corrosion-resistant oxide film on the surface, which can resist the erosion of ultraviolet rays, rainwater, and salt spray for a long time, ensuring that they will not rust for decades in outdoor environments.
