Photovoltaic frames, commonly referred to as the fixed structures installed around the edges of photovoltaic modules, primarily serve to protect the solar panels from mechanical damage while ensuring the stability and safety of the modules during installation and transportation. Below is a detailed description of photovoltaic frames:

1. Material: Photovoltaic frames are commonly made of aluminum alloy, stainless steel, or plastic, with aluminum alloy frames being widely used.

2. Structure: The photovoltaic frame is divided into the upper and lower frames. The upper frame primarily serves to secure and support the photovoltaic panels, while the lower frame is responsible for sealing and securing the panels.

3. Dimensions: The size of the photovoltaic frame typically matches the size of the photovoltaic panel to ensure a tight fit between the frame and the panel.

4. Color: The color of photovoltaic frames is usually black, gray, or white, coordinating with the color of the photovoltaic panels.

5. Weather Resistance: Photovoltaic frames should possess excellent weather resistance, maintaining stability and reliability under various harsh environments.

6. Installation Methods: There are mainly two ways to install photovoltaic frames – one is to directly install them at the bottom of the photovoltaic modules, and the other is to use brackets for installation.

7. Advantages: Photovoltaic frames possess the following advantages:

o Protect photovoltaic panels: Prevent mechanical damage to the panels during installation, transportation, and operation.

o Enhance the stability of photovoltaic modules: Ensure the panels remain stable under harsh conditions such as wind and rain.

o Aesthetics: The frame color coordinates with the battery panel color, enhancing the photovoltaic power system's visual appeal.
