Fixed bracket: Fixed bracket is the simplest and most common type. They are composed of stable metal structures used for installing solar panels and maintaining them in a fixed position and angle. This type of bracket is typically installed on the roof or floor of a building and does not automatically adjust with the position of the sun.

Horn mouth bracket: Horn mouth bracket is also known as concentrated solar energy system. They improve energy harvesting efficiency by using convex lenses or mirrors to concentrate the sun's rays onto solar panels. This type of bracket is typically used for applications that require high energy density and smaller solar panels, such as solar thermal power plants or solar laboratories. The horn mouth bracket usually requires a precise tracking system to ensure that the sunlight is accurately focused on the solar panel.
