Solar roof brackets can be classified into several main types based on different installation methods and materials. Here are several common types of solar roof brackets:

Slope installation bracket: This type of bracket is installed on a sloping roof and can adapt to different roof angles. There are two main types of inclined installation brackets: direct installation on the roof and additional installation on the roof. Direct installation on the roof involves fixing the bracket onto the roof, while additional installation on the roof involves fixing the solar panels onto the bracket after installation on the roof.
  
Flat installation bracket: This type of bracket is installed on flat roofs, such as factory buildings, warehouses, etc. Flat mounting brackets typically have adjustable angles to maximize the capture of solar energy.

Ground mounted brackets: If the house does not have a suitable roof or requires the installation of a larger capacity solar system, ground mounted brackets are an option. This type of bracket typically uses concrete or steel structures to ensure stability and durability.
  
Wall mounted bracket: A wall mounted bracket is used to install solar panels on a wall, typically on a facade or enclosure. This type of installation is suitable for situations where the ground space needs to be preserved or the roof is not suitable for installation.

The selection of these bracket types depends on factors such as roof structure, installation environment, budget, and personal needs. Before installing a solar system, it is recommended to consult a professional for the most suitable bracket type and installation plan.
