The spacing between the hooks of the solar tile roof depends on multiple factors, including but not limited to the following:

1. Tile type and size: Different types and sizes of tiles may require different hook spacing. Generally speaking, the spacing between hooks should be sufficient to support the weight of the solar panel and ensure safe and stable installation.

2. Roof structure and materials: The structure and materials of tile roofs can also affect the spacing of hooks. If the roof structure is relatively sturdy, the spacing between the hooks can be appropriately increased; If the roof structure is weak or has limitations, the spacing may need to be reduced to increase support.

3. Local climate and wind load requirements: For areas with harsh climate conditions and high wind load requirements, tighter hook spacing is usually used to increase system stability and wind resistance.
