The invention belongs to the technology field of adopting the new material and structure of a ceramic, etc. The former solar energy collector mainly comprises a low temperature type sunlight absorption coating, a structure layer and a heat insulating layer, which are coated on a copper aluminum compound tube plate type solar energy collector, and a transparent cover plate, or consists of vacuum glass tubes. The cost is high, the service life is short, and because the coating gets older, the average efficiency is not high. The ceramic solar energy collector consists of a ceramic sun board, a heat insulating layer and a transparent cover plate, the structure is simple, the installation is convenient, the production cost of the ceramic sun board is low, the ceramic solar energy collector does not age and can be collided, a black porcelain sunlight absorption layer is formed by burning above 1000 DEG C, the sunlight absorption rate does not attenuate nearly, a sun board heat collecting box which is manufactured according to the manufacture and the installation method of the ceramic sun board collector is securer and more reliable to the assembly and disassembly and the transportation of the ceramic sun board, the modularized and rapid installation can be realized, when being assembled, a solar energy roof can share the heat insulating layer, a structure layer and a waterproof layer with the building, the structure is simplified, the manufacture cost is decreased, and the work load of maintenance and repair is reduced. The ceramic solar energy roof constructed not only has all functions of the ordinary roof, but also can absorb the solar energy to be used to provide the summer air conditioning, the winter warm air, the living hot water, and when the area is enough big, the ceramic solar energy roof also can be used to generate electricity under a low temperature.
