All-ceramic solar collector and all-ceramic solar roof

A type of all-ceramic solar collector is introduced. These all-ceramic solar collectors are made from ceramics. The material of absorber coating is V–Ti black ceramic. The solar absorptance of absorber coatings with a reticular formation is in the range of 0.93–0.97, without the attenuation of solar absorptance. The fluid passages are integrated with the absorber plate, which naturally formed in the process of shaping. The integration between fluid passage and absorber plate is good to transfer heat from the absorber plate to the fluid. The thermal efficiency of all-ceramic solar system is more than 50%. The all-ceramic solar system can integrate well with building roof. All-ceramic collector and system are characterized by low cost and long lifetime. Such characteristics reduce the cost of solar energy utilization.
