The utility model discloses a solar energy bamboo prefabricated house. A load-bearing member of a prefabricated house is processed by bamboo raw materials; a load-bearing and heat-conducting composite wall body is made by a bamboo supporting column and a bamboo board; and a solar heat collector is also provided so as to manufacture part or all of bamboos in the bamboo prefabricated house into a heat-conducting component. The load-bearing member formed by the bamboo and the composite wall body of a closure material are modularized and serialized, and are prefabricated in a factory. Part or all of bamboo tubes in the load-bearing member and the load-bearing and heat-conducting composite wall body are excavated to form a plurality of hot air passages coming from the solar heat collector; nodes in the load-bearing member are reinforced and connected by a metal connecting piece; and anti-cracking hoops are arranged above and below the bamboo nodes. The solar energy bamboo prefabricated house provides a new solution to formation and improvement of the novel low-carbon building technology system and low-carbon bamboo house manufacturing technologies in the modern building field of China.
