This research aims to study solar energy applications in floating hotels. In order to achieve this aim, the current research adopted a deductive approach using the personal interviews with managers who are working in floating hotels in Luxor and Aswan sample of the research and with engineers who working in solar energy companies. A total of 52 personal interviews were conducted with the manager's which represent sample of the research. The findings of the filed study showed that the level of awareness of managers with solar energy applications is poor and there is no strategic vision from hotel management of using solar energy applications. The results also showed that the high prices of solar technology and the lack of space needed to place solar cells on floating hotels are considered the main obstacles for the use of solar energy applications.
