The vehicle powered by the solar energy is expected to be clean and to make energy savings. In this report, the solar thermal collecting system, which collects the solar energy from the sunlight as power source of the vehicle and uses Evacuated Double Glass Tubular Collectors with selection-absorption film, was tested to evaluate the characteristics of the collecting the solar energy. The test results present that the solar thermal collecting system needs to improve the construction and the efficiency and clarify the route of heat rejection from the tubes.
