Today the problems of energy insufficiency are getting more serious and turning a critical issue around the world. The trend of developing new energy in recent years has been undertaken for purpose of energy saving. Solar power is able to be utilized as a green renewable energy for its advantages of massive storage capacity, long-life and free from air pollution. Additionally, LED with strong functions such as higher illumination has greatly enhanced illuminative efficiency. Therefore, both solar power and LED are now two popular candidates for energy saving and carbon reduction. In this research we conducted the study with questionnaire survey by investigating regions of Ping-He elementary school in Nantou County and its proximate suburb. The data collected from the survey were analyzed using SPSS software. And we thus further analyses the feasibility of associating LED lamp with solar power for campus lighting on condition that the results were numerously supported by people. The final conclusion was drawn that if LED lamp and photovoltaic module are employed to substitute traditional fluorescent lamps available used in the school, the cost spent could be average down in the eleventh years.
