With the rise of global environmental awareness and the global shock brought about by the Fukushima nuclear disaster, the green energy industry is increasingly valued by various countries. The Taiwan government has also vigorously promoted the green energy industry in recent years. Among them, solar power generation has spring up, so this study will using data mining technology, the three types of cases of water surface type, ground type and roof type are classified and analyzed. In addition, the actual cases built in different regions of Taiwan are used for cluster analysis based on the data of their power generation status. Hopefully I can find useful associations and relationships and sort out effective information to provide a reference for the establishment of Taiwan's subsequent development of solar power generation cases.
