Abstract:
This research aimed to study 1) the importance level of attitude, reference group conformity, perceived usefulness, perceived ease of use, and intention to use solar power generation system in industrial factories in Chiang Mai province; and 2) to study attitude, reference group conformity, perceived usefulness, perceived ease of use that affect intention to use solar power generation system in industrial factories in Chiang Mai Province. The population and sample were 385 industrial factories in Chiang Mai Province that intended to use solar power generation system; this was survey research. The research instrument was a questionnaire, using descriptive statistics to analyze Percentage, Mean, and Standard Deviation, and Inferential Statistics to analyze multiple regression with the technique of Enter Selection.
