Impact of Relative Advantage, Perceived Behavioural Control and Perceived Ease of Use on Intention to Adopt with Solar Energy Technology in Sri Lanka

The acceptance and slow growth of solar energy is a major barrier in Sri Lanka. The aim of this study is to identify the impact of relative advantage, perceived behavioural control and perceived ease of use over intention to adopt with solar energy technology in Sri Lanka. Technology acceptance model (TAM), Diffusion of innovation (DOI) and Theory of planned behavior (TPB) are the theories that used to develop the research foundation. A self-administrated questionnaire was conducted to collect data from a sample of 384 respondent households. Structural Equation Modeling (SEM) was used to test the hypothesis. The result of the study indicates that relative advantage, perceived behavioural control and perceived ease of use have a positive impact with Solar Energy adoption. Providing financial support, obtaining continuous feedback and free technical advisory schemes will uplift the solar usage. Strategic planning to determine effective marketing activities to change customer’s intention will ensure sustainable business growth.
