Development of a Rooftop PV Acceptance Model Among the Public in Indonesia and Employees of PT PLN (Persero)
Keywords:
Acceptance, PV rooftop, Renewable EnergyAbstract
The adoption of photovoltaic (PV) technology is vital for sustainable energy solutions, particularly in Indonesia's electricity sector. This study investigates the acceptance of rooftop PV systems among the general public and employees of PT PLN (Persero) using the Theory of Planned Behavior (TPB) framework. Data from 366 respondents (179 public, 187 employees) were analyzed through Partial Least Squares Structural Equation Modeling (PLS-SEM). Key findings reveal that the public’s adoption intention is significantly influenced by Subjective Norm (β = 0.212, p < 0.05) and Attitude (β = 0.463, p < 0.001), with economic incentives (β = 0.279, p < 0.001) and perceived benefits (β = 0.266, p < 0.001) playing a major role. Conversely, employees’ adoption intention is predominantly driven by Attitude (β = 0.689, p < 0.001), influenced by environmental benefits (β = 0.311, p < 0.001) and perceived incentives (β = 0.323, p < 0.001). The structural model explains 57.3% and 69.5% of the variance in adoption intention for public and employee groups, respectively. This study contributes to understanding adoption drivers and provides actionable recommendations for PT PLN, including targeted communication strategies, infrastructure enhancements, and cultural alignment initiatives to promote rooftop PV adoption.
