Factors Affecting the Consumers’ Energy-Conserving Behaviours on Solar-Plus-Storage (SPS) Systems’ Adoption for Sustainable Electricity Consumption: A Case in Malaysia

This study identifies and explores the key factors influencing the Malaysian public’s energy-conserving behaviors from adopting Solar-Plus-Storage (SPS) technology and their roles as mediators towards sustainable electricity consumption. A cross-sectional survey was used to collect quantitative data to statistically test the hypotheses in this explanatory research. Partial Least Squares Structural Equation Modelling with SPSS and SmartPLS software was used to examine data from 188 responses received. The results of the direct effects indicate the significant influence of the behavioral, technical, and environmental factors on consumers’ energy-conserving behaviors, consumers’ energy-conserving behaviors on sustainable electricity consumption, and the behavioral, technical, and environmental factors on sustainable electricity consumption. Meanwhile, the results of the mediation effects reveal that consumers’ energy-conserving behaviors mediated the influence of behavioral, financial, and environmental factors on sustainable electricity consumption. The findings can pave the way for policymakers to recognize the affordable prices of batteries and solar panels can accelerate the market uptake of the Solar-Plus-Storage system. Future studies should consider the impact of consumer environmental awareness from technology usage and explore more variables that affect consumers’ energy-conserving behaviours.
