Non-renewable energy depletion has prompted stakeholders to advocate alternatives, such
as solar energy to pursue sustainability. However, the acquisition rate of solar service is unconvincing
despite various initiatives; thus, we are seeking for a more focused remedy. This study is therefore
motivated to investigate elements influencing the intention to adopt solar energy, underpinned by
a unified theory of acceptance and use of technology. A self-administered questionnaire through a
purposive sampling method was employed, targeting working adults who own a home or intend
to purchase one in the future. Homeowners residing in condominiums, apartments, or any shared
building or property were excluded. Partial least squares structural equation modelling was used
for data analyses. Findings reveal that awareness positively influences performance expectancy,
effort expectancy, and facilitating condition. Additionally, performance expectancy and facilitating
conditions foster an intention to adopt solar energy. This research contributes pivotal insights into
solar energy purveyors to invoke awareness amongst Malaysia’s society while reiterating performance
expectancy, effort expectancy, and facilitating conditions towards solar energy adoption.
