Abstract

The objective of this research endeavor is to examine the attitudes and intentions of householders in the Philippines with respect to the implementation of Residential Rooftop Solar Photovoltaic Systems (RSPVS) and the subsequent adoption of this renewable energy technology. The research is motivated by favorable circumstances in the Philippines, which encompass abundant irradiance, favorable policies regarding solar photovoltaics, and declining expenses for systems. Gaining insight into the viewpoints of prosumers (consumers and producers) is essential for expediting the implementation of RSPVS, thereby facilitating the increased utilization of solar energy. Expanding upon prior investigations that underscore householders' profound fascination with solar technology despite significant obstacles such as exorbitant installation expenses and a dearth of comprehension, the present study endeavors to illuminate the determinants that impact prosumers' intentions to utilize RSPVS. By integrating Technophilia and Perceived Risk as supplementary constructs and utilizing a conceptual framework that combines the Technology Acceptance Model (TAM), Theory of Planned Behavior (TPB), and Unified Theory of Acceptance and Use of Technology (UTAUT), this research endeavors to identify the factors that promote or hinder the adoption of RSPVS. The research utilizes an online survey that was disseminated in prominent urban areas where Residential RSPVS is accessible. The sample consists of 239 participants, which satisfies the minimum sample size requirements. In addition to demographic information (e.g., gender, age, education, income, and sources of solar PV data), the questionnaire inquires about constructs associated with the adoption of RSPVS as outlined in TAM, TPB, and UTAUT. Using Partial Least Squares Structural Equation Modeling (PLS-SEM), the collected data are analyzed to determine the hypothesized model and to examine the relationships between variables. Technophilia, Price Value, and Social Influence are significant predictors of prosumers' intent to adopt MRSPVS, according to the findings. Significantly, Technophilia, which denotes a profound interest in novel technologies, surfaced as a crucial determinant, indicating that prosumers are driven by the appeal of solar energy. Furthermore, the research determined that Perceived Risk did not serve as a substantial impediment.
