Analysis of predictors for the implementation of residential photovoltaic solar systems in Vale do Paraíba

Abstract

Photovoltaic energy is one of the main energy sources for the transition from non-renewable to renewable energy generation. However, in Vale do Paraíba (São Paulo, Brazil), despite the favorable conditions for implementing distributed generation of photovoltaic energy, the installed capacity is much lower than the existing generation potential, showing the factors that hinder a more substantial implementation and diffusion of this technology. Therefore, the focus of this study is to identify predictors that indicate the intention to apply photovoltaic solar systems in Vale do Paraíba. The information was collected through an online questionnaire (n = 168). The data collected are related to socioeconomic characterization, indicators of conscious consumption, subjective and objective knowledge, and perception. The results indicate the respondents’ belief that it is expensive to install photovoltaic panels. However, they also believe that the investment is worthwhile. Furthermore, dependence on subjective and objective knowledge was observed (p <0.05), indicating that those who claimed to know the solar photovoltaic system by distributed generation performed better when answering technical questions about the technology. Finally, gender, age group and perception are associated with the intention to apply photovoltaic panels.
