The adoption of solar photovoltaic technology on a residential scale has been encouraged in several countries, including Brazil, however, little is known about the standards and determinants of the adoption of this technology in the context of developing countries. In this sense, the present study intends to fill this gap, seeking to identify the determinants of the adoption of residential photovoltaic solar technology in Brazil. The population studied in the present study consisted of 123,552 units of residential photovoltaic systems, adopted (and installed) over the period from January 2014 to December 2019 and per federation unit, according to the database of grants and registrations of Distributed Generation of the National Electric Energy Agency. The methodological approach used is quantitative, with longitudinal cut, statistical treatment of the data and makes use of a longitudinal model of negative binomial nonlinear regression with fixed effects. It was identified that the factors average electricity tariff, average monthly electricity consumption of families and existing incentives have a positive impact on the adoption of residential photovoltaic systems by families. And of the socioeconomic variables related to each unit of the federation, only the housing density has a positive impact on the adoption of residential photovoltaic systems, while the unemployment rate was not statistically significant and the per capita household income has a negative influence on the adoption. In addition, the results suggest that the adoption rate of this technology does not necessarily follow the spatial patterns of population and income distribution. The results obtained also suggest that, in the Brazilian context, families seek to install residential photovoltaic systems in order to reduce their monthly electricity bills. However, the negative impact of per capita household income and the positive effect of incentives indicate that the latter are necessary to increase the adoption rate of this technology in the country. |
