Determinants of household adoption of solar energy technology in Seychelles in a context of 100% access to electricity

Abstract

Seychelles is among four countries in the African continent with 100% access to electricity, of which over 90% of the energy is generated from fossil fuels. The energy transition is a crucial enabler of sustainable development and climate resilience. Therefore, this study seeks to understand the determinants of solar PV uptake based on a stratified random sample of 130 households on Mahe Island, Seychelles. We applied logistic regression and descriptive statistics to analyze the driving factors of a household decision regarding the adoption of a solar PV system. Results indicated that access to credit and monthly household income influenced the adoption of solar PV systems at the 1% significance level. Independent variables such as gender, age, and education of household heads, including family size that were significant in other studies, were not significant in the current study. Cost-saving (100%), energy security (91.7%), and environmentally friendly perceptions (76.7%), and access to loans (56.7%), were chief among the motivational drivers of the 60 households that had adopted solar PV systems. Whereas, for the non-adopters, the four most essential barriers cited were cheap electricity (82.9%), high initial cost (65.7%), existing loans (52.9%), and long payback time (40.0%). For the communal approach to solar PV systems in Seychelles to be successful, the adoption barriers that occur at the level of households should be considered.
