Solar energy, including household and community based solar photovoltaic panels, is the fastest growing source of low-carbon electricity worldwide, and it could become the single largest source of renewable energy by mid-century. But what negative equity and justice issues may be associated with its adoption? What risks are being accelerated as solar energy grows exponentially in its deployment? In this study, we rely on a mixed methods research design involving household solar interviews (N = 24), site visits (N = 4 solar neighbourhoods), and a literature review to investigate four types of inequities associated with household solar adoption. We utilize a novel framework looking at demographic inequities (between groups), spatial inequities (across geographic scales), interspecies inequities (between humans and non-humans), and temporal inequities (across present and future generations). This framework enables not only the identification of multiple and often interlinked inequities; it also points the way towards how to make solar energy adoption more sustainable and just, with direct implications for solar business practices (and supply chains) as well as energy and climate policy.
