This paper examines the distribution of rooftop solar installations in Chicago and the factors that influence their adoption, with a particular focus on equity. Despite the many benefits of solar panels, including reduced energy costs and decreased greenhouse gas emissions, many households in the United States, especially those with low incomes and minority populations, face barriers to obtaining affordable solar electricity. The paper uses publicly available data sources and GIS software to map the distribution of building permits for solar panel installation in Chicago over time and compare them with community area income levels. The study finds that income levels have been a significant factor in the adoption of rooftop solar in Chicago, with solar panels initially clustered in high-income areas. However, policy easures implemented since 2016, such as The Future Energy Jobs Act and Illinois Solar for All, have been effective in increasing equitable adoption, although penetration rates remain low in very low-income populations. The analysis demonstrates the importance of policy that aims to increase the equitable adoption of solar panels, especially for disadvantaged communities, and provides insights for policymakers and stakeholders interested in promoting solar energy adoption in urban areas.
