| Summary/Abstract |
The rapid growth of distributed solar adoption in California provides an opportunity to lower electricity bills for the adopters and realize additional community benefits, including grid resilience and lower grid emissions. It is unclear, however, whether this transition is occurring equitably across the state's various demographic and socioeconomic groups and whether historically disadvantaged environmental justice (EJ) communities have been able to exploit the bill savings and other associated benefits of rooftop solar. Here we analyze the cumulative and annualized (spatial and temporal) rates of PV adoption across California and compare those with data from the state's cumulative impact EJ methodology (CalEnviroScreen). We find persistently lower levels of PV adoption in disadvantaged communities, suggesting clear distributive and equity impacts of existing PV support policies, and indicating that the benefits bypass some of the state's most vulnerable populations. The analysis reveals strong correlation of solar adoption with not only socioeconomic variables, but also with health, environmental and demographic indicators, contributing to our growing understanding of the role these factors play in household clean-energy adoption trends. The results provide a baseline from which to develop more effective policies, strategically design incentives, and track the efficacy of existing solar programs that target disadvantaged communities.

| Summary/Abstract |
Financial incentives for rooftop solar photovoltaic (PV) adoption have declined in the United States over time by policy design. Incentive phase-down can efficiently promote early adoption and avoid ineffective payments to late adopters. However, incentive phase-down may exclude low- and moderate-income (LMI) households from realizing the same financial benefits from PV adoption as high-income early adopters. Here, data from two state-level LMI PV incentive programs are analyzed to test whether incentives still drive PV adoption among LMI households. As a first order approximation, the analysis suggests that incentives drove adoption that would not otherwise have happened in about 80% of cases. To the extent that policymakers prioritize PV adoption equity as part of the emerging energy justice policy agenda, the results suggest that ongoing incentive support for LMI adoption may be merited.

| Summary/Abstract |
Delhi's rooftop solar (RTS) policy was announced in 2016, but RTS has not been adopted as much in the residential segment as it has been in the other segments like commercial and industrial establishments. This not only makes it difficult for the government to achieve its RTS targets but also raises energy justice concerns as it deprives a large section of the population from benefitting from RTS. Residential consumer segment in Delhi is quite heterogeneous consisting of sections that differ widely with respect to income, roof space, education and technological awareness. Thus, an effective dissemination strategy for RTS in Delhi would require customized interventions, suiting the requirements of these different sections of the residential segment. In this paper, we provide some suggestions for such interventions. The study shows that for an extensive RTS dissemination in Delhi, policy makers have to adopt a holistic approach and simultaneously address the financial, political, regulatory, social and psychological barriers.

| Summary/Abstract |
The threat of climate change has necessitated that nations make a switch to greener and more environmentally sustainable fuels. India's plans to promote electricity generation from solar energy is a positive step in this direction. Several states have come up with their own renewable energy plans to support this transition. Delhi's solar policy (2016) intends to contribute to this national plan. It was widely believed that Delhi's favourable geographical conditions for solar, relatively high literacy rate and good public awareness would aid good market penetration of rooftop solar (RTS). However, the expectations of the policy makers have been belied by a meagre adoption rate as RTS has met with a very lukewarm response from the residents of Delhi. The current study holistically explores the obstacles hindering the growth of Delhi's RTS market by integrating perspectives from solar vendors, implementing agencies' officials and users/potential users and suggests some policy measures to address the issues.
