High-income households are more likely to adopt rooftop solar photovoltaics (PV) than low-and moderate-income (LMI) households in the United States. Income-skewed adoption persists even as PV becomes more affordable and financially beneficial to LMI households. PV adoption inequity is an emerging energy justice issue, particularly considering that income-skewed deployment could increase LMI household electricity bills under typical rate structures. Further, PV adoption inequity could decelerate rooftop PV deployment. Here we show that policy and business model interventions could increase PV adoption equity. We find that LMI-specific financial incentives, PV leasing, and propertyassessed financing increase PV adoption equity. We find that these interventions increase equity in existing markets and drive more installations into previously under-served markets with lower incomes. By shifting deployment patterns, these interventions could also catalyze peer effects and installer marketing efforts that increase LMI adoption among households that do not directly benefit from the interventions.
