Low- and moderate-income (LMI) households are less likely to adopt rooftop solar photovoltaics (PVs) than higher-income households in the United States. As the existing literature has shown, this dynamic can decelerate rooftop PV deployment and has potential energy justice implications, in light of the cost-shifting between PV and non-PV households that can occur under typical rate structures and incentive programmes. Here we show that some state policy interventions and business models have expanded PV adoption among LMI households. We find evidence that LMI-specific financial incentives, PV leasing and property-assessed financing have increased the diffusion of PV adoption among LMI households in existing markets and have driven more installations into previously underserved low-income communities. By shifting deployment patterns, we posit that these interventions could catalyse peer effects to increase PV adoption in low-income communities even among households that do not directly benefit from the interventions.

政策和商业模式对采用屋顶太阳能的收入公平的影响

与美国的高收入家庭相比,中低收入(LMI)家庭采用屋顶太阳能光伏(PVs)的可能性较小。正如现有文献所表明的那样,鉴于在典型的费率结构和激励计划下可能发生的光伏家庭和非光伏家庭之间的成本转移,这种动态可能会降低屋顶光伏的部署,并可能对能源正义产生影响。在这里,我们表明,一些州的政策干预措施和商业模式已在LMI家庭中扩大了PV的采用。我们发现有证据表明,针对LMI的特定财务激励措施,PV租赁和财产评估融资已提高了PV在现有市场中LMI家庭中的普及程度,并推动了更多向以前服务欠缺的低收入社区提供安装服务。通过改变部署模式,
