Each year, millions of Americans experience energy insecurity, or the inability to afford enough energy to meet their basic needs. This study evaluates whether residential rooftop solar can serve as a preventative solution to energy insecurity among low- to moderate-income households. Using a national, matched sample of solar and non-solar households based on detailed and address-specific data, we find that solar leads to large, robust and salient reductions in five indicators of energy insecurity. Moreover, the benefits of solar {\textquoteleft}spill over{\textquoteright} to improve a household{\textquoteright}s ability to pay other energy bills. The results suggest that rooftop solar may be an effective tool for policymakers who seek to reduce energy insecurity.
