The declining cost of solar energy is creating opportunities for all Americans to save money on their energy bills. And no one benefits from energy savings more than low income consumers, who pay a much higher portion of their income for energy than middle and high-income consumers. But being poor creates barriers to accessing solar power and its economic benefits. Low income consumers lack sufficient savings that can be used to buy solar systems, and they may have low credit scores or a lack of credit history that may impede their ability to finance a system. They are often renters, or live in multifamily housing, without ownership of their roof. Policymakers have been trying a range of approaches to bring solar to low-income consumers. This guide surveys the field and recent studies to give a sense of what is being tried, and what could be tried. It examines what has and hasn’t been working, and what factors determine whether a given policy or program might work in a given circumstance.
