US residential solar deployment moving towards less affluent households, says Berkeley Lab

March 3, 2022

Falling PV prices and expanded financing options have contributed to a rise in rooftop solar deployment among lower-income households in the US in recent years, a new report from Lawrence Berkeley National Laboratory (Berkeley Lab) has revealed.
