unlocking widespread solar adoption

Uptake of rooftop solar has primarily been concentrated in higher income households. As technology costs decline, focus is shifting toward increasing uptake in underserved market segments. A key policy goal is to expand solar access more equitably, particularly to low-to-moderate income (LMI) households. In order to achieve this goal, a deeper understanding of the potential LMI market is needed.

 

This four-year project used data-driven and evidence-based methods to identify characteristics, motivations, and barriers specific to LMI solar demand. These activities included:

  • Mapping the technical potential for solar deployment in LMI communities

  • Conducting three case studies to examine the pertinent economic and policy factors that contribute to or hinder LMI market potential

  • Surveying LMI adopter households to understand attitudes and beliefs about solar

  • Testing strategies to increase customer referrals among LMI households
