The Honnold Foundation Core Grant Program funds community-driven solar energy projects that advance energy access, equity, and environmental sustainability in marginalized communities. Grants ranging from USD 25,000 to 150,000 support locally led organizations—particularly Indigenous-, Black-led, and women-led groups—working in the Americas, Cambodia, and climate-vulnerable island nations.
The program prioritizes projects that build or improve solar infrastructure with strong community participation and long-term social impact.
Funding Community-Driven Solar Energy Solutions for Equity and Climate Impact
The Honnold Foundation supports grassroots and community-connected organizations that are expanding access to clean, renewable solar energy while promoting social and economic equity.
Its grantmaking focuses on projects that directly benefit marginalized communities, reduce reliance on polluting energy sources, and strengthen local capacity to manage and sustain solar infrastructure.
