Our Impact

Solar Sister entrepreneurs create a ripple effect impacting local women, their families, and the customers and communities who switch to using clean energy. Find out more about our data-driven approach and how we measure impact.

Independent research shows that Solar Sister’s model improves not only a woman’s household income, but also health, education and a woman’s status and control over resources.

Income allows women to contribute to household earnings and gain confidence, financial independence, and respect from their families. Women entrepreneurs start to play a larger role in household decision-making. Training and ongoing mentoring equip entrepreneurs with important skills like financial management and technical product knowledge. As a result, women gain confidence and often serve as role models and change agents in their communities.

Families benefit from better health and economic stability thanks to use of clean cookstoves and solar light. Children have reliable, bright lighting to study by at night. Women in particular benefit from time savings thanks to increased lighting after dark and those who use solar lights report increased productivity after the sun sets. Families who switch to clean cookstoves significantly reduce time spent collecting wood, money spent on solid fuels, and smoke output, significantly improving the health of women and children.
