"Solar Sister, a social enterprise operating in Tanzania, Uganda, and Nigeria, is dedicated to eradicating energy poverty through the economic empowerment of women. In addition to economically empowering its women entrepreneurs, the business model of Solar Sister also cultivates sales networks built on trust in last-mile distribution methods. While Solar Sister has previously conducted research regarding its many entrepreneurs, it has lacked information on its end customers. In 2016 a research team from Santa Clara University’s Miller Center for Social Entrepreneurship undertook survey research with Solar Sister to examine the effects of solar lantern use on users’ health, education, time allocation, household savings, income generation, and increased agency. The research team conducted a 53-question survey in more than 20 villages across five regions in Tanzania, with research assistants providing English-Swahili translation. The data and stories presented here are intended to help illuminate the potential of solar lanterns to improve livelihoods in rural Tanzania and beyond."
