Solar Sister sold clean energy through women's own networks
Solar Sister trains women entrepreneurs to sell solar products in their communities, making women the last-mile distribution channel.
Solar Sister
the move
In sub-Saharan Africa, 600 million people lacked access to electricity in 2019 and 900 million cooked with traditional fuels, yet solar products' adoption rates stayed modest and distribution strategies ineffective.
Katherine Lucey founded Solar Sister to fix the distribution problem: rather than building stores, the organization recruits and trains women entrepreneurs to sell clean-energy products in their own communities, turning trust and social networks into the sales channel.
The CASE Journal case study documents how the model simultaneously addresses energy access and women's economic empowerment, using women's roles as household decision-makers to make solar products reach last-mile homes that conventional retail misses.
why it works
- Community trust travels faster than a store can be built.
- Women entrepreneurs know their neighbors' needs and payment realities.
- Training local sellers creates income in the same communities the products serve.
- Door-to-door selling overcomes the last-mile cost that kills retail chains.
what transfers
When the target customer trusts a neighbor more than a store, build your distribution from neighbors: train local sellers and let social networks carry the product.
what came after
Solar Sister grew into a network of thousands of women entrepreneurs across sub-Saharan Africa, combining energy access with women's economic empowerment and becoming a reference case for social-enterprise distribution.
