How Solar Sister Is Solving Energy Poverty in Africa Through Women Entrepreneurs

What is the problem?
In Africa, more than 300 million women don’t have access to reliable electricity, a major obstacle to improving health, education, and economic prospects in rural Africa. In rural Nigeria, Tanzania, and Kenya, people cook with stoves that emit poisonous fumes in their homes; children learn in poorly lit kerosene environments that hurt their eyes, and businesses shut down early because there is no light.
The costs are enormous. But the problem is not technology. Multinational solar firms have created good products, but they can’t reach the last mile due to poor infrastructure. In these areas, money is scarce, and customers don’t trust unfamiliar sales representatives whom they’ll probably never see again.
Even in villages where solar products exist, women don’t have enough money, credit, or decision-making authority to purchase them.
What is the solution?
Solar Sister trains African women entrepreneurs in rural areas to fight energy poverty in their communities. Each recruit receives a “Business in a Bag” kit, consisting of solar lanterns, solar home systems, phone chargers, and clean cookstoves, along with training in sales, bookkeeping, and customer service.
Women then sell these kits to people in their community. Solar Sister addresses two challenges at once: customers receive energy from a reliable source they already trust, while the women who sell earn an independent income and increase their status within their community. Solar Sister also has a network of Business Development Associates who mentor, train, and assist entrepreneurs and help them troubleshoot problems in the field.
What is the business model?
Solar Sister operates as a social enterprise and a nonprofit, using a hybrid business model to generate revenue. According to its annual report, funding sources include grants (about 47%), donations (about 15%), product sales (about 32%), and other sources (about 4%). Solar Sister Entrepreneurs receive a percentage of each product sold, so their income depends on sales volume.
Solar Sister imports its products from certified producers that meet World Bank Lighting Global standards. The organization deliberately chooses not to push its Business Development Associates to generate revenue, so that mentorship stays focused on impact rather than commissions. This creates a structural tension every social enterprise faces: how to balance mission with the financial sustainability that keeps the mission alive.
Who founded Solar Sister?
Katherine Lucey, a former investment banker, founded Solar Sister in 2010 after visiting rural Africa and seeing women cooking over open fires and children studying by kerosene light. Lucey started with ten women entrepreneurs from Uganda. Today, Solar Sister operates in Nigeria, Tanzania, and Kenya, and previously operated in Uganda, Rwanda, and South Sudan.
In September 2025, Solar Sister entered into a partnership with Koolboks, an off-grid refrigeration company, under which the organization pledged to equip 1,000 women entrepreneurs with solar refrigeration technology in Nigeria, Kenya, and Tanzania by 2028.
Why is it innovative?
In Africa, the most common last-mile distribution systems employ salespeople and send them into villages. Solar Sister is different from those models. Instead of recruiting and employing salespeople, Solar Sister recruits local women and teaches them how to build their own businesses. Not only does this solve the long-standing trust issue in rural product distribution, but it also creates a multiplying effect. All Solar Sister entrepreneurs become role models for other women and lower the cultural barrier to entering the business for future women.
The organization tracks impact carefully: every dollar invested in a Solar Sister Entrepreneur generates approximately $48 in economic benefits in the first year alone, split between the entrepreneur's earned income and her customers' savings on kerosene, batteries, and mobile charging fees. A single $18 solar lantern saves a customer roughly $163 over five years compared to kerosene.
What is the impact?
Trained over 12,500 Solar Sister Entrepreneurs across Nigeria, Tanzania, and Kenya
Reached 5.9 million people with clean energy products
Generated approximately $231 million in economic benefits in off-grid communities
Mitigated approximately 2.2 million metric tons of CO2 equivalent emissions
What needs to improve?
The first challenge is that about 60% of the company's revenue comes from grants and donations. There is always a risk that shifts in the donor community's priorities or cuts in institutional giving could jeopardize Solar Sister's survival.
The second structural barrier is low smartphone penetration among Solar Sister Entrepreneurs. On the one hand, this means Solar Sister Entrepreneurs are serving disadvantaged women; but on the other hand, it limits the digital solutions that can integrate into Solar Sister operations.
Finally, scaling in rural Africa is slow because of poor roads, inconsistent cash flow, and the need to build relationships over time. However, Solar Sister has been operating for 15 years and has engaged 11,000 entrepreneurs. Nevertheless, this remains relatively insignificant, given that 300 million women in Africa still lack access to electricity.
Growing the entrepreneur network into the tens of thousands, and eventually the hundreds of thousands, will require capital, new country expansions, and product innovations similar to the Koolboks refrigeration partnership that push beyond lighting into productive-use energy.
