Senegalese-based Solar Pay-As-You-Go startup, Oolu, has raised $8.5million in Series B round led by RP Global, an independent renewable energy developer. Other participating investors included Persistent Energy Capital, Shell-seeded impact investor All On, Gaia Impact Fund, and DPI Energy Ventures. The Y Combinator start-up raised $3.2 million in a Series A round in 2017.
Oolu intends to use the new funds to expand its core product offering to meet the needs of its current and future customers and further develop its operations in West Africa.
Founded in 2015 by Nilmi Senaratna and Daniel Rosa, Oolu is a for-profit, social impact company operating in five West African countries: Nigeria, Senegal, Mali, Burkina Faso, and Niger.
To date, Oolu has sold over 60,000 solar home systems and built a proprietary management platform and distribution network

Dan Rosa, CEO and co-founder of Oolu, said: “The strength of our business and industry during a challenging global pandemic has demonstrated the value that customers see in our products and service. RP Global’s financial expertise and experience in managing renewable energy businesses will enable us to accelerate our growth. All On’s unparalleled knowledge of the renewable energy sector in Nigeria will help us to further adapt our business to meet customers’ needs. In addition, we are excited to continue our successful collaboration with current investors especially Persistent.”
Leo Schiefermueller, Director of RP Global Africa, comments: “We are looking forward to working with the most promising solar home systems provider in West Africa. Having found a partner with such an efficient structure and excellent management, makes us optimistic that this will be our greatest venture in Africa to date. The fantastic team at Oolu is prepared to lead the company towards a whole new level of success and growth in all areas of one of Africa’s most important challenges – ‘access to energy’.”
All On Investment Manager, Afolabi Akinrogunde added: “Oolu Solar’s operational expertise, geographical spread in West Africa, flexibility and efficiency has earned the company a leadership position in solar home systems distribution. Their success across the region and Nigeria gives All On the confidence that this investment will further enhance our commitment to enabling the deployment of affordable off- grid power solutions in the Niger Delta and Nigeria as a whole.”
