The Solar Electric Light Fund has successfully deployed water irrigation pumps powered by PV panels in Benin. The sustainable systems are expected to be cost-advantageous after 2.3 years compared to gasoline or diesel engines (SELF, 2011). Four main segments of the private sector that can play a leading role in improving access to electricity have been identified: large multinational manufacturers (vendors), utilities/ESCOs, local private companies (community-based), and NGOs.
