Message from Chief Executive Officer

Mou Riiny

Mou Riiny left South Sudan as a young man during the Civil War and was fortunate to study electrical engineering at the University of San Diego. In his studies, he remembers seeing a map of the world at night. Seeing the darkness over South Sudan inspired him to want to develop solutions for energy access in South Sudan. Following a senior project focused on designing solar energy systems in remote areas, he moved back to South Sudan in 2012, and in 2013 with funding support from the Institute of Electrical and Electronics Engineers (IEEE) and clean energy investors, Mou launched SunGate Solar. From these humble beginnings, Mou has now grown SunGate to have over 65 staff, 200+ projects, and 2 mw+ of solar online in 13 states providing clean, reliable, affordable solar solutions to thousands of people across South Sudan. SunGate Solar’s core business is designing and installing off-grid solar power systems, but in 2023, opened the very first solar-powered Utility-scale project in South Sudan and is now working to scale the model to other towns.
