Against the backdrop of Sudan’s Civil War, Mou Riiny, the founder of SunGate, fled with thousands of other South Sudanese boys to refugee camps in Kenya. Separated from their parents and uncertain of their fate, the boys often expressed, “Education is my mother and father.” For them, education was the only hope for a better future, should South Sudan ever achieve independence.
Years later, Mou and many others were relocated to the United States as part of the group known as the “Lost Boys of Sudan.” There, their dream of quality education became a reality. Many, including Mou, pursued higher education, with Mou eventually studying electrical engineering at the University of San Diego.
During his studies, Mou came across NASA’s global night sky map and noticed something striking—South Sudan was almost entirely dark. It became clear to him that energy was the missing link to progress. Without electricity, essential infrastructure such as hospitals, schools, and businesses could not thrive.

When South Sudan achieved independence around the time of his graduation, Mou faced a pivotal decision: remain in the U.S. or return to South Sudan to contribute to the nation’s growth. He chose to return.
With initial funding from IEEE ISV and clean energy investors, Mou founded SunGate with a clear vision: to empower self-reliance for the people and country of South Sudan and to lay the foundation for a prosperous future. By providing access to sustainable energy, SunGate aims to transform South Sudan’s narrative—from one of hardship to one of hope, from dependence to empowerment.

With South Sudan’s abundant solar resources and the declining cost of photovoltaic (PV) technology, solar energy offers the most viable solution for the country’s electrification. Recognizing that South Sudan’s scattered population requires decentralized solutions, SunGate provides hybrid solar systems tailored to the unique energy needs of households, businesses, and institutions across the country.

From small homes in remote villages to large urban centers, we create and implement solar energy systems suited to the specific needs of individuals and communities. Our commitment extends beyond just installation; we focus on providing solutions that enhance livelihoods and improve the quality of life in the communities we serve.

By delivering dependable, sustainable, and affordable energy, SunGate transforms obstacles into strength, propelling South Sudan’s journey toward self-reliance—one solar-powered solution at a time.

SunGate provides tailored solar energy solutions to meet the diverse needs of South Sudan’s households, businesses, and institutions.

Across all our solutions, we focus on maximizing the productive use of energy. We identify opportunities where solar power can drive socioeconomic development, improve community services, and enhance livelihoods—empowering South Sudan to thrive.
