Dunia ya Heri's four solar fields are a prime example of sustainable energy provision in Africa. Thanks to the year-round strong sunlight near the equator, the photovoltaic systems can provide a largely independent power supply. The storage capacity ensures there is enough energy even in the rainy season. A separate PV system, installed by Polish friends, powers the new dining hall. The solar installations are an important pillar of Dunia ya Heri's sought-after self-sufficiency and a practical example of environmental awareness. The children learn about the importance of renewable energy and its contribution to climate protection. The solar system stands for independence, sustainability and a responsible future.
