Africa has a huge untapped solar potential, and at the same time, the importance of off-grid solar power supply and applications is significant on a continent where electrification is still a major challenge for states and governments. At the same time, decentralized solar power generation can contribute not only to electricity supply, but also to addressing other critical development issues. The integrated solar water desalination project at Lodwar Hospital in Kenya, implemented by Boreal Light GmbH and supported by the German Development Cooperation through the develoPPP.de program, is a flagship project that contributes to several Sustainable Development Goals.
