The Water and Energy 4 Life Plus (WE4L+) initiative was designed to bring reliable energy solutions to off-grid schools and health clinics in Ethiopia through stand-alone solar PV systems and solar mini-grids. To maximize system performance and ensure energy sustainability, a comprehensive energy audit will be conducted across multiple sites, encompassing various system capacities and energy demands. This audit will assess the current performance of the solar systems, identify inefficiencies, and recommend technical improvements to optimize energy generation, distribution, and storage.
