From Idea to Impact: Engineering KeepTheSun, an Innovative Circular Startup delivering Energy Access

This thesis explores the creation, development, and potential impact of Juakit, an innovative off-grid solar solution by KeepTheSun, a circular startup that repurposes second-life photovoltaic (PV) panels to address global energy poverty. In collaboration with Coesa S.r.l., the project evolves from a European digital marketplace for used solar panels into a tangible product aimed at providing affordable, reliable, and clean energy to underserved communities in Sub-Saharan Africa. Central to this research is the development of Juakit, a modular, portable solar kit designed to meet the energy needs of households, schools, health centers, and small businesses in off-grid settings. The study emphasizes the circular economy model, focusing on the reuse of decommissioned solar panels sourced from Europe. By utilizing second-life panels, Juakit offers an environmentally sustainable and economically feasible solution to energy access in Sub-Saharan Africa, where over 660 million people still lack reliable electricity. The thesis adopts a multi-disciplinary approach, integrating management engineering principles with practical project development. Key aspects of the research include the creation of a scalable business model, with a strong focus on affordability, technical challenges in rural deployments, and the role of financing models like Pay-As-You-Go (PAYG). The study provides a detailed economic and financial business plan, including a SWOT analysis, risk mitigation strategies, and a financial forecast showing the project’s potential for profitability and sustainability by 2028. A key component of the research is the pilot project in Uganda, designed to test Juakit in real-world conditions. Preliminary findings suggest that Juakit can improve economic resilience by providing essential services such as milk refrigeration, reducing spoilage, and increasing farmer income. The thesis concludes with a discussion of future challenges and the scalability of Juakit across other regions in Sub-Saharan Africa. It highlights the importance of integrating financial viability with social inclusivity and environmental sustainability to create innovative, scalable solutions to global challenges like energy poverty. The research offers valuable insights for policymakers, impact investors, and entrepreneurs focused on implementing Sustainable Development Goals (SDGs) through impact-driven solutions in renewable energy.
