ABSTRACTThe rising worldwide energy demand and the pursuit of sustainable development have resulted in the use of solar photovoltaic (PV) technology as a viable alternative. Developing nations, facing various challenges and ambitions, are at a critical crossroads where the adoption of solar photovoltaic technology might instigate significant transformation. This study examines the implementation of solar photovoltaics in developing nations, focussing on the associated problems and potential. This study examines the status of solar photovoltaic technology, the challenges it faces in developing nations, and the potential opportunities and uses. Developing countries are poised for a significant opportunity in the shift to sustainable energy. International assistance, encompassing loans, grants, technical support, and collaborative partnerships, serves as a beacon of hope, igniting the impetus necessary to promote the use of solar photovoltaic (PV) technology. The essential function of international collaboration in advancing solar energy deployment, based on case studies that illustrate the capacity for cooperative initiatives to accelerate development and foster a cleaner, more equitable energy landscape. Nigeria energy landscape is unpredictable and unreliable and so the deployment of renewable energy can ensure constant energy supply. Tanzania exemplifies how the desire for energy solutions may stimulate innovation. Haiti, a nation grappling with energy poverty, exemplifies the necessity of international collaboration for sustainable development. The Solar Market Gardens initiative was initiated by the Solar Electric Light Fund (SELF) in partnership with local organisations and international financiers. This initiative enhanced agricultural output in Nigeria.
