Abstract
This study develops a comprehensive framework for the establishment of a solar farm at Nile University, Nigeria, to address the institution’s energy needs through a sustainable system. The research employs a mixed-methods approach, combining quantitative energy cost analysis with qualitative data gathered from staff responsible for the operation and maintenance of the solar farm. The energy cost analysis compares diesel, Abuja Electricity Distribution Company electricity (AEDC), and solar energy, revealing significant cost savings with solar energy. In October 2024, the total expenditure for solar energy was ₦2,742,591.6, much lower than diesel (₦86,265,556) and AEDC electricity (₦34,308,120). The study also evaluates the environmental benefits of reduced carbon emissions, reduced reliance on fossil fuels, and alignment with global sustainability goals. The findings highlight the economic feasibility of the solar farm, suggesting substantial long-term savings and a positive return on investment (ROI) despite the substantial initial cost. The study recommends the implementation of the solar farm project, emphasizing its long-term financial, operational, and environmental advantages for Nile University. This framework serves as a model for other Nigerian institutions and can contribute to the broader adoption of renewable energy solutions across educational facilities.
