SOLAR ENERGY & ENERGY STORAGE SYSTEM FOR A 20-HOUSE COMMUNITY IN ACCRA, GHANA

Abstract: A renewable energy and energy storage system is designed for a project of 20 upscale houses to be constructed in Accra, Ghana is the Swedish start-up company of AsaDuru. Renewable energy generation and storage methods are investigated and the suitable types of generation methods and the components which shall be used in these are decided. Detailed information about the target project site is attained through a visit funded by a Minor Field Studies scholarship, and a comprehensive economic analysis based on local conditions is made. It is found that a solar energy system using poly-crystalline modules, lithium-ion batteries and a generator back-up would be the most suitable system design for this project, and the only way to fulfill economic criteria. A renewable energy fraction of 98% is achieved at a cost level of 26 740$/house, roughly 10% lower than the set upper limit of 30 000$.
