Technical & Economic Feasibility Evaluation of Using Various Battery Technologies In Stand Alone PV System For the Residential Sector In Yemen: Case Study

In Yemen, the lack of centralized power due to a collapsing power grid decimated by fighting, expensive commercial electricity, and skyrocketing diesel prices has forced a shift to solar power. As solar energy offers a cost-effective and environmentally friendly solution to the energy crisis, Stand-alone PV systems (SAPVs) are emerging as the primary energy source in Yemen. This paper presents the complete design of a SAPV system in different cases for a location in Ibb city, Yemen. The first case uses the lead-acid battery; the second uses the Lithium-ion battery to compare the economic feasibility. The system consists of multiple PV panels, inverters, batteries, and a charging controller. The “PVsyst” simulation software used analyzes the performance of the proposed SAPV system and anticipates the solar system's energy generation. As the performance of a photovoltaic (PV) system is affected by factors such as geographical location and the type of PV modules used, PVsyst also determines input data, losses considerations, system efficiency, and gross energy generation.
