Abstract:

Lithium-ion batteries have captured the attention of researchers in renewable energy because of their advantages over the other types. This study studied the power capacity variation of a lithium-ion battery when installed with solar panels for home appliances to improve the users’ experience. An experiment was conducted for five months (November to March). The study discovered that the lithium-ion battery’s power capacity was reasonably stable (or uniform) on some days but was also characterized by very significant variations on others. The theoretical maximum power, P_(max,th). from the battery bank was 10.08kW, but the experimental maximum power,〖 P〗_(max,exp).was 9.864kW. Also, the maximum theoretical energy, E_(max,th,) from the battery bank was 80.64kWh,and the experimental maximum energy capacity generated from the battery bank, E_(max,exp). was 78.912 kWh. The slight power capacity variation was attributed to the solar panel’s usage and efficiency, which is sometimes affected by cloudy or hazy weather. 

Keywords: Power Capacity; Variation of Lithium-Ion Battery; Energy and Efficiency; Sustainable Energy; Renewable Resources; Hazy Weather; Photovoltaic Systems.
