Most standalone Solar Photovoltaic (PV) systems in Nigeria are of the fixed standalone type and are fixed either on the roof of a building, at the top of an iron pole or other unmovable positions and so, do not produce required maximum energy conversion due to the varying movement of the sun in the sky. Recent studies have shown that the amount of electric power generated by PV arrays varies continuously with weather conditions. Even under clear weather conditions, the position of the sun changes during the day, which in the case of fixed installed solar panels leads to changes in the effective surface of the solar panels towards the sun and a decreased output power. At present, PV energy conversion efficiency stands at between 9% and 18% depending on the solar cells used, especially in low irradiation conditions. For any PV system, therefore, one option is to increase the energy produced by solar panels through solar tracking. The paper focuses on developing an automatic sun tracking
