Abstract: The voltage-time characteristics of a 140 W, 33 V solar panel is presented in this research. The readings and plots obtained shows that the terminal voltage of solar panel depends on time of the day. Between 7:30 am to 6:00 pm, the terminal voltage of solar panel is at maximum. From 7:00 pm to 6:00 am, the terminal voltage of the solar panel is zero. A storage battery is therefore, necessary to store electrical energy to be used at night. The voltage generated by the solar panel depend on the geographical location of the site, time of the year, time of the day and local weather condition. The geographical location and climatic conditions of Ekpoma in Nigeria favours the use of solar power system. The successful implementation of solar power programs will go along way in reducing the power supply problem, poverty alleviations and climatic changes in Nigeria and the world at large.
