This study analysed battery charging performance using 12 volts PV cells and a designed system. Specifically, this: 1) analysed battery charging performance: a) at varying amount of cloud cover in the atmosphere; b) with different capacity of solar battery, and 2) This analysed voltage behaviour during battery relaxation. It designed a system with four 12V, 100W and three 12V, 50W solar panels in parallel to produce 12V, 550W power output. The system was used to analyse voltage behaviour in charging two 12V, 100AH batteries, one is a dead while other is functional. Voltage reading was done using the open circuit voltage (OCV). The behaviour of voltage in charging of two batteries were interpreted through the derived mathematical model and by differentiation. It was found that the designed system of collecting energy is capable of charging 12V, 100AH battery within four hours when the atmosphere is cloudy and is shorten to two hours in clear atmosphere even if the charging time is started at early 6:00AM. However, the event is not applicable for the dead battery. During battery relaxation the battery is in equilibrium situation within four hours noting that the voltage reading does not change while it is decreasing in dead battery.
