A Solar Battery Charger circuit is designed, built and tested. It acts as a control circuit to monitor and regulate the process of charging several batteries ranging from 4 volts to 12 volts, using a photovoltaic (PV) solar panel as the input source for the battery charging process. The circuit is economical and can be easily constructed from discrete electronic components. The circuit operation is based on matching the solar panel terminal load voltage to the input terminal of the charging circuit and the appropriate number of battery cell units to be charged to the output circuit through the use of a current limited voltage regulator, allowing fast charging while limiting heat build-up and gassing and a rotary switch for easy selection of the appropriate voltage depending on the solar light intensity. Experimental results indicate that there is an increase of the overall charging current when fully charging an empty: mobile phone battery and a 6v rechargeable lamp for 4 hours using direct charging between 10.00am to 4.00pm. The success of this device will bridge the gap of power failure that often occur within the hours of the day between 10.00am to 4.00pm, especially in rural communities.
