CONSTRUCTION OF 12VOLTS BATTERY CHARGER

Abstract
We have used locally sourced electronic components to construct a 12V electric battery charger. So also, four solar panels of 40W each were installed in series to charge 12V batteries. Attempts were made to compare the charging rates of the two sources of power. However. difficulties were experienced because public power supply was electrical inadequate to power the charger anel tht' solar panels could not charge optimally either because due to the season. Upon construction. the charger Mts found to be working perfectly while the solar panel arrangement gives maximum output with respect to its rating with maximum solar irradiation.
