Glass easily transmits short wave radiation which means that it possess little Interference to incoming solar energy but it is a very poor transmitter of long wage radiation. Once the suns energy has passed through the glass windows and has been outside. Glass therefore acts as a heat trap a phenomenon which has been recognized for some time in the construction of greenhouses which can get quit warm on sunny days, even in the middle of winter this has come to be known in fact as the greenhouse effect. Solar collectors for home heating usually called flat plate collectors almost always have one or more glass covers although various plastic and transparent materials are often used instead of glass. With fuel hikes making news, solar energy is the most sought-after energy Source. Solar chargers are simple, portable and ready to use devices which can be used by anyone especially in remote areas. Going solar can solve more than one problem, right from cutting down on carbon emissions and dependence on fuels, to solving the energy crisis. This paper aims to make a simple solar charger which can be used on the go. Solar panels don’t supply regulated voltage while batteries need so for charging. Hence, an external adjustable voltage regulator is used to have the desired constant voltage. A Zener diode switches on to ensure charging is cut off at the saturation point.
