Vedic literatures in India even state the use of flying machines which were powered using the sun. Coming 21st century, we have come a long way in developing solar cells which are the devices powering our future, converting sun’s energy into electricity. This work is about using non conventional energy i.e. solar energy for mobile battery charging. Solar chargers are simple, portable and ready to use devices which can be used by anyone especially in remote areas. 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.
