Abstract
As non renewable energy sources are getting exhausted from earth, renewable energy sources need to be incorporated for daily needs. Mobile phones have become a vital part in life and its importance has increased so much that it needs to be kept charged. This paper proposes a system which is powered by solar energy to charge the mobile phones. The proposed system is designed to trap the solar energy and store it in a rechargeable battery. A mechanism to limit the over current flow in the circuit and to prevent the draining of battery and low voltage operation is incorporated in the system. Many low-voltage devices including mobile phones can be charged using this system and the charge in the battery is displayed with the help of LCD and a micro-controller
