Electrical Engineering: Possible Electric Circuit For Solar Mobile Phone Charger

The solar energy supply is limitless. Its a good source of energy that should be harnessed for our mobile devices.

Here is an idea to harvest Solar energy for charging i found in my research for simple solar alternative power devices online. This charger is said to be able to charge almost all types of batteries such as Mobile phone batteries. It uses a solar panel to convert light in to electrical energy.This circuit explains itself.

A 12 volt and 5 watt solar panel is used as source of current.The cells in the panel are made up of semiconductor material which convert sun light energy in to electrical energy.

The solar panel can generate up to 16.5 volts with 400mA current.This current is able to charge mobile phone battery.

Diode D1 allow current to pass in to three regulator ICs to get regulated output.This output voltage is able to charge Lead Acid battery.The battery can be connected to point C and ground.IC2 gives regulated 6 volt to charge NiCd battery. IC3 provides regulated voltage to charge all types of mobile phone batteries which is rated at 3.6 volt. Red led indicates its charging the battery.
