Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials Needed

1) SOLAR PANEL Rated above 5 volts

2)Capacitors-100uF,10uF,100nF

3)IC(Integrated circuit) LM 7805

4)Veroboard

5)Double sider tape

6)9V battery and battery clip

7)Some thin wires

8)A box according to your solar panel size

9)A USB port

Step 2: Making the Circuit

Make the circuit with help of the schematic on the veroboard or pcb.Then connect the solar panel and 9V battery clip to the circuit as mentioned in the schematic.Then connect the USB socket with the help of the usb pinout diagram.Make sure of correct polarity.

Step 3: Fitting Into the Box

Fit all the components in the box with double sider tape

Step 4: Checking

Place it in the sun or under halogen light or set a 9V battery to the clip and connect your mobile with the charger by a data cable to see it working...

    Correct connection is solar panel-diode-insert to the circuit with batteries......

    the diode function is prevent discharge batteries when no sun available with batteries connected......

    you must put a diode or use separate two primaries components.... batteries or sun......

    solar panel is like a battery: when sun present,give you current,when sun is not present absorbed current.........have good light ....

    You need a diode for example 1N 4004, so that you not feed the panel when it is dark.

    ANDREAS01,

    You can add one but it is not nessesery as every mobile has its own anti reverse feed system..........OK.Thanks for suggestion
