My Solar Cell Phone Charger

A small solar panel I made that charges my cell phone. Please excuse my ghettoness of cardboard being my base for the cells. It's what I had quickly on hand, and I don't really care that much right now. This is mostly experimental.

The specs are for both panels separately:
~4 volts
~.8 amps

Both panels are wired in series, so the total voltage is around 8.
The panels together charge a battery bank of 4 1.2 volt rechargable batteries, which then charge my cell phone.

I have not tested how long it takes to charge all 4 batteries from completely dead to fully charged, but I would say that it would take roughly around 1-2 hours.

I would also like to thank those who post useful videos on how to do build your own solar panels. They are very inspiring and very helpful. One in particular, RobertSmith3 is building a ~63 watt solar panel, in which I have found his videos to be quite informative and useful. Check his out:

what the fetch is that??

[DHarrisChillin]

@fizzandfrazz hahaha

[jezikime]

what is the purpose of the battery ? how much voltage of your solar panel?

[DHarrisChillin]

@jezikime the purpose of the battery is to charge the phone when there is no sunlight and to regulate voltage, and read the description for your other question.

[elijahlucian]

hey man. what cells did you use to make the panels?

[oldtrucker63]

Is that charging from the Sun light from the photo on the phone,......LOL

Should put a 5v regulator

[jezikime]

i ask if what kind of diode did you used??

[eraldorh]

@jezikime nicad is less effected by overcharging than li-ion battery's so you should be ok, i used a 12volt 7amp battery off ebay for £12 instead which works great and far less chance of overcharging because the capacity is massive.

[jezikime]

since that u used a battery. is there no possibility to over charger the battery? plz. ans. i need help for my project sir .

tnx

[jezikime]

sir, i'm 1st yr high school student. and i'm planing to do my project just like this. but it is operated by coin selector as a switch w/ a timer. if i use 12 v bat of the car, do i have to use potentiometer to convert the voltage? wat should be the good thing that i have to use to convert the voltge.if i use 12 v bat. i have to use the voltage regulator right? it is a mobile phone charger.
