Picture of Solar charger
In this step-by-step guide i'm about to teach you how to design and build a simple solar charger.

What you'll need:

1) Solar panel.
2) Adjustable Boost Converter Charger Module.
3) Electrical Wires.
4) USB female cable.
5) A box.
6) Recommended  - portable USB charger, a cord, led. 
7) Soldering Tin.
8) Duct tape.


1) Plier.
2) Soldering iron.
3) Hot glue gun.
4) A knife.
5) Tweezers.
6) Voltmeter.

Step 1: Attaching wires to the panel

Solder electrical wires to the solar panel (Red to +, black to -).
Cover it with the duct tape.

How much does this cost?

this was a long time ago but it was pretty cheap.. I think the panel costs a few dollars.

crashzoom (author)  DeezzNutts3 months ago
Not yet but I'm now making videos for the instructables I can.

its because i need all the help i can get :)

crashzoom (author)  DeezzNutts3 months ago
You can ask anything you want

Thank u so much i was wondering is there any stores that sale charger module cause i am doing this solar power charger for a science fair project and i have everything that i need besides that and i need it by Friday :\

crashzoom (author)  DeezzNutts3 months ago
You're welcome, I think.. search for arduino stores, electronic stores might have it but arduino ones are your best chance I think.

thank you :) i was wondering do u have kik or something ?cause i found the part but i well be needing help and i hardly get on here

On ebay, deal extreme or arduino stores maybe
ragyarko made it!5 months ago
it.really good
I would recommend using a dc to dc step up module eBay item number 321333677611 this will allow smartphone charging. because the solar panel is only a few hundred milliamps I would also recommend charging the phone in the off state as your phone may not charge at all if it's on. my phone pulls .94 amps while charging, that's 940 milliamps.

so i have a 4 AA battery holder, and a 7.2V NiMh RC heli battery. which would be more feffective with the use of a 6V solar cell?

crashzoom (author)  Mr_Rep7 months ago
I believe that the 4AA holder cause it has the same voltage

can i use 5.5 volts solar cell
crashzoom (author)  97737769017 months ago
of course you will only need to adjust the output to 5 volts

great project...well done...

crashzoom (author)  billbillt1 year ago

Tnx :)

Whats the name of that adjustable boost module? I have a dc-dc buck converter but it does not boost voltage.

That's the one i bought

Great tutorial! Does it matter if you cover the wires with electrical tape or duct tape?
