Cut near the borders that you've marked so the hole is a bit smaller than the panel.
Cut near the borders that you've marked so the hole is a bit smaller than the panel.
Step 5:
Use hot glue to glue the panel to the hole.
Now glue the other parts to the bottom of the box so they wont move, in the side make a hole as big as the USB cable.
* I recommend gluing the USB output well so sand and dirt wont come in.
**If you had cotton wool in the box i recommend putting it between the panel and the bottom it will also help preventing the parts moving.

Step 7: Recommended Additions
* If you like to you can add a led to the module output so you'll know when its working.
** If your box is big enough you can add a portable charger instead of the USB output so power wont be wasted, that way you'll be able to use it even when the solar panel is not exposed to light.
*** I added a small loop to the side of the box so i will be able to hang the charger when driving the car, going on camping etc.

Which type of booster i can use???
An adjustable boost converter module. It should convert the input voltage from your panel to 5 volts. you can get one on Ebay, dx, ali express, etc.
<p>Where can I get the charger module?</p>
<p>Adafruit.com is a good source and they have a good ibble as well. <a href="https://www.instructables.com/id/Solar-charger-2/?ALLSTEPS" rel="nofollow"> https://learn.adafruit.com/usb-dc-and-solar-lipoly-charger</a></p>
<p>Where do i buy a solar panel?</p>

I bought mine on Ebay but I'm sure you can get one on Amazon Ali express and radioshack stores.
<p>Nice project! I'm wondering what should be the output and input of the portable charger... </p>
Tnx :) the input depends on the solar panel you use, the output should be set to 5 volts.
Did u made a video on YouTube or somthing ..
Not yet but I'm now making videos for the instructables I can.
Its a great project.... Bt I didn't understand d step 2 of it... Can u plz explain it more briefly...
The part I used here is an adjustable boost converter and you can control the voltage it outputs. In step 2 I connected the part to a power source and to a voltmeter, then I changed the voltage to 5v so it fits the USB voltage. If you have any further questions I'll be happy to answer them.
<p>its because i need all the help i can get :)</p>
You can ask anything you want
<p>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 :\ </p>
You're welcome, I think.. search for arduino stores, electronic stores might have it but arduino ones are your best chance I think.
<p>thank you :) i was wondering do u have kik or <strong>something</strong> ?cause i found the part but i well be needing help and i hardly get on here </p>
What Is kik?
Its Like facebook
nope, but I have Facebook
Add me Arely Montesinos
I have an alice in wonderland cover photo
Added
And good luck with the fair.
Can you please tell me the solar panel is of how many volts<br>It is good if you mail me <br>Email id - rahman.zia11@gmail.com<br><br>
It was a 5 volts solar panel.
<p>How much does this cost?</p>
this was a long time ago but it was pretty cheap.. I think the panel costs a few dollars.
<p>whera can i buy <a href="http://www.dx.com/p/dc-3-30v-to-dc-4-35v-adjustable-boost-converter-charger-module-148492" rel="nofollow">DC 3~30V to DC 4~35V Adjustable Boost Converter Charger Module ...</a></p>
On ebay, deal extreme or arduino stores maybe
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.
Tnx great advice
<p>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? </p>
I believe that the 4AA holder cause it has the same voltage
can i use 5.5 volts solar cell
of course you will only need to adjust the output to 5 volts
where can I get a solar panel in the UK anyone
order one from eBay
<p>Thank you for your Instructable</p><p>Nice job.</p><p>Rima</p>

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