small scale!

There is a slight possibility that your luck will improve if you ask about 12V 5w panels, which are made up of many .5V cells. Some companies make cells and only sell them to other manufacturers (or as seconds ending up on eBay). Some companies buy the cells to assemble panels, and some companies make both the cells and the panels.
Going back to your original post, you will never find "a solar cell producing 12v".

Would you happen to know the names of any of these companies?

Well I'm wondering are there any companies that manufacture panels of that size (12v 5w) because I can't find any manufacturers. The company above said they manufacture themselves but use it in their products and don't sell the cells themselves.

Sorry. I didn't see the device you were referring too.

I did see a number of devices that had lithium batteries inside which would charge a cell phone in 3 - 4 hours but even the biggest device using the crystalline cells indicated it would take 12 - 15 hours of sunlight to do the charging.

I am afraid you will not find anything as small as you want that uses sunlight to do the charging you are looking for.

Guys, if you check out the catalogue of this company called value objects (http://www.value-objects.com/downloa...atalog_WWW.pdf) they seem to have found a way to charge a phone using 12V 5W at the dimension of 11.5cm by 10cm

My initial question was wondering if any of you guys knew manufacturing companies that could provide me panels of that size or smaller with the same electronic specifications

OP,The Chinese are well ahead of you in terms of solar chargers or any solar product. And they sell them cheap. Might want to try reselling their product instead of making your own.

Panels for useless junk items?

While I agree that some items in the catalogue represent pure consumerism such as the business card holder, I personally believe in the importance of using solar energy to charge electronic devices, and value the impact that this gap in the market, which I'm potentially operating could have on a global scale.

Would you happen to know any companies that manufacture panels on such a scale?

At 0.5 volts per cell he needs a couple - you have no idea of what you are typing.

Sorry wrong wording, I said a couple not meaning two, I meant just multiple in general. Yeah at .5v per cell it would be much more than a just a couple.

Maybe he meant a couple of "dozen" cells.

I am not sure if you will find one EXACTLY to your specs, usually you will need to use a couple lower wattage and lower volt solar cells that when put together in a panel, will produce 12v and the desired wattage assuming you've assembled them correctly.

Thanks but we were asking for solar cells/panels that can be used for the manufacturing of a solar charger. The question was where can we find a solar cell producing 12v, that is small in size.

Oh ok, I would definitely take a look at ebay. They have tons of solar cells, you can find thin film CIGS solar cells or just regular silicon depending on what you want. I am not sure if you will find one EXACTLY to your specs, usually you will need to use a couple lower wattage and lower volt solar cells that when put together in a panel, will produce 12v and the desired wattage assuming you've assembled them correctly.

Details;

Not sure if you are asking for solar cells to use in mass production of solar chargers, or a solar charger for personal use...but assuming you want a charger I would recommend getting a Global Solar Sunlinq Charger or a powerfilm panel. Global Solar makes the Sunlinq 3 thats super portable with the following specs:

Unfolded: (229 mm x 736 mm)
Folded: (229 mm x 127 mm)
Weight: 198 Grams
Max Output: 6.5 watt (15v at 433mA) (You want slightly above 12v for 12v charging applications)

Sorry if that isn't what you wanted, I'm not exactly sure what you're asking, but if you could be more specific I'd love to help!

Panel Suggestion

Hello everyone, I am currently working on mass producing design driven solar chargers in the middle east and north africa region. I have everything complete except the solar panels. I need 12V 5W solar panels. The only ones sold in my country (Egypt) are around 20cm and I'm looking for something much more portable. I've been searching for global companies to import from but they all work on large scale infrastructure project.

Me and my partner on the project have been working so hard and we're currently at a phase where we aren't working because we're waiting for the panel to be able to test our prototype. We really want to make progress.

Can anyone recommend me any companies that manufacture small scale solar panels for charging electronic devices. I'm certain that there has to be atleast one company out there that caters to this market.

Thank you!

well, the lowest power will be 5watts and this will lead to a smaller panel. On the other hand, we wont be able to use the folding panel which is amorphous due to the drawbacks you have mentioned and few more. I don't know a lot about the folding reflector, if you can tell me more about it would be great.

Also, having a 12v panel with 5watts up till now all i have seen are huge 30cm * 30cm nothing less. Will i be able to get a 12v panel, 5 watts having small dimensions, I mean is it even possible ??
