## Description

Product description: 100pcs 0.5V 52 * 19mm/2 x 3/4 inches Polycrystalline Silicon Solar Panel DIY Charger Battery Solar Cell Description: Size: 52*19mm/2 x 3/4 inches (Customize the size for you as your requirement.) Power: 0.2w Average Voltage: 0.5v Average Current:About 0.4A Effeciency: About 17percent Connection way: The blue side connect "-"(negative) , white side connect "+"(positive). In order to ensure enough power, Suggest use solder strip or copper strips to connect. Attention: There may be some solar panels have a small spots on the side, please don't worry, it's normal phenomenon and will not affect the function of the solar panels.Please choose the cells carefully,it's micro and super thin,so it breaks easily in transit,but please contact us once you get it have any problem. The color is blue, becouse of Production process reasons, Unavoidable color depth is different, some panels is deep, some panels is pale. But it has the same function.(you can see it in the following image) On the use and testing: the product can only be used in the sun, the nominal power is noon sun peak, morning and evening sun and not strong sunlight is not up to the nominal, which the buyer attention! And in the light Inside the room, the solar panel is almost impossible to detect what value! This is the ordinary light and the sun light caused by very different! So be sure to test under the great sun!If you have other size require ,we can customized according your size require,of course,the quantity should not be too small,Please do not hesitate to contact us for further information. Package include: 100pcs.

Review: As other reviews note, these are EXTREMELY fragile. That said, they do what they say on the tin (for the most part). Most of the ones I've tested end up reading in the 0.6v range under intense light, and have a consistent gradient of output as light is applied. They're trivially easy to get dirty - 90% or better isopropyl alcohol seems to do a good job for cleaning, and doesn't degrade the cells.
Review: Ich kann aber keine 5 Sterne vergeben, weil die diese 'It's a Gift' sache machen. Geruechten zufolge kann das probleme beim Zoll machen.

## Questions & Answers

**Q: What is the current rating for these cells?**
A: Ok I bought these a while ago and figured out the Amperage mistake/misspelling, The Seller answered "Average Current is About 0.4A,Power: 0.2w 
Average Voltage: 0.5v".............It's 0.04A, not 0.4A, .............im getting about 30-50 mAh under a bright bulb, Also when building panels, in Series voltage is "all cells combined" But Amperage does not go up the same way, so you can build series/parallel circuits(Sets) In Parallel voltage remains the same when cells combined but amperage goes up each cell(combined )

**Q: How do you connect the solar cells? Mine do not have blue markings and the only way I know which edge is positive and negative is by testing each cell**
A: Hi friend,you need to use the welding strip to connect it ,and the Gray side is the postive , the Blue side is the negative ,so hope it can help you,thanks

**Q: Hello, what is the size (Dimension) of these solar cells, please? I need one that is 3" x 6"**
A: Hi friend,this solar cells size is  3/4”x2” inch,if you want large size,pls check this link:https://www.amazon.com/dp/B07DC4VKBG, hope it can help you,thanks

**Q: What can be applied over or under these cells to make them more rigid and less fragile?**
A: Hi friend,you can use it made the solarpanel diy ,and use the welding strip to connect them,thanks for your questions

### ⭐⭐⭐⭐⭐ Review
*by E***E on 24 May 2017*

Cells are very small - 2 x 3/4 inches. The entire stack of 100 is an inch thick. Each cell is thinner than a postcard, line them up and you can feel the difference with your finger. The entire thing is about three stacked dominoes, the only things I could think of this small. They come extremely well packed. Lots of bubble wrap around a plastic-wrapped bundle of the cells. Still, delicacy is required in handling them. This is an incredibly thin glass substrate. I'm guessing a few will be broken in testing how to mount them to an adequate base material. They seem very powerful for their size. Under a very bright light the yield was 0.65 volts and 140 mA. The current surprised me. It will be interesting to see the results under sunlight. Getting 100 seems about right. There will be breakage at various steps because they are so delicate and I don't need all 100 for my projects. I like being able to make custom arrays of different voltage and current outputs and the price was awesome. Very pleased with the purchase.
