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. ## Features - ❶【Please Attention】This solar panel is very thin and light, so it is very fragile.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fragile but good *by on Reviewed in the United States 17 November 2025* 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. ### ⭐⭐⭐⭐ Ware angekommen wie bestellt. *by on Reviewed in Germany 14 December 2020* Ich kann aber keine 5 Sterne vergeben, weil die diese 'It's a Gift' sache machen.Geruechten zufolge kann das probleme beim Zoll machen. ### ⭐⭐⭐⭐ Good, but hard to work with *by on Reviewed in the United States 22 February 2026* Great for hobby builds, they are very fragile and soldering on them is not easy, I have found making sure the surface is clean and using an iron around 300c works best. ## Frequently Bought Together - AOSHIKE 100pcs 0.5V 400mA Micro Mini Solar Cell for Solar Panels 52mmx 19mm/2‘’x0.75” Polycrystalline Silicon Photovoltaic Solar Cells Sun Power for DIY Cell Phone Charger - Vikocell 10 Meters Tinned Copper Wire Solar Cell Busbar Tabbing Wire for DIY Solar Panel Soldering (10M * 5MM * 0.2MM) - SUNYIMA 10pcs Mini Monocrystalline Solar Cells Solar System Kit 50mm X 50mm/1.96" X 1.96" 2V 160MA for DIY Charge Solar Panels --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/303274790-100pcs-0-5v-400ma-micro-mini-solar-cell-for-solar](https://www.desertcart.pt/products/303274790-100pcs-0-5v-400ma-micro-mini-solar-cell-for-solar) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-10*
