Another light weight, thin thickness, shape appropriate to change,Can be used to some DIY solar products Material: Polysilicon Silicon Size: 52*19mm/2 x 3/4 inches Power: 0.2w Average Voltage: 0.5v Average Current:About 0.4A Effeciency: About 17percent Arbitrarily change the output power and voltage through different connect way in series or in parallel, meet your needs! 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. Note 1. Because the output power of solar panels depends on solar irradiance and solar panel temperature and other factors Therefore, the measurement of solar panels need under standard conditions (STC). The standard conditions defined as: air quality AM1.5, light intensity 1000W/m2, temperature 25'. 2. Under this condition, the maximum output power by the solar panel is called the peak power. In many cases, the peak power of the module is usually measured by solar simulator. The main factors affecting the output performance of the solar panel are as Follows a. Load impedance b. sunshine intensity c. Temperature d. Shadow 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 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! Application - Solar power stations system - Sloar light,Solar lawn light,Solar garden light,Solar flashlight - Rural electrification, Small home power systems - Power supply for traffic, security, industry - Battery charging system - Other industrial and commercial applications - DIY project for standard framed solar panel - Solar cell phone charger - Solar backpack charger - Other areas Review: Fragile but good - 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: Ware angekommen wie bestellt. - Ich kann aber keine 5 Sterne vergeben, weil die diese 'It's a Gift' sache machen. Geruechten zufolge kann das probleme beim Zoll machen. ## 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 O***H on 17 November 2025* As other reviews note, these are EXTREMELY fragile.
