## 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
