D130mm 1W 5V Solar Panel-backI am excited. Our version 6.0 OpenCharger panels are hot off the press in Schenzen. I’ve been working on these babies for the last two years. They are compatible with bamboo, old CDs, and don’t require soldering. Plus they allow indefinite power scalability by joining one panel to another into mandalic matrixes. We’ll be using these babies to moblize small groups in Nepal to make their own solar charging lights from local bamboo and ewaste.
