These panels come to us from Voltaic Systems, makers of fine solar-powered bags and packs. These are waterproof, scratch-resistant, and UV-resistant, and they use 10 high-efficiency monocrystalline SunPower cells with 22+% efficiency (praise the sun!). Each cell has a nominal voltage of 0.5V so we call this a "5V" panel. Note the datasheet has it down as a 6V panel, because at max-power-point it will give you 5.9V

They output approximately 6V at 50 mA peak via two solder-able pads on the back. The panel is constructed with ETFE (Ethylene Tetrafluoroethylene), making it extremely durable and resistant to environmental elements, a superior upgrade to PET or laminate solar panel construction. They can easily stand up to typical outdoor use, including being dropped and leaned on. 

Unlike the larger panels, these don't come with a connector. Instead, there are two pads on the back. We recommend soldering two wires and attaching a 2.1mm terminal block to connect. (Or you can cut off the alligator clips from a 2.1mm-to-clip adapter)
