Description: Packaged solar cell with barrel plug termination. This is a custom cell produced for SFE - not a small toy surplus item! This unit is rated for 4.5V open voltage and 100mA short circuit. We actually took a random unit outside and measured 4.95V open voltage and 94mA short circuit. Termination is a 5.5mm x 2.1mm barrel plug, center positive on a 2m cable. Mates directly with many of our development boards. Monocrystalline high efficiency cells at 15-15.2%. Unit has a clear epoxy coating with hard-board backing. Robust sealing for out door applications! Dimensions: 3.7 x 2.4"
