Solar Cell Large
sku: PRT-07840
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 8V open voltage and 310mA short circuit. We actually took a random unit outside and measured 9.15V open voltage and 280mA short circuit. Under ideal sun conditions (high-noon, clear sky) 310mA is very possible but will vary from cell to cell. We can even get 110mA from inside our office windows!Termination is a 5.5mm x 2.1mm barrel plug, center positive on a 2m cable. Monocrystalline high efficiency cells at 15-15.2%. Mates directly with many of our development boards. Unit has a clear epoxy resin coating with hard-board backing. Robust sealing for out door applications!
Dimensions: 7 x 4.5"

If you would like to tell us more, you can fill out our form if you need some psycho-suggestive questions. Go to the form.
For now I will be using the Koala (PRT-08722) and the ~1Ah LiPo (PRT-00339)
Thanks!
There is no built in diode.
I posted a voltage/current curve on the web page below but it's under artificial light so I don't know exactly what its peak output is in real sunlight. I would estimate somewhere around 1.5-2.0 watts.
