This solar panel is made of single-crystal material that performs high solar energy transformation efficiency at 17%. It has a fine resin surface and sturdy back suitable for outdoor environments. A 2mm JST connecter is attached to the penal, which makes it perfect to team up with most of our can-use-solar-power-supply boards, like Seeeduino microcontroller series, Lipo Rider charging boards series and XBee carrier WSN products series.
The typical open circuit voltage is around 5V, depending on light intensity. In those bright summer days with clear sky and big sun, the peak OC voltage can rush up to 10V. To prevent any damage to boards that accept a narrow range of input voltage, like Lipo Rider, it’s recommended to check whether the OC voltage is safe before any connection.

Wiki of 3W Solar Panel 138X160
Great Value in a 3W Panel I have been buying these from Adafruit and paying much more. This panel seems to work well and is keeping my project running. I have installed it permanently in our local park and will see how it holds up over time. Mounting can be an issue as there is only a thin back-board and no mounting screws so I glued a piece of angle aluminum with a 1/4 20 camera mount adapter. Then I used a trail camera tree mount to attach to the tree. So far, so good.

Hi there~ This panel can work with the board witch support solar panel, or you can use it with our Solar Charger Shield v2.2. Then you can use the panel with any board you want. ================================================================ https://www.seeedstudio.com/Solar-Charger-Shield-v2.2-p-2391.htmlAnswer by: admin on 2018-12-18 02:29:36
How much lux are needed for the specified 540mA and how will it perform under typical indoor conditions?Question by: admin on 2018-12-18 02:24:22
38000 lux is required to generate 540ma. We suggest the outdoor usage, it can't be used for indoor. thanks.Answer by: admin on 2018-12-18 02:24:22
