Mini 6V 1W Solar Power Panel Solar System DIY For Cell Phone Chargers Portable

Excellent little solar panel
I bought a few of these to power an ESP8266-based weather station. I only ended up needing one. In southern Idaho, I'm getting over 100mA net charge into an 18650 cell for most of the day, and 140mA or more at noon, which is plenty for my application. Note that this is around 0.8W peak, which is less than advertised, but way more than I expected. The panels are slightly convex (1-2mm) over their length, but this doesn't affect my application.
