#Solar panel with USB A connector is plugged into the #lilygo#tbeam USB micro power in port. The tbeam has a 16850 3400 mAh Li-Ion 3.7 V battery. The panel & tbeam are behind a velux roof window angled at the sky. The sun is shining well today, no clouds. The t-beam shows 4.2 V plugged in symbol in the #meshtastic app. When unplugged from the panel, the t-beam shows 100% charge.

This is test to see how long this lasts - there is no power management circuit.
@adingbatponder supposedly the board manages the charging and use of a battery attached to it, if the power supply is coming in on the USB-C port to the board.
