The last two days have been mostly overcast, and my $8 solar panel is only able to catch the sun for a fraction of the day, but everything on my #Meshtastic trash node seems to be holding up fine.
Of course, it's on CLIENT_MUTE, so it's not exactly transmitting very often, but this bodes extremely well for when it gets promoted to full mesh participant when we go camping.
I'm going to install a little 5V DC-DC converter and a USB socket on it as well, so we can slow charge devices off the battery when its got juice to spare.
