Monocrystalline Silicon Solar Panel 2V 160mA 50*50mm

& 800 Lumen Philips 10.5W bulb 2700K.

The next step is to get the blue light that flashes when it boots with a standard 3.7V battery & recharge the battery at the same rate it discharges. A larger solar panel will easily work, but I had to unplug it because the Nano immediately started smoking, not realizing I was using the wrong 4.4V out with an Adafruit Solar Lipo Charger. Really important tip: Make sure you have the right regulated output or it will fry the MCU

I attended a webinar by E-peas, Epishine & Cap-XX, and found this slide helpful

Testing new multimeter

2/18: 1st successful test of any indoor panel: Panasonic AM-1816CA with Waveshare Solar Power Manager (even though the latter is for 6V-24V) the AM1816CA is 4.9V.

Cowboy Studio 85W (450W equivalent) CFL was used.

The boot light (top right corner) also flickers on with enough light, but hasn't been able to charge a 3.7V battery yet.
