Wow, even with cloudcover and it being winter (less hours of sun and more atmosphere absorbing the energy of the light we do get), my #solar node went from completely dead to 6%.

I'm not sure if it died overnight, but it was still on at midnight, which is far better than I expected.

I'm not sure how replicable it'll be since I hand made the solar panel and battery pack, but I'll share what I've learned.
