I use one such panel with a 12V battery and 5V USB output to
charge the nanonote, cellphone and a few other gadgets:
during the winter there are no issues, but during the summer
the gadgets tend to become a bit warmer than I'm confortable with.
I believe it is better to charge the panel battery[1] under the sun
and then charge the nanonote from the battery indoors (or during
the evening, or otherwise in the shade.
[1] a common car battery, in my case
