Hi Ted:
it seems that the low voltage used in the application is being
mistaken for low energy. Your garden variety alkaline manganese cell
has such a low internal resistance that it behaves as a little bomb when
shorted. Same with lithium battery technology. If the solar cell can
class from a safety point of view as a high voltage section developed
directly off the mains.

, MIL-STD-810) solar intensity test level is 1120W/m^^2.

I thought the Suns Solar Intensity was 1kW

For the power limit part of the problem, a good rule of thumb to use for
solar
intensity is 1 kW per square

To all,
First, a little background.
I have been asked a question that I did not know the answer to, which
relates to a potential new
product. As I understand it, this device will be relatively small,
consume very little power

Some help, I hope, to your questions.
Would this small LCD display device even be required to be evaluated to
IEC 60950 3rd Edition or to IEC 60950-1?
This depends on what you are trying to achieve, good company practices,
or a countries
