Well, turns out there might actually be something to bright scene
lighting enabling some power
output during a fire at night.
Here is one paper from San Francisco.
http://ufsw.org/pdfs/photovoltaic_systems.pdf
However, firefighters have particular safeguards they should follow day
or night.
The present day lighting may not have enough light energy to be a
problem but that doesn't matter.
Still have to play it safe. I have not seen any facts and figures but
I may just have some firefighter
friends let me take a PV module and illuminate it to test there when I
get back up north.
I think it would be a good experiment at least.

I believe that kind of illumination could certainly put out some voltage
but wouldn't have much, if any, current or power behind it. But could
shock someone.
Any dangerous energy would have to come from a capacitor being charged
up that SHOULD be disconnected
through the rapid shutdown system at that point. And it would have to
have the light shining on it for quite
a while to rack up any watt-hours.

Hi wrenches,
In speaking to local firefighters last year, I had a question that
stumped me. At night, will the light from the flames or the fire
fighters' flood lights energize the array to a dangerous potential?
Any light you can shed (pun intended) would be most welcome.
Shine On!
