My PV panels convert some light into electricity and produce no heat
for those energy units.
Light is not heat and not necessarily converted to heat. What you feel
from the sun is infrared electromagnetic radiation (arguably a form of
light). You cannot feel the light from the sun.
Nonsense. What you feel from the sun is a broad spectrum from IR to
visible to UV that is converts to heat when absorbed by your tissues.
Visible light is just as sensible as infrared, as heating upon absorption.
Infrared and visible EM are alike in regards to heating. Infrared is not
"radiant heat", although it radiates and converts to heat upon absorption,
but it is no different from visible light in that regard.
"Radiant heat" is a non-scientific concept, although it at least
phenomenologically descriptive. The idea that infrared is somehow
different from visible light in regards to "radiant heat" is a pure
I don't know much about PV panels, but I do know that 100% efficiency
doesn't exist. I do remember hearing that PV devices were at most
about 10% efficient. What is the waste product?
Which explains why I wouldn't say that it is.
Do you have any specific information on what happens to it, then?
Strange, and almost certainly false. Light (apparently "visible light"
here) and Infrared are both EM radiation, and very similar. Infrared
is just slightly lower in frequency (like ultraviolet is on the other
side of the visible spectrum).
Sorry, that is incorrect, while it is possible to make
a radiometer that turns from reflected photons like a
solar sail is supposed to accelerate due to radiation
pressure of reflected photons, the Crook's radiometer
works because the black side gets warm and the
gas press in the thing is low enough the mean free
path is long enough to allow the molecules to bounce
off the black side with more energy than they had
Wrong, if you would have tried it in the freezer,
it will turn towards the black faces and away from
the white ones in the dark for a little while until the
vanes cool off.
But in light, it turns toward the white faces
due to the black side heating the gas molecules.
All you have to do is LOOK, and PAY
ATTENTION, instead of just assuming, and
that gives you first hand knowledge that will
help more than reading books.
