it is an idea..
but there are two problem...
first sloar panels are not effecient enough to convert all the energy they recieve
the second, and bigger issue is the first law of thermal dynamics.
which states that the increase in the energy of a closed system is equal to the amount of energy added to the system by heating, minus the amount lost in the form of work done by the system on its surroundings.
and where this comes in is the "lost by work"
your lights generate light from electricity. the work to do that takes energy, and then the solar panels would have to "work" to convert light to to energy.
so here is an example of what i mean (these numbers are pretend and not exact but will get you to the point)
150 watts goes into the lights
25 watts lost in the generation of that light
the solar panel will not receive ALL the light.
so lets say it get 50% of the light energy
62.5 watts is received by the solar panel
25 watts lost in the conversion of that light to energy
leaves you will 32.5 W of energy to now feed your lights and everything else
needless to say thats not enough
we can use solar panels with the sun because it generates more energy, and with the loss we still have enough left over to be productive
(physics is another one of my "hobbies.. )
