Can you charge a bank of batteries with solar panels in a room with artificial sunlight? February 12, 2010

I was just curious if this is possible: Charge a bank of deep cycle batteries, and use it to run grow lights, and also having solar panels in the room to recharge the batteries that are creating the light.
What about the L.E.D. grow lights?

its possible
but somewhere in the cycle, energy will be lost via heat, so there wouldn’t be any net worth in it
The light energy from the lamps is less than the electric power you put into them.
And the electrical energy produced by the solar cells is far less than the light energy that falls upon them.
And the energy produced by the battery will always be considerably less than that used to charge the battery.
Yours is a perpetual motion scheme, albeit without any motion, and it won’t even work a bit. Think it through and you’ll see why it won’t.
Everyone who has ever learned science and engineering has come up with many schemes like this. I certainly did. The trick is to get beyond this stage and not spend your life pursuing free-energy machines.
