Is It Possible To Use A Solar Panel To Power A Lightbulb To Power A Solar Panel?

1.Ok, you connect the torch so it is powered but the solarpanel
2.Then you shine sunlight on the panel to get the torch started.
3.Then shine the torch on the Solar Panel to get the panel to power the torch.
4. Then you go inside in a dark room, and the light from the solar panel would power the Torch, and the Torches light would power the Solar Panel.

  1. Unfortunately the efficiency of conversion of energy from one form to another is always less than one. So the out put is always less than the input. After one or two conversion nothing will be left as out put.
    The perpetual machine of the second kind do not exist. Many scientists spent time on this before this conclusion.
    Imagine a light bulb. If we can convert the heat and other emission back to electricity and feed the bulb, the bulb should continue to glow with out taking any power from the line !!!!
    Hope you understood.Thanks for the question

  2. I always thought about this growing up and playing with electronics
    The simple answer is NO.
    The amount of power needed to power a light source to get a solar panel to feed back a greater amount of power to the light source does not exist.
    Theoretically it could work, but unfortunately i don’t think it ever would 🙁 due to the inefficient nature of the solar panels.

  3. it’s impossible.
    1. Because of the solar panel efficiency, the solar panel only could transfer 17% of the lights into electricity.
    2. Because of the power loss, there will be a certain percentage of power loss when it’s transfered in the circuit.

  4. Solar panels are usually only about 3% efficient. They have some that go up to about 20 percent last I heard but they are expensive. It would work but you would need to supply it continuous power since solar cells are inefficient..
