How can I build a miniature solar panel to power a light bulb?

Question

I just want to try this as an experiment?

also, I would like to do the same with wind?

is there an inexpensive way of conducting these experiments?

Answer 1

According to this article I found, the kinds of solar panels you can build on your own can't even power a flash light bulb, so I guess you will have to buy some.  Plus it sounds like it might even be dangerous to make your own, something about burning a copper plate on you stove.  http://ezinearticles.com/?Build-Solar-Pa...

Answer 2

I know of something that would definitely show you how to build both a solar panel and a wind generator.

Light bulb requires more current that make the size of solar cells panel quite big and very expensive. You may choose a LED to do the same lighting experiment.

Buy 4 solar cells,hook them up in series. It produces 2 volts or less depending on the light source. Choose the solar cell

able to provide 10ma or more. Choose any small size of LED, red LED is the best choice, Make sure it is the 1.6 volt

3 to 6 ma type. Do not use the lazer LED,it requires 3 volts and more current rate. Connect cell output positive to the LED anode. Negative to the cathod. put it under the sun,LED shall light up.
