Solar Panels

Solar panels are panels that get light from the sun to generate light and power up batteries and other electronics. It doesn't use electricity. Solar panels are useful in many ways, but they're virtually useless between sunset and sunrise. Anyone uses this or know someone who does or know who works on solar panels?

I heard about solar panels, but I don't use them. I know that my old soccer coach works on solar panels, and even suggested that my father could use some solar panels. :p
