How does solar panel works ? basic principle?
Question:
Answer:
Solar electric panels are made up of something called silicon, the same thing that makes up sand. There is more silicon on the planet than almost anything else. Even though you can find silicon almost everywhere, making a solar panel is difficult and expensive. The silicon has to be heated to super high temperatures in a big factory, and then formed into very thin wafers.
When sunlight hits a solar panel, it makes electrons in the silicon move around. (Electrons are teeny tiny specks--they?re way too small for us to see, even under a microscope.) The electrons flow through wires that were built into the solar panel. And presto! We have electricity! We can do whatever we want with this electricity, run a calculator, a CD player, or, if we have big enough solar panels, a satellite! [Solar panels are also called photovoltaic panels. "Photo" means light and "voltaic" means electricity.]
absorb photons and store them
photons react with the surface to directly create electricity, for proof, put some aluminum in the microwave. Its safe, as long as you dont let the aluminum touch the edges, the exploding microwave is a myth.
Nonetheless, make sure its a thrift store microwave. and doe it in a dark room, its really cool!
