Summary

Solar panels absorb light from the sun and turn it into electricity. They can power everything from a calculator to a whole country! How does this sunny science sorcery work? We asked solar power expert Karl Wagner to help us find the answer.

From the brains behind brains on, this is the moment of um.

Moment of um.

0:05.0

Moment of um comes to you from 8 p.m. studios. I'm an electron.

0:12.0

Um. I'm an electron. I'm a super tiny particle, so small you can't see me with just your eyes, but that doesn't mean I'm not super

important.

0:22.0

Us tiny electron particles help make up the atoms that make up everything.

0:26.0

So we're sort of like the LEGO pieces that help build the universe.

0:29.0

Super important.

0:30.0

Right now, I live with a few billion of my fellow electrons in the atoms that make up a piece of glass.

0:35.0

It's a great place, but there's not much for us electrons to do so it can get a little boring.

0:40.0

But lately, there's been a lot of gossip about our piece of glass being added to a solar panel. Can you imagine?

0:47.0

I hear that electrons in solar panels get to do all kinds of amazing work. They become electricity. At least that's what I heard. I don't actually know how

0:58.1

solar panels work. My friend Beckett and Jackson were curious too.

1:03.0

Hi, I'm Beckett and Jackson were curious too. Hi, I'm Beckett and I'm Jackson and we are from El Swede in California

1:11.0

and we were wondering how do solar panels work.

1:15.0

The main part of a solar panel is the silicon wafer.

1:21.0

My name is Carl Wagner and I'm the founder of the Museum of Solar Energy.

1:25.0

Everything else around the solar panel is basically just ways to protect that thin piece of glass.

1:30.0

The next layer is what they call the encapsulate.

1:33.0

If you ever held like a silicone baking sheet,

1:36.0

it's kind of that same rubbery feel that covers that.

1:40.0

And on the other sides of that are a piece of glass and another piece of plastic just to kind of seal out the water and make sure light can get through to it.
