  1. Solar Energy  Electricity

  2. Earth’s Solar Balance

  3. 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. 

  4. The silicon has to be heated to super high temperatures in a big factory, and then formed into very thin wafers. 

  5. 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.)

  6. As the electrons get moved and bumped around they get converted from a negative to a positive flow of electric current. This current travels through wires and into your home.

  8. The sun can be used in many ways. • To run a car – solar cars • To cook – solar oven • To heat a house – radiation • To feed a plant – photosynthesis • To produce electricity – solar panels
