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.

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.)

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.

The sun can be used in many ways.
1.To run a car – solar cars2.To cook – solar oven3.To heat a house – radiation4.To feed a plant – photosynthesis5.To produce electricity – solar panels
