Solar energy is energy that comes from the sun. It's like a free source of energy! On a sunny day, the sun shines lots of energy down onto the earth. This energy can be used to power our homes and businesses. The energy hits special solar panels, which turn it into electricity. The electricity is then sent to our homes and businesses to use for things like powering the lights and running machines. Solar panels are careful to only take the energy that we actually need, so it's a really clean and efficient way to get electricity.
