How Solar Energy Works For Kids?

The sun shines on the solar panels and the panels absorb the energy creating direct current (DC) electricity. The electricity is fed into what is called a solar inverter. This converts the current into alternating current (AC) electricity. The AC current is then used to power the appliances in your home.

How is solar energy working?

Solar power is harnessed using Solar Photovoltaic (PV) technology that converts sunlight (Solar radiation) into electricity by using semiconductors. When the sun hits the semiconductor within the PV cell electrons are freed and bus bars collect the running electrons which results in electric current.

How does solar energy work simple explanation?

When the sun shines onto a solar panel energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell causing electricity to flow.

How do you explain solar energy to a child?
