How is solar power used?
|
Solar power is used to generate electricity in a photo-electric, or solar, cell. The electricity can be used in various ways. The large 'wings' of a satellite are panels of solar cells. They provide the electricity to power the craft's instruments. A more down-to-earth use is a solar-powered bike. Solar cells generate enough electricity to work an electric motor, which in turn gives the bike power. | | Solar power can be used to generate enough electricity to drive an electric motor in a bicycle. |
