How Do Solar Panels Work

Solar Panels are made of semi-conducting material. When sunlight falls on it, the photons knock electrons from the surface atoms. This results in positive charge on the surface, which causes flow of electrons. Solar panel is an array of smaller photo-voltaic cells linked together.

Solar panels provide energy in such places where it is impossible to provide current electricity from power stations; satellite, GPS in deserts and mid-sea, or portable devices like calculators.

This energy is clean, which means that no pollution is generated by producing them. Also called ‘green’ energy.
