Solar power works when solar cells, also known as photovoltaic cells,
are made into solar panels set up to receive sunlight. Solar cells
generate electricity from the sunlight that hits them. Solar power
plants can be set up, but this technology is also useful on a small
scale, for solar power home heating and home electricity generation.
Sunlight can also power solar ovens, which cook using sunlight-powered heat,
and solar water heaters.
