What can solar power energy be used for?

Answer 1

Solar energy is used for

1. Heating water, usually on rooftops of houses,
2. Heating greenhouses in cold climates for food crops,
3. Heating houses and buildings through walls and windows,
4. Generating electricity, usually through photovoltaic (PV) cells, again on rooftops. It can also be harnessed through solar towers, where hundreds of mirrors focus the rays onto a central point where a medium, for example, salt, is heated up to many hundreds of degrees. Another way is from solar farms of rows and rows of PV panels. All these generate electricity which is fed into the grid and used in households round the world.
