How solar energy is produced and how we recover it?
Description of solar: Solar energy is radiant energy from the sun that travels to Earth in electromagnetic waves or rays. How solar energy is produced and how we recover it: Solar energy is produced in the sun’s core when atoms of hydrogen combine under pressure to produce helium, in a process called fusion.
How the solar energy is produced?
Solar panels use the photons produced by sunlight to generate direct current (DC) electricity. When the photons hit the panel they are absorbed by the panel’s semiconducting silicon material. … The DC electricity then flows to the systems inverter where it’s converted to alternating current (AC) electricity.
How do humans obtain solar energy?
Solar collectors capture the sunlight and turn it into heat. People can heat their houses and their water using the sun’s energy. Solar cells can turn solar energy into electricity. Some toys and calculators use solar cells instead of batteries.

How is solar energy used today?
Solar energy is used today in a number of ways: As heat for making hot water, heating buildings and cooking. To generate electricity with solar cells or heat engines. To take the salt away from sea water.
Is solar energy renewable?
WHAT IS SOLAR ENERGY? Solar energy is that produced by the Sun’s light – photovoltaic energy – and its warmth – solar thermal – for the generation of electricity or the production of heat. Inexhaustible and renewable, since it comes from the Sun, solar energy is harnessed using panels and mirrors.
