Solar energy

The Sun is the source of almost all our energy. It is a huge ball of hot gases that gives off energy as heat and light. This is called solar energy, which just means energy from the Sun. The amount of energy produced by the Sun every second is a 100 billion times more than the largest coal-fired power station in Europe.

Solar

Sunlight is composed of photons, or particles of solar energy. These photons contain varying amounts of energy that correspond to the different wavelengths of the solar spectrum.. A PV cell is made of semiconductor material. When photons strike a PV cell, they may reflect off the cell, pass through the cell, or be absorbed by the semiconductor material.

solar energy

The steam can be used to make electricity in a power plant. Solar cells use the Sun''s light rather than its heat. When the Sun shines on a solar cell, the cell turns the light energy into electricity. A single solar cell makes only a little electricity. However, groups of solar cells can provide electricity for whole buildings.

What is another name for solar power?

For other uses, see Solar Power. Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power.
