What is solar energy?

Solar energy is radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy incident on Earth is vastly in excess of the world’s current and anticipated energy requirements.

What is solar power and how does it work?

Solar power is a renewable energy source that converts sunlight into electricity. In the first quarter of the 21st century, it was the third most widely utilized form of renewable energy, accounting for about 4.5 percent of the world’s total power generation capacity in 2022. The majority of the world’s solar power comes from solar photovoltaics (solar panels).

How do solar panels generate electricity?

Solar panels generate electricity through the photovoltaic effect, which harnesses the sun’s energy. There are two main types of solar energy: photovoltaic and thermal. Solar energy is energy from the sun that we capture with various technologies, including solar panels.

Where can solar power be generated?

Any point where sunlight hits the surface of the earth is a potential location to generate solar power. Solar energy is a clean, inexpensive, renewable power source that we can harness nearly everywhere in the world.

How does solar power benefit the environment?

Solar power benefits the environment. Adopting renewable energy helps to improve air and water quality and helps the country reduce greenhouse gas emissions that exacerbate climate change. DOE partners with national labs to develop innovations that lower the costs of solar energy.

How can you use energy from the Sun?

The two main ways to use energy from the sun are photovoltaics and solar thermal capture. Solar photovoltaic systems are common for smaller-scale electricity projects, like home solar panel installations, while solar thermal capture is typically only used for electricity production on massive scales in utility solar installations.
