Learn solar energy technology basics: solar radiation, photovoltaics (PV), concentrating solar-thermal power (CSP), grid integration, and soft costs.

Solar projects are making it easier for Americans to choose solar energy to power their homes. Since 2008, hundreds of thousands of solar panels have been installed across the country as more and more Americans choose solar energy for their daily lives.

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. Solar panels use the photovoltaic effect to convert light into an electric current. [2]

Mar 19, 2025 · Solar energy is radiation from the Sun that is 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 energy requirements and could satisfy all future energy needs if suitably harnessed.

3 days ago · There are two main types of solar energy technologies—photovoltaics (PV) and concentrating solar-thermal power (CSP). On this page you’ll find resources to learn what solar energy is; how you, your business, or your community can go solar; and find resources for every step of the way.

Aug 6, 2024 · Solar power is usable energy generated from the sun with solar panels. It is a clean, inexpensive, and renewable power source available everywhere.

Jan 31, 2025 · Solar panels reduce your energy bills, minimize your reliance on fossil fuels, and increase your independence from your utility. They even increase the value of your home by about 4% on average, based on multiple studies. If you pay for solar upfront, you'll spend about $29,000 on average before incentives.

4 days ago · solar power, form of renewable energy generated by the conversion of solar energy (namely sunlight) and artificial light into electricity. In the 21st century, as countries race to cut greenhouse gas emissions to curb the unfolding climate crisis, the transition to renewable energies has become a critical strategy.

Though costly to implement, solar energy offers a clean, renewable source of power. Solar energy is the technology used to harness the sun's energy and make it useable. As of 2011, the...

Aug 29, 2023 · Solar energy is a form of renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use. It is a “carbon-free” energy source that, once built, produces none of the greenhouse gas emissions that are driving climate change.
