FAQS about Using solar energy to generate electricity and heat

What is solar energy & how does it work?

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.

How do solar panels turn sunlight into electricity?

There are several ways to turn sunlight into usable energy, but almost all solar energy today comes from “solar photovoltaics (PV).” Solar PV relies on a natural property of “semiconductor” materials like silicon, which can absorb the energy from sunlight and turn it into electric current.

How is solar energy generated?

Solar energy - Electricity Generation: Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.

What is solar energy?

solar energy, 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.

How does a solar power grid work?

An electric grid with lots of solar power must pair it with other technologies for reliability: energy sources like hydropower that can be powered up and down at will, energy storage (like batteries) to save up solar energy when it’s plentiful, and/or long-distance transmission to move electricity from the sunniest spots to where it’s needed.

How do solar panels work?

You're likely most familiar with PV, which is utilized in solar panels. When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.
