Solar energy for dummies

What are the basics of solar energy?

Solar energy (or solar power) is the energy we generate from sunlight. Through a process known as the photovoltaic effect, we can convert energy from the sun’s rays into electricity that can power our TVs, refrigerators, lights and other appliances. (The photovoltaic effect is what makes solar possible.

How does solar power work simple explanation?

A solar panel “works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity,” according to Live Science. That’s a technical way of saying that the panel’s photovoltaic cells convert the energy in sunlight to electricity (specifically, direct current (DC)).

How do you explain solar energy?

Solar power is energy from the sun that is converted into thermal or electrical energy. Solar energy is the cleanest and most abundant renewable energy source available, and the U.S. has some of the richest solar resources in the world.
