What is solar energy?

What is solar energy?

The simplest definition is this – solar power is capturing the sun’s energy and converting that energy into electricity.

We all know the sun gives off a lot of light, but it also releases energy called photons. Experts estimate the sun gives off enough of these photons in one hour to power the entire world for a year!

Solar panels are also known as photovoltaic cells.

How is solar energy gathered?The most popular way to collect solar energy is through photovoltaic solar panels. These panels consist of many solar cells, which are made from silicon and essentially work as semiconductors. Solar panels function similarly to batteries – they have a positive layer and a negative layer that create an electric field.

By attaching a conductor to the positive and negative sides of the solar panels, you can create an electrical circuit.When the electrons from the sun’s energy flow through this circuit, it creates electricity!
