Solar energy articles for students

What is solar energy?

Solar energy is any type of energy generated by the sun. Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.

Why do we need solar cells?

Proper placement of solar cells maximizes energy productivity. Solar energy is an important and popular form of renewable energy that could help our communities move away from nonrenewable resources like coal and other fossil fuels. Idea for the Classroom Introduce students to the science behind solar cells and how they work.

Idea for the Classroom Introduce students to the science behind solar cells and how they work. Then, using the infographic, ask students to answer the questions below:

Can a solar cell make electricity?

The steam can be used to make electricity in a power plant. Solar cells use the Sun’s light rather than its heat. When the Sun shines on a solar cell, the cell turns the light energy into electricity. A single solar cell makes only a little electricity. However, groups of solar cells can provide electricity for whole buildings.

Are solar panels environmentally friendly?

Solar panels create no harmful gases, so it is very environmentally friendly. If the sun is shining on a solar panel on your house, you are able to use the energy for free, reducing electricity bills.

Can solar power be generated on a cloudy day?

While solar power can be generated on a cloudy day, some level of daylight is still required in order to capture the sun’s energy, and the amount of energy that can be produced varies greatly depending on the amount and quality of direct sunlight that the panels receive as well as the size, number, and locations of the panels.
