Video explanation of solar photovoltaic use

What is solar photovoltaic (PV) & how does it work?

Solar photovoltaic (PV) systems can generate clean, cost-effective power anywhere the sun shines. This video shows how a PV panel converts the energy of the sun into renewable electricity to power homes and businesses. Failed to fetch

Can solar power convert the sun's light and heat into electricity?

In this video from NOVA's Energy Lab, learn about the benefits and limitations of converting the Sun's light and heat into electricity. Animations show how two solar power technologies—photovoltaic cells and concentrated solar power systems—convert the Sun's energy into electrical energy.

What is a photovoltaic system?

The literal translation of the word photovoltaic is light-electricity—and this is exactly what photovoltaic materials and devices do—they convert light energy into electrical energy. PV systems generate power without pollution—and recent advancements have greatly improved their efficiency and electrical output.

How do solar panels work?

When sunlight hits layers of silicon inside solar cells, an electric charge builds up, creating a flow of electricity. Solar panels are mainly located on the roofs of homes and buildings and can generate electricity and heat water free of charge. In the Northern Hemisphere (including Scotland) solar panels work best when they face south.

Do solar panels generate electricity at night?

Solar panels generate no electricity at night time. Solar panels can't store energy, so you have to use the electricity they generate when the sun is shining. You need batteries to store the energy generated. These are expensive. – Solar cells convert the light from the sun into electricity.

Are solar power technologies environmentally friendly?

Animations show how two solar power technologies—photovoltaic cells and concentrated solar power systems—convert the Sun's energy into electrical energy. Solar power technologies are environmentally friendly, but there are technological challenges that limit their widespread use.
