Understanding Solar Panels

What are Solar Panels?

Solar panels, also known as photovoltaic panels, are devices that convert light from the sun into electricity. They are made up of solar cells, which are the building blocks responsible for generating electrical power from sunlight. Solar panels are a key component of solar energy systems and play a vital role in harnessing renewable energy sources.

How Do Solar Panels Work?

Solar panels work by converting sunlight into electricity through a process called the photovoltaic effect. This effect occurs when photons from sunlight interact with the solar cells, exciting the electrons within them and generating an electric current.

Here are the key steps involved in the operation of solar panels:

  • The sunlight hits the solar panel, causing the photons to interact with the cells.
  • This interaction excites the electrons in the cells, creating a flow of electric current.
  • The direct current (DC) is then converted into alternating current (AC) using an inverter, making it suitable for use in homes and businesses.

It’s important to note that solar panels can work effectively even in less sunny conditions, as they are designed to capture and convert both direct and diffused sunlight.
