Capturing heat and light from the Sun

People also ask


  • Where does solar energy come from?

  • Solar energy comes from the sun and can be captured with various technologies, primarily solar panels The 鈥減hotovoltaic effect鈥?is the mechanism by which silicon solar panels harness the sun鈥檚 energy and generate electricity

  • How does solar energy work?

  • The other type of solar energy is called solar thermal, which is made by using the heat from the sun to heat water. Once the sunlight hits the solar panel in photovoltaic solar energy, the photons then excite the silicon molecules, causing them to move around, which generates electricity.

  • How do we get energy from the Sun?

  • Deep in the Sun鈥檚 core, nuclear fusion reactions produce massive amounts of energy that radiates outward from the Sun鈥檚 surface and into space in the form of light and heat. Solar power can be harnessed and converted to usable energy using photovoltaicsor solar thermal collectors.

  • How long does it take for solar panels to form?

  • They take millions of years to form. Solar energy is a renewable resource, and many technologies can harvest it directly for use in homes, businesses, schools, and hospitals. Some solar energy technologies include photovoltaic cells and panels, concentrated solar energy, and solar architecture.
