How It Works 4o6m1e

Solar energy is the energy we acquire from the sun. Millions of years before humans realized the sun's potential as a electrons are suddenly knocked free and are channeled to flow in the same direction by electric fields within the PV cell. On both the top and bottom of the silicon, metal s are placed and, through these s, the solar energy is extracted and stored.

Practical Uses 1j252q

Solar energy is used for a variety of different things but the ones that you are most familiar with are solar-powered calculators, solar-heated swimming pools and maybe even the hot water in your house is heated by solar s. Because solar energy is clean and renewable, it would be ideal to gas to solar on a grander scale, so research is ongoing to make solar energy a more cost-effective alternative for people around the world.

  • Solar energy is measured in kilowatt-hours. One kilowatt hour (kWh) is the amount of energy needed to burn a 100 watt light bulb for 10 hours.
  • Enough sunlight falls to Earth every hour to meet the world's energy demands for an entire year - the trick is learning how to extract that energy in a cost-effective way.
  • Approximately 10,000 homes in the United States are run entirely on solar power.
  • Solar energy can even be used to cook food!
