How do solar panels work? – Richard Komp

View full lesson:

The Earth intercepts a lot of solar power: 173,000 terawatts. That’s 10,000 times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? Richard Komp examines how solar panels convert solar energy to electrical energy.

  1. It is one of the best way to produce electricity and environment pollution free,but we are still using a very few of it.

  2. An excellent video detailing how the solar panels work… if only the public utilities would stay out of the way…constantly trying to destruct the economics/payback!

  3. Puedes poner paneles en tu casa, pero la relación costo/beneficio va en tu contra, lo mejor sería montar toda una granja sostenida por recrusos publicos y privados y plantarla en ub area con acceso constante al sol, en Chile lo lograron? Cómo no lo va a lograr Estados Unidos o México?

  4. even we can cover high ways with this type of cell and can be charge the vehicals on highways

  5. My solar inverter was affected by lightning and I wanted to learn more. Africa needs to step up to this challenge. We have all the sun in the world, yet we lack consistent electricity. Solar setups are becoming increasingly expensive and the Government isn’t helping matters. Nevertheless, I’m very optimistic that the future is brighter than we have imagined.

  6. the north pole haves like 100 days of sunlithg
    so ummm
    if we fill it with dirt and put solar panels there it amm mithg work ?

  7. sure there's the idea that coal and oil makes more money, but the idea that eventually, renewable energy will the key to sustaining the entire future is something that will and must happen. Elon Musk, sees this

  8. 1 question: Solar panels work by taking in energy from the sun that would mostly have been reflected back to space. Doesn’t this cause global warming?

  9. I live in a place that is entirely powered by hydro
    While it isn’t solar, I will say it is very cool to be powered by renewable instead of fossil fuels

  10. At 4:05, the video says 3 million square miles equals 4.8 million sq kilometers. We know that's wrong since it's a squared term and they didn't square the mile to km ratio. It's 7.8 million sq kilometers.

  11. The fundamental problem with solar generation of electricity is that it takes more power to produce a photovoltaic cell than that cell will produce throughout its usable life.

  12. I work in the solar industry and there are amazing things out there in the works. As technology gets better we will be able to see solar help in many different ways and renewable energy really is changing the way the world works.

  13. solar energy is very nice, especially if the electric grid isn't an option, but nuclear is far better for the grid with much less material costs and smaller footprints.

  14. What if you put an LED lightbulb inside of a box where all sides are covered with solar panels, then link the energy output to the lightbulb, then start the cycle by temporarily taking off one side of the box? Would you have infinite energy?

  15. Since 2015 in Yemen we are relying on solar systems power up everything yes they are not enough but at least they are feeling the basic needs of electricity
