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. The biggest problem for solar is energy storage. Now we regulate the imbalance between generation and load (frequency) mainly with conventional power plants. Once we find a cheap way of storing and converting (rectifying and inverting) massive quantities of electricity, you can regulate frequency and voltage profile with inverters and everything could run on solar energy.

  2. How about this? We place solar panels all over the world and share power with each other (ofcourse after keeping the required energy needed for one's country).. we can also place solar panels in the north and south poles and receive 6months of continuos sunlight… and develop a system to equally distribute the power between the countries… Ofcourse the infrastructure cost would be humongous but if we can develop an efficient system we can power the whole planet….

    Idea 2:
    If we can transmit electricity wirelessly then we can develop a big quad cop or something like that with its own dedicated solar panels which will revolve around the planet with the sun and it will have Solar panels, this way we neednot to worry about cloudy days…. there will be a receiver on the surface.. which will receive the energy and distribute evenly…

    Haha some lol ideas
    Could not help myself from writing it down

  3. I think solar panels would convert more power if they were thicker in depth. Thin Solar-Panels are stuck in people's minds because that is all anyone has ever seen. The Imagination is a powerful thing some people have.

  4. Thank you so much for making this video. I had researched photovoltaic cells so much and only through this video did I finally understand it.

  5. Solar panels convert sunlight into clean green DC electricity. the solar charged controller takes the DC power from the solar panels and regulates it so it can safely charge the batteries to a nominal operating voltage of 48V, the Inverter converts the 48V DC into 230V single phase AC or 380V three phase AC electricity. the AC electricity is sent from the inverter to the electrical service panel (breaker box) to power your house lights and appliances with electricity, the inverter exports any unused excess electricity back into the grid. this energy offset is sold back to the national grid and the bi directional meter istalled in the breaker box spins backwards adding credit to your electricity bill. During peak periods , cloudy days and at night power is readily available from the grid to your home.
