how is solar energy produced from the sun ?

how it works ? how do the solar panels create solar energy from the sun ?

    The sun produces energy from Thermonuclear Fusion…The radiation from its surface comes to the Earth.

    Solar panels are silicon (or other materials) that are processed to convert solar Radiation into electricity directly.

    There are other methods that convert solar radiation into electricity.

    There are three ways:
    1–Bio fuel, which is organic matter produced through chlorophyll in plants. That makes fresh green matter to ferment to alcohol, or to make peat, oil and coal over the ages.
    2–Solar heater units that gather sunlight with mirrors and heat tubes to boil a fluid and make steam for turbines.
    3–Solar photovoltaic panels that produce a flow of electrons. A special combination of chemicals have an unbalanced excess of electrons that are loosely bound.
    The action of photons on these chemicals raise the electrons to a higher energy level, where they spring free of the atoms, and they flow through a circuit.
    One can argue that even wind turbines benefit from solar energy, but that seems stretching the definition to me.

    A photo-voltaic cell converts sunlight directly into electricity. The light from sunlight excites the electrons in the atoms directly. It is so simple very few people understand it as they assume it must be more complex than it seems.

    Check out this web site however, it should explain it a lot better than I ever could.
