    What Is Renewable Energy

    Renewable energy refers to energy that is inexhaustible or never-ending. This means they will never run out, no matter how much of it is used. It is generated from natural energy processes like sunlight, wind, water and geothermal heating and is constantly replenished. On the other hand, non-renewable sources like nuclear power and fossil fuels are finite. They are manmade, using resources that will eventually run out. Our known oil deposits are predicted to run out by 2052, gas by 2060 and coal by 2088. These fossil fuels can take over a million years to form, so once they run out, they cannot be easily replenished.

    How Exactly Is Electricity From Solar Energy Produced

    How Solar Power Works

    Solar panels are usually made from silicon installed in a metal panel frame with a glass casing. When photons, or particles of light, hit the thin layer of silicon on the top of a solar panel, they knock electrons off the silicon atoms.

    This PV charge creates an electric current , which is captured by the wiring in solar panels. This DC electricity is then converted to alternating current by an inverter. AC is the type of electrical current used when you plug appliances into normal wall sockets.

    Degradation Of Battery Backup Systems

    One of the biggest benefits of modern solar systems is their ability to store power produced by the panels. This allows businesses and homes to run on clean, renewable energy even at night. However, most systems rely on a series of batteries to store the excess power collected by the panels during the day.

    And those batteries wont last forever. Once they stop holding a charge or reach a certain age , youll need to hire a contractor to remove and replace them.

    While most solar contractors will make sure the batteries are property disposed of or recycled, accidents can happen. If the batteries end up in the landfill, the chemicals can leach into the soil and pollute the water supplies nearby.

    When Was Solar Power Discovered

    Solar energy was used by humans as early as the 7th century B.C., when humans used sunlight to light fires by reflecting the suns rays onto shiny objects. Later, in 3rd century B.C., the Greeks and Romans harnessed solar power with mirrors to light torches for religious ceremonies.

    In 1839 and at the age of just 19, French physicist Edmond Becquerel discovered the photovoltaic effect while experimenting with a cell made of metal electrodes in a conducting solution. He noted that the cell produced more electricity when it was exposed to light it was a photovoltaic cell.

    In 1954 PV technology was born when Daryl Chapin, Calvin Fuller and Gerald Pearson developed the silicon PV cell at Bell Labs in 1954 the first solar cell capable of absorbing and converting enough of the sun’s energy into power to run everyday electrical equipment.

    Today satellites, spacecraft orbiting Earth, are powered by solar energy.

    How Does Solar Power Work

    • 1.The Sun’s light is absorbed by the solar panels.
    • 2.The silicon and conductors in the panel convert the light into Direct Current electricity, which then flows into the inverter.
    • 3.The inverter converts the DC into Alternate Current electricity, which is used in your home.
    • 4.Any additional electricity that’s not used by your home goes via your home’s meter into the mains power grid for others to use.
    • 5.Electricity is drawn from the grid when you need more power than your solar energy system produces.

    With a grid connected solar system, you are still connected to mains power which supplies your home and school at night and other times when the solar panels aren’t generating enough electricity.
