How Do Solar Panels Work

Solar Energy

Solar Energy is one of the main sources of renewable green energy which is continuously being replenished by nature - our Sun. The sunlight and solar heat radiated to earth are being absorbed, dispersed and converted to other forms of energy. With the use of technology we are able to harness the power of the sun that reaches the surface of the earth.

How Solar Works

Photovoltaic systems use the sun's energy to create electricity. Solar panels convert the solar energy to electric energy when the solar energy displaces electrons within the solar panels. The displaced electrons are used to create direct current electricity. We then use an inverter to convert this direct current (DC) electricity to alternating current (AC) electricity that is used in most homes or businesses.

Solar electric systems are renewable energy sources which allow the owners to generate electricity from the Sun.

Here's the breakdown of what happens:

  • The Sun's energy hits the solar panels creating DC electricity
  • The DC electricity flows through the conductors into an Inverter, which then converts that energy into AC electricity
  • The AC electricity is first used onsite
  • Any excess energy not used onsite is pushed back to the utility grid, creating a bank of kilowatt hours to be used later

Fact: The earth receives more energy from the sun in one hour, than the world uses in an entire year.

Advantages of Solar Power are:

  • Solar energy is free and abundant energy supplied by nature itself
  • Solar energy systems are environmentally friendly - as an alternative green energy source
  • Solar energy is free energy that is saving our fossil fuels and saving the planet by using natural resources that are available
  • You off-set negative impacts on the earth, and offset pollutants such as carbon dioxide
  • Solar panels (photovoltaic PV panels) can be easily placed in residential areas (residential solar panels) in on or off grid installations
  • Solar panels cost has been falling and is expected to continue on a diminishing turn in the future; this means that PV panels will gradually become economically more viable - not in need of any subsidy incentives.
