How do Solar Panels Work.

For many, solar energy can seem too technical and scientific which may put you off investing in solar. However, it is not as confusing as it may seem, we have broken it down in to two parts for you.

Part One: The Solar Panel.

There are many different arrays of solar panels, different companies sell panels with diverse technological advances and kilowatts. An example of this is some companies have upgraded their panels to have PERC technology. PERC stands for ‘Passivated Emitter and Rear Contact’, these solar cells are modified conventional cells that enable the cells to produce 6 to 12 percent more energy than conventional solar panels. Therefore, upgrading your system to produce more energy and save you more money.

Nonetheless, all panels work the same way.

For solar panels to work, they must be exposed to sunlight, which we will always have. The sun releases packets of energy down to our earth called photons, these photons hit the solar cells and form an electrical circuit by knocking electrons loose from their atoms. When these electrons flow through the electrical circuit, they generate electricity.

Part Two: The Inverter.

In solar panels, DC (direct current) electricity is formed by the electrons flowing in a regimented order. However, the electricity we use to power our devices and appliances is called AC (alternating current) electricity, with AC the electrons can flow however they like, non-regimented. Therefore, the solar industry had to find a way to covert the DC to AC, this is where your inverter comes into play. Once the DC is converted to AC, your inverter will transfer the electricity its produced to your home or if you have batteries and they need charging, it will charge them.

In short;

  • Sunlight will shine on your panels.
  • The panels will switch the suns energy to DC electricity.
  • The DC electricity will flow through to your inverter.
  • Your inverter converts DC to AC.
  • The electricity is now ready to use and will automatically power your home.
