How do Solar Panels work? #

For a standard solar package, photovoltaic (PV) panels are mounted to the roof and connected to inverters on your wall at home, easy as that. The inverter is connected to the house’s switchboard, providing energy from the solar panels to meet your home’s energy needs. When sunlight shines onto the solar panels; electrons inside the panels are knocked free from atoms and generate electricity.

These loose electrons are then captured and move along a circuit, forming direct current (DC) electricity. The DC electricity moves from the solar panels to the inverters on your wall, where DC electricity is converted into alternating current (AC), ready to be used in your home.

The quantity of solar panels you would need depends on: #

  • Your energy usage
  • Your estimated savings and payback period
  • How much sunshine you receive in your location?
  • Angle and orientation of your roof, any potential shading
  • How much energy you consume in the winter/summer seasons
