How Does Solar Works

Grid connect System convert Energy from the sun into Electricity via Solar panels mounted to your roof, which can be used to power your home.

 

  • The sun shines on the solar panels generating DC (Direct current) electricity, most houses in Australia are connected to the grid so AC (Alternating current) electricity is used.
  • We use an inverter to convert the DC current from the panels into AC into our house.
  • AC electricity is used to power appliances in your home.

Any excess energy will be fed back into the main grid.

HOW DOES SOLAR WORKS

TYPES OF SOLAR PV SYSTEMS

We have gather this information from the Clean Energy Council for your knowledge.

 A Solar PV System is made up of a mounting frame with PV modules and an inverter that converts the power from DC (direct current) to AC (alternating current), so it can be used in your home or exported back to the grid.

GRID-CONNECTED SOLAR PV SYSTEMS

This is the most common form of solar system installed in Australia. Most suburban homes in Australia are connected to the electricity grid, which uses alternating current electricity (AC). The inverter converts the electricity generated by the solar system – which is direct current (DC) – into AC electricity so that the power generated is compatible with the grid and ordinary business needs. Most houses with grid-connect solar systems use solar power fi rst before sourcing electricity from the grid. When the panels are not producing electricity at night, electricity is supplied from the electricity grid.

GRID-CONNECT WITH BATTERY BACK-UP SOLAR PV SYSTEMS

Grid-connect PV systems with battery back-up (sometimes referred to as uninterrupted power supply or hybrid solar PV systems) are becoming increasingly popular. With solar customers in many states now receiving a low price for electricity sold back to the grid, battery back-up systems can be a viable alternative as they use the electricity stored during the day to run your house at night. They also have the advantage of being able to supply power during power outages.

STAND-ALONE SOLAR PV SYSTEMS

Stand-alone systems are not connected to the electricity grid and typically are installed in remote areas where there is limited connection to the grid, or areas of low electricity demand. Unlike their grid-connected counterparts, these systems must have batteries or back-up generation to provide supply at night. In many cases they will also include a diesel or petrol generator to supplement energy supply.
