The most common residential and commercial solar system
Grid connected solar systems are installed on sites that have regular electricity supply to the site through grid mains. These systems use a grid approved inverter designed to meet the main grid requirements such as voltage, safety, anti-islanding (to disconnect solar power source if mains grid is down) and other supply characteristics such as single phase, three phase etc.
A grid connect solar system works in the following way:
- Sunshine on the solar panels generates DC (Direct Currentelectricity
- This DC electricity generated is fed into a solar grid-inverter that converts it to 240V 50Hz AC electricity to match the mains characteristics
- This 240V AC electricity is supplied / used to power appliances in your home
- Any unused or Surplus electricity is fed back into the main grid
Grid connect systems form the bulk of Australia’s solar industry mainly due to the convenience and complimentary role played by the grid connect systems. If solar power produced is in excess of consumption requirement, the excess energy is fed back to the grid (most grid suppliers have a mechanism of paying the solar system owner for this excess power sent to the grid).
If the solar power generated is insufficient to meet the consumption requirements, then grid mains is used to fill the gap.
When the solar cells are not producing power, for example at night, your power is supplied by the mains power grid as usual. The energy retailer charges the usual supply rate for the power used depending on the time of use (TOU).
