Grid Connect

What is a grid connect solar power system?

Grid connect systems, often located in built up areas, supply solar electricity through an inverter directly to the household and to the electricity grid if the system is providing more energy than the house needs. When power is supplied to the mains grid, the home owner usually receives a credit or a payment for that electricity. This is called a feed in tariff.

Any size grid connect solar power system will reduce your yearly power consumption and your power bill. Naturally, the bigger the system, the bigger the benefit. Many people are convinced that solar PV is far to expensive and too complicated. This is simply not true. Making the move to solar PV is a smart financial investment and simple to manage.

The installation for a typical household is usually completed in a day. Once installed the system will generate electricity during daylight hours, day in, day out for domestic use or to feed back into the  grid, even if nobody is home. In the event of a blackout, your system will automatically disconnect from the grid, keeping your home safe and sound.

 

How does it work?

While the technology behind solar energy may seem difficult to grasp, but when broken down, how solar power works is quite easy to understand – particularly in a grid connect scenario as this only requires a few components installed in your home or business.

  • The sun shines on the solar panels generating DC electricity
  • The DC electricity is fed into a solar inverter that converts it to 240V  AC electricity.
  • The 240V AC electricity is used to power appliances in your home.
  • Surplus electricity is fed back into the main grid.

If a grid connect system is producing more power than is being consumed, the surplus is fed into the mains power grid. Some electricity provides will meter the electricity fed into the grid by your system and provide a credit on your bill.
(Yes thats right ….  they pay you for the excess electricity you produce.

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 rate for the power used.
