Grid Connect Solar Systems

A grid connect system collects DC electricity from the sun through the solar panels fitted to the roof, and this DC electricity travels through an inverter which converts it to AC power into the household. In cases where the system provides more energy than the house requires during the day, the remainder is supplied to the electricity grid through a fitted bi-directional net meter. When power is supplied to the mains grid, this effectively winds your electricity meter backwards, and the home owner receives a credit or payment for that electricity, called a feed-in tariff.

The following diagram shows a typical Grid Connect System.

During daylight hours, a correctly designed grid connect system should be providing the majority of all of your electrical needs for the household and very little should be fed back into the grid. During the night when your system does not produce any electricity you draw your power from the grid and your electricity meter measures your consumption.

If there is a blackout, your grid connect system will automatically shut down in order to prevent feeding back into the grid, which could be potentially dangerous to utility workers repairing the electricity grid. This means that even though you have a solar system, during a blackout you will not have power available. If you want to have a continuous power supply during a blackout then you would need to have back up batteries installed or a backup generator.

All PV modules and Inverters supplied by Towards Tomorrow Energy are tested, certified and approved by the Clean Energy Council.
