Grid-tied Photovoltaic Systems are generally the simplest type of system in the field of Solar Power. Without a backup or storage option it works in conjunction with the national grid.
The electricity of grid-tied Photovoltaic Systems must be used immediately. If your PV System produces excess electricity you have two options:
When grid-tied Photovoltaic Systems don’t produce enough Solar Power to cover your consumption, the grid will seamlessly supply your house or business. However, due to a higher potential, your self-produced Solar Power will always be consumed before the grid electricity.
It is important to know that grid-tied Photovoltaic Systems do not produce electricity during a power failure or load-shedding. It requires a reference signal, which is in this particular case the public grid. If you want to have electricity during these times you need to use a Solar Battery System (we call it grid-interactive). The Battery will provide the required reference signal for the Solar Modules and you can still produce and use your electricity.
