How does a grid-connected system work?

A grid-connected solar panel system is a conversion and distribution system that connects solar panels to the electricity grid. It is also referred to as a grid-tied solar power system.

The solar panels convert the sun’s energy into electrical energy DC (direct current). This DC energy is then sent to an inverter, which converts the energy into AC (alternating current), the type of electricity that is used in our homes and businesses.

Once the inverter converts the DC energy to AC energy, it is ready to be used by the home or business. However, before it can be used, the system monitors the energy requirements of the building and compares it to the energy being produced by the solar panel system. If the solar panels are producing more energy than currently being used by the home or business, the excess is then directed to the electricity grid, which allows other people in the area to use the energy.

In contrast, when the solar panels are not producing enough energy, the grid will supply the additional energy required. This ensures that energy is always available for the home or business when needed.

In a grid-connected solar panel system, net metering is used to measure the energy that is sent back to the grid versus the energy that is being used from the grid. This allows the homeowner to receive a credit for the excess energy that is produced by their solar panels, which can reduce their electricity bills.
