A professionally designed system can meet most consumers’ electric need.A professionally designed system can meet most consumers’ electric need. The grid-tied PV system where the electric grid acts as a battery is the simplest and most cost-efficient way to add solar production to your home or business.

With this system, the generated power satisfies the consumer’s power needs when the sun is bright, and the extra generated power is sent to the grid by running the electric meter backwards. At night when the sun has gone down, the grid satisfy the needs of the consumer. In perfect conditions, this back-and-forth exchange of kw/h will resultin zero electric consumption or a zero electric bill at the end of the month. This is call net-meeting.

Since nothing is perfect 100% of the time, there will be some months when the PV system would produce less than the home or business uses, and the grid will provide the rest.In these conditions, the customer will receive an electric bill.
