On-Grid Solar PV System

The solar system is on-grid if it is connected to your local utility’s Grid. For anyone, this simply means that your utility system serves as a battery. In the process of Net metering, if solar system produces more energy with your solar panels or system than you consume, the excess energy is delivered to your grid’s power company, allowing you to build credit that you may pay out at the end of the year. Being grid-tied has the advantage of not requiring the purchase of a costly battery backup system to store any excess energy.
