is dependent upon your municipality's electrical grid. The DC electricity generated by the photovoltaic (PV) panels is sent through a grid-tied inverter, which converts it to AC power that's compatible with the grid.
What is grid tied solar system?
What's included:
● Grid Tied Inverter
● MC4 Connector
The reality is all electricity produced by panels is automatically fed into the electric company’s meter, where it is under the control of the electric company. You have to read the fine print in your specific locality to determine whether you have a net metering or net purchase and sale agreement.
The downside to grid-tied systems is you’re still at the mercy of the electric company. As mentioned above, electric companies in many areas are aggressively adding fees and reducing buy prices to make solar users responsible for the extra strain placed on the grid.
