NeedTo know before Connecting yoursolar power system to the grid

Connecting your home to the grid will require involvement from you and the provider of your solar panel system.
For starters, your solar system provider must know the local interconnection laws. The interconnection laws are rules and procedures that specifically apply to situations where a renewable energy system such as a solar energy system is "plugged" into the power grid. The interconnection laws state the terms that must be followed by both solar energy system owners and utilities. In order to get started with a grid-tied system, your solar system provider will file interconnection and net metering applications to the utility company.
