Connecting a solar energy system?

An interconnection is an electric connection between a utility's grid and a private generation system (PGS). A PGS, also known as Distributed Generation (DG), has the capability to send energy to the utility's energy grid.
Interconnection applications are required for all private generation systems (PGS) supplying energy to the electrical grid. As a residential or business customer, you have the choice to work with a professional contractor to submit an application or submit the application on your own.
Usually, contactors complete and submit the required application on behalf of their clients. The application asks technical information that an experienced contractor will know how to provide.
Submitting your own interconnection application?
A smaller generation system is often large enough for a residential household. The technical way of describing these smaller systems is that they, "distribute less than 10MVA". MVA stands for Mega Volt Amps, which is a measurement used to express the total energy load of a system.

In contrast to smaller generation systems, larger generation systems distribute greater than 10 Mega Volt Amps (MVA). These systems are usually on the wholesale scale. Have you ever seen a large building or open space with rows of large solar panels? These are likely larger generation systems.
