How Does a Solar Farm Connect to the Grid?
All solar farms connect to a specific point on the electrical grid, the vast network of wires that connects every power generation plant to every home and business that consumes power. That point is called the "point of interconnection," or POI. The POI is different for utility-scale versus community solar scale projects.
