Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers.

How to connect a PV solar system to the utility grid

Now, the main breaker can be changed to a smaller size (e.g. de-rated) to make room for more solar. Here is an example of a de-rated electrical panel to handle a larger solar system: (BUSBAR RATING x .20) + (BUSBAR - MAIN OCPD) = MAX PV (A) (200A x .20) + (200A - 175A) = 65A MAX BACKFEED SOLAR. De-rating the main breaker to 175A in this …
