The "PV" stands for photovoltaic.
It means that the solar system is used to generate electricity (as opposed to solar pool heating systems, for example, that simply heat water, and don't generate electricity).
The solar PV system can be grid-connected or stand-alone. Connecting the solar PV system to the grid allows any excess electricity produced to be fed back into the mains system, for other households to use and for you to save more money.
