It allows for time-shifting power, charging from solar, providing grid support, and exporting power back to the grid. When an ESS system is able to produce more power than it can use and store, it can sell the surplus to the grid; and when it has insufficient energy or power, it automatically buys it from the grid.

PV panel power ratings typically fall between 250 watts and 400 watts. Simple arithmetic tells us that a 10kW solar system will require 25 to 40 panels. Calculating the area of a 3.25′ x 5.5′ panel, you will get 17.875 sq. feet per panel. Multiplying this by 25 and 40, we get 446.875 sq. feet and 715 sq. feet, respectively.
