Effect of installing a battery on the PS: Installing a battery in the building causes the excess PV energy to be stored in the battery during non-peak hours, and during peak hours, instead of taking power from the grid, the energy stored in the battery is used to supply the building load and causes peak shaving. The simulation results back up this claim, as the
