Rooftop solar photovoltaic (PV) systems convert energy from the sun into electricity you can use in your property. Any electricity you don’t use gets fed into the main electricity grid.
Large-scale batteries can be connected to solar PV systems to store energy generated during the day. This energy can be used at night or in poor weather when the system isn’t generating much energy.
Using the electricity generated by a solar PV system during daytime hours means you don’t need to buy as much electricity from the grid, which can help lower your electricity bills. Where possible, align your electricity consumption, like running clothes washers, dishwashers, or heating and cooling, to times when your solar generation is highest, rather than running them at night when you have to buy electricity from the grid.
