Solar panels generate electricity whenever the sun is shining, but that doesn’t necessarily coincide with when your household uses the most power. A solar battery can bridge that gap by storing surplus electricity produced during the day so you can use it later in the evening or overnight rather than drawing power from the grid.
That can help you use more of the renewable electricity your solar panels generate and potentially reduce your energy bills. Some batteries can also be charged from the grid when electricity is cheaper, giving households on time-of-use tariffs another way to manage their energy costs.
