Batteries store surplus energy so you save on electricity bills

• A battery storage installation helps to manage electricity consumption efficiently. Batteries integrate with renewable generation such as solar PV, acting as a store for surplus electricity generated on site rather than exporting it. Without battery storage solar PV owners can find themselves selling energy to the grid for 4p per kWh only to buy it back again later in the day for 15p per kWh. Obviously this makes no sense.
