Why add battery storage to your solar PV system?
Provide back-up power for security
Lots of properties across the UK and beyond have frequent power cuts and it's possible this will become more of an issue in years to come.
Adding battery storage for back-up will secure you against power cuts.
Back-up power systems can be more expensive than simply adding storage to increase self-consumption but this entirely depends on how long you will need to rely on the battery system.
