Costs
How much do battery storage cost?
Battery prices depend mainly on capacity and whether you are fitting solar at the same time.
| What | Typical cost |
|---|---|
| Standalone battery, 5 to 10 kWh | £3,500 to £7,000 |
| Battery fitted alongside new solar | £2,500 to £5,000 |
Typical ranges for guidance only. Your installer's survey sets the real price.
Savings
What could you save?
Without a battery most homes use around 40% of their solar power. With one, that can rise to around 75%, because daytime power is saved for the evening.
Paired with a smart overnight tariff (around 8p per kWh), a battery can also charge cheaply at night and cover your peak time use, even in winter when solar is low.
Typical extra savings are £150 to £450 a year. Warranties usually run for 10 to 12 years.

Battery storage questions
Can I add a battery to my existing solar panels?
Yes. Most batteries can be retrofitted. Your installer will check your inverter and may suggest a hybrid inverter or an AC coupled battery.
Is a battery worth it without solar?
It can be if you are on a time of use tariff, because you charge cheaply overnight and avoid peak rates. The saving is smaller than with solar.
What size battery do I need?
Most homes suit 5 to 10 kWh. A good installer will look at your usage, not just sell the biggest one.
Will a battery keep my lights on in a power cut?
Only if it is set up with backup or islanding. Ask your installer, as it is not standard on every system.
How do I pay for it?
Most people pay the installer directly. Ask your installer about payment options.
