⚡ Battery Storage Costs
Home battery storage systems typically cost £2,000–£5,000 in the UK in 2026, depending on capacity and brand.

Adding battery storage to a solar system increases self-consumption from around 30% to 70–80%, significantly improving the economics of solar panels. Most homeowners pair battery storage with existing or new solar installations.

Always get at least 3 quotes from MCS-certified installers. Check gov.uk for current grants before committing.

Why Add Battery Storage to Your Solar System?

Solar panels typically generate most electricity during the middle of the day when many households are at work and consumption is low. Without storage, that surplus electricity is exported to the grid (via the Smart Export Guarantee) for a modest payment.

A home battery stores that surplus electricity so you can use it in the evening — when consumption is higher and solar generation has stopped. This increases self-consumption — the proportion of your solar generation that you use yourself — from around 30% to 70–80%, making the solar system much more economical.
