BENEFITS
Why add battery storage?
Use energy at night
Power your home after dark using solar energy stored during the day.
Reduce grid dependency
Avoid peak tariff hours by drawing from your battery instead of the grid.
Improve energy security
Keep the lights on during power outages with backup battery power.
Maximise solar savings
Use 100% of your solar generation — nothing wasted, nothing exported for pennies.
SOLAR + BATTERY
Better together.
Solar panels generate energy when the sun shines. Battery storage means you use every kilowatt you generate — day and night. The combination typically doubles your bill savings compared to solar alone.
Solar only
Uses solar during the day. Imports from grid at night. Saves ~40%.
Solar + Battery
Uses solar day and night. Minimal grid imports. Saves up to 80%.

Battery Storge FAQ's
Is battery storage worth it in the UK?
For many households, yes. Battery storage allows you to store excess solar energy or cheaper off-peak electricity and use it when energy prices are higher. This can reduce reliance on the grid, improve energy independence and help lower electricity bills over time. The value depends on your energy usage, tariff and whether you already have solar panels.
Can I have battery storage without solar panels?
Modern home batteries can charge from the electricity grid during cheaper off-peak periods and discharge when electricity is more expensive. Many homeowners use battery storage alongside smart tariffs even before installing solar panels.
How long do home batteries last?
Most quality home battery systems last between 10 and 15 years, with many manufacturers offering warranties of around 10 years. Lifespan depends on battery chemistry, usage patterns and installation quality. Lithium Iron Phosphate (LFP) batteries are becoming increasingly popular due to their safety and long cycle life.
What size battery do I need for my home?
The right battery size depends on your household’s electricity consumption and whether you have solar panels. As a guide:
Small homes: 5–8 kWh
Medium homes: 8–12 kWh
Larger homes: 10–20+ kWh
A professional assessment can determine the most suitable size based on your usage patterns.

Can a battery power my home during a power cut?
Some battery systems offer backup power functionality, allowing essential appliances such as lights, internet routers, fridges and selected sockets to continue operating during a power outage. Not all batteries include this feature, so it’s important to check specifications before installation.
How much does battery storage cost in the UK?
Battery storage costs vary depending on capacity and brand, but a typical residential system generally ranges from around £3,000 to £7,000, with larger systems costing more. When paired with solar panels and smart tariffs, batteries can help maximise energy savings and improve energy independence.
