Battery Storage (EESS)
Store your electricity to use when it suits you
Batteries let you store electricity (either generated from solar panels or purchased at cheap rate) so that you can use it when you want i.e at night when panels are not producing or when your energy usage is high at peak rate times of the day. It’s one of the best ways to increase self-consumption, reduce reliance on the grid, and add resilience for your home.
What Is Solar Battery Storage?
Solar battery backup (also called home battery storage) stores surplus solar energy instead of exporting it to the grid. When your home needs power later, the battery supplies it—meaning you buy less electricity from your supplier.
Some systems can also provide backup power during a power cut (optional, depending on system design).

Key Benefits of a Solar Battery Storage
Use More of What You Generate
Most homes use a large chunk of electricity in the evening—exactly when solar panels produce less. A battery bridges that gap.
Lower Your Electricity Bills
By using stored solar and/or charging strategically (i.e in lower tariff periods), you can reduce the amount of peak rate electricity you import from the grid
Protection Against Rising Energy Prices
The more energy you generate and store, the less exposed you are to price increases.
Backup Power During Outages (Optional)
If configured for backup, a battery can keep essential circuits running during a power cut—like lights, Wi-Fi, fridge/freezer, or medical equipment.
Do You Need a Battery If You Already Have Solar?
If you already have solar panels, a battery is often the fastest way to improve overall performance by increasing self-consumption.
You’ll usually benefit most if:
- You’re out during the day and use more electricity in the evening
- You want to reduce grid import and improve energy independence
- You’re planning to add EV charging or a Heat Pump
- You want backup resilience for key appliances

Frequently Asked Questions : Solar Batteries
Yes. Solar panels generate electricity from daylight, even on cloudy days — output is lower than summer but still effective.
Most panels last 25+ years, with performance warranties typically covering long-term output.
Yes. Many systems are installed battery-ready so storage can be added in the future.
Most domestic solar installations fall under permitted development. We’ll advise if your property is different.
Most residential installations are completed within 1–2 days.
