Solar Battery Storage Installers
Energy Wise Solar provides professional Duracell solar battery storage installations across Lancashire and the surrounding counties, helping homes and businesses store excess solar energy and reduce reliance on the grid.
Benefits of Solar Battery Energy Storage
Solar battery storage offers significant benefits for homeowners looking to get more from their solar PV system. By storing excess electricity generated during the day, a battery allows you to power your home in the evening and at night.
This can increase solar self-consumption from around 30–40% without a battery to up to 70–80% with battery storage, depending on usage patterns and system size. Higher self-consumption means less electricity imported from the grid, helping to reduce energy bills and improve overall returns on your investment. Any surplus energy you don't use or store can still be exported back to the grid, allowing you to benefit from export payments while maintaining greater energy independence.
How Do Solar Battery Storage Systems Work?
A simple, seamless cycle that keeps your home powered day and night.
Generation
Your solar PV panels generate clean electricity from sunlight.
Distribution
The electricity is first used to power your home, meeting your daily energy needs.
Storage
Any surplus energy not immediately used is stored in your Duracell battery, ready for later use.
Power
When the sun isn't shining, at night or on cloudy days — your battery powers your home, reducing reliance on the grid.
Grid Backup
If your energy needs exceed what your solar panels and battery supply, electricity is seamlessly drawn from the grid.
Reduce Your Dependence on the Grid
Solar battery storage allows you to make the most of your solar energy, giving you access to free electricity even during the evening and night.
By storing excess energy, you can maximise the return on your solar panels while significantly reducing your reliance on the grid.
At Energy Wise Solar, we specialise in Duracell battery systems, offering a range of capacities to suit every household. Every home and energy need is unique, so our expert surveyors will assess your property and recommend the ideal system tailored specifically for you.

Battery Storage FAQs
Common questions about solar battery storage, the Duracell Dura5, and what to expect from installation.
A solar battery storage system stores excess electricity generated by your solar panels during the day, so you can use it in the evenings, at night, or during periods of low solar output. Without storage, any surplus energy that your home doesn't immediately use is exported back to the national grid.
With battery storage, that surplus energy is captured and held in your battery, ready to be used whenever your panels aren't generating enough — such as in the evenings, overnight, or on overcast days. This means your home can run on clean, self-generated electricity for more of the day.
The result is a significant increase in your solar self-consumption rate and a meaningful reduction in the amount of electricity you need to import from the grid.
Without a battery, a typical solar system covers around 30–40% of your home's electricity needs, as you can only use what your panels are generating at that exact moment. Adding a Duracell battery can increase this to 70–80%, dramatically reducing the amount of electricity you need to purchase from the grid.
Actual savings vary depending on your household energy usage, the size of your solar array, the battery capacity, and your energy tariff. Households that use more energy in the evenings or have high overall consumption tend to benefit most from battery storage.
Over time, a battery can also help protect you from future energy price increases by reducing your reliance on grid electricity.
We exclusively install Duracell Dura5 5.12kWh home storage batteries. The Dura5 is a compact, wall-mounted unit suitable for most domestic properties and designed to integrate seamlessly with a wide range of solar inverter systems.
Key features of the Duracell Dura5 include a 1C/1C charge and discharge rate, a free monitoring app for iOS and Android, UK-based technical support, and a modular design that allows you to stack multiple units to increase your total storage capacity — up to 32 units if required.
The Duracell Dura5 carries a 10-year product warranty, providing long-term peace of mind that your energy storage investment is protected.
Yes, in most cases a battery can be retrofitted to an existing solar PV system. This is known as an AC-coupled installation, where the battery connects to your home's electrical system independently of the existing solar inverter.
Our engineers will assess your current setup during a free site survey and advise on the most suitable connection method and battery capacity for your home. The Duracell Dura5 is designed to integrate with most inverter types, making it a flexible choice for retrofit installations.
If you already have solar panels and are looking to get more from your system, adding a battery is often one of the most cost-effective upgrades you can make.
While solar battery storage works best when paired with solar panels — as it allows you to store your own free electricity — it is possible to install a battery system without panels. In this case, the battery can charge from the grid during off-peak hours when electricity tariffs are lower, and discharge during peak periods to reduce costs.
However, the greatest financial and environmental benefits are achieved when battery storage is combined with a solar PV system. If you don't currently have solar panels, we can design and install a combined solar and battery system tailored to your home and energy needs.
Our team will advise on the best configuration for your situation during a free, no-obligation survey.
A battery-only installation can typically be completed in half a day to a full day, depending on the connection type and the complexity of your existing electrical setup. If battery storage is being installed alongside a new solar PV system, both installations are usually completed together within one to two days.
Before installation, our team will carry out a site survey to assess your property and confirm the most suitable installation approach. On the day, our engineers will mount the battery, complete all electrical connections, commission the system, and walk you through how to use the monitoring app.
We always aim to minimise disruption and leave your home clean and tidy after every installation.
