Pairs perfectly with solar PV for maximum savings
Understanding the Technology
What is Battery Storage?
A home battery storage system stores electricity for later use. If you have solar panels, a battery allows you to keep the energy you generate during the day and use it in the evening when the sun is not shining. Without a battery, that excess energy simply goes back to the grid for a relatively low payment.
Even without solar panels, a battery can save you money by charging during off-peak hours when electricity is cheaper (such as overnight on certain tariffs) and discharging during peak times when rates are highest. This is called load shifting and can significantly reduce your bills.
Modern battery systems are compact, quiet, and designed for indoor or outdoor installation. They integrate seamlessly with your home electrical system and can be monitored and controlled via smartphone apps, giving you complete visibility and control over your energy use.
Battery Storage Systems Let You:
- Store excess solar energy instead of exporting it back to the grid
- Use stored energy during peak rate hours to reduce electricity costs
- Provide backup power during grid outages (with compatible systems)
- Reduce your carbon footprint by maximising renewable energy use
- Smart controls allow you to optimise charging and usage patterns
- Compatible with most existing solar PV systems
The Technology Explained
How Does Battery Storage Work?
Understanding how your battery system captures, stores, and releases energy to power your home.
01
Solar Generation
During daylight hours, your solar panels generate electricity. Any power not immediately used by your home is directed to charge the battery instead of being exported to the grid.
02
Energy Storage
The battery stores excess electricity in lithium-ion cells, similar to a large version of the battery in your phone. Modern systems can store 5-15kWh or more, enough for hours of typical home use.
03
Smart Management
An intelligent inverter manages the flow of electricity, automatically deciding when to charge from solar, when to discharge to power your home, and when to draw from the grid if needed.
04
Evening Use
As the sun sets and your solar production drops, the battery automatically takes over, powering your lights, appliances, and heating with the energy stored during the day.
Maximise Your Solar Investment
Without a battery, a typical home uses only 30-50% of the solar energy it generates. The rest is exported to the grid for around 4-5p per kWh. With a battery, you can use 70-80% or more of your solar generation, using energy that would cost you 25-35p per kWh to buy back.
Why Add a Battery
Benefits of Battery Storage
Discover why adding battery storage to your home makes sense, whether you have solar panels or not.
01.
Increased Savings
Use more of the solar energy you generate instead of selling it cheaply to the grid. The difference between export rates and import rates means significant savings over time.
02.
Greater Energy Independence
Reduce your reliance on the grid and protect yourself from rising energy prices. The more of your own energy you use, the less vulnerable you are to market fluctuations.
03.
Off-Peak Tariff Benefits
Even without solar, charge your battery overnight at cheap rates (as low as 7p/kWh on some tariffs) and use that energy during expensive peak periods.
04.
Backup Power Option
Some battery systems can provide power during grid outages, keeping essential appliances running. Peace of mind during storms or planned maintenance.
05.
Smart Home Integration
Monitor and control your battery from your smartphone. See exactly how much energy you are generating, storing, and using in real-time.
06.
Long Lifespan
Quality batteries are designed to last 10-15 years with thousands of charge cycles. Many come with warranties of 10 years or more.

We Understand Your Concerns
Many homeowners worry about disruption and changes to their home. Here is how we address the most common concerns.
Adding to Existing Solar
If you already have solar panels, we can retrofit a battery to your existing system. We assess compatibility with your current inverter and recommend the best approach.
Installation Location
Batteries can be installed indoors (garage, utility room) or outdoors in weatherproof enclosures. We find the best location considering cable runs and accessibility.
Electrical Capacity
We check your consumer unit and supply capacity to ensure it can handle the battery. If upgrades are needed, we include this in your quote upfront.
Future Expansion
Many battery systems are modular, meaning you can add more capacity later. We can advise on systems that allow for easy expansion if your needs grow.

How much does a home battery storage system cost?
Battery costs vary depending on capacity and brand. A typical home battery system (5-10kWh) costs between £4,000 and £8,000 including installation. Larger systems or premium brands like Tesla Powerwall can cost more. We provide detailed quotes after assessing your specific needs and energy usage patterns.
Can I add a battery to my existing solar panels?
Yes, in most cases we can retrofit a battery to an existing solar PV system. We assess your current inverter to determine the best approach. Sometimes we can add an AC-coupled battery that works alongside your existing inverter; other times it may be more efficient to upgrade to a hybrid inverter that manages both solar and battery.
How long will a home battery last?
Quality home batteries are designed to last 10-15 years and come with warranties typically covering 10 years or a certain number of charge cycles (often 6,000-10,000 cycles). After this time, the battery does not stop working but may have reduced capacity, similar to an old phone battery.
What size battery do I need?
The right size depends on your energy usage, solar generation (if applicable), and goals. A typical home uses 8-10kWh per day, but evening/night usage when solar is not generating is often 4-6kWh. We analyse your usage patterns and recommend a size that balances cost with benefit.
Will a battery power my home during a power cut?
It depends on the system. Some batteries can provide backup power during outages, but this requires specific equipment and configuration. Standard grid-tied systems switch off during power cuts for safety reasons. If backup power is important to you, let us know and we can recommend suitable options.
Do I need solar panels to have a battery?
No, batteries can be beneficial even without solar. You can charge from the grid during off-peak hours (as low as 7p/kWh on some tariffs like Octopus Go) and use that stored energy during peak times (often 25-35p/kWh). This ‘load shifting’ can save significant amounts over a year.
Where will the battery be installed?
Batteries can be installed indoors (garage, utility room, under stairs) or outdoors in weatherproof enclosures. The best location depends on your home layout, proximity to your consumer unit, and available space. We discuss options during the survey and recommend the most practical solution.
How much can I save with a battery?
Savings depend on your energy usage, tariff, and whether you have solar. With solar, a battery can increase self-consumption from around 30-50% to 70-80% or more. Without solar, load shifting on a variable tariff can save £200-400 annually. We provide estimated savings based on your specific situation.
What brands of battery do you install?
We install batteries from leading manufacturers including GivEnergy, Tesla Powerwall, SolaX, and Fox ESS. We recommend brands based on your specific needs, budget, and compatibility with any existing equipment. All brands we work with have proven reliability and strong warranty support.
What happens to the battery at the end of its life?
Battery systems can be recycled. The lithium-ion cells contain valuable materials that can be recovered and reused. When the time comes to replace your battery, we can arrange responsible disposal and recycling of the old unit. Some manufacturers have take-back programmes.
