Battery Storage For Homes & Businesses in Dorset & Somerset.
The Benefits of Solar PV Battery Storage.
A battery storage system allows you to capture and store the excess energy your solar panels generate during the day so you can use it in the evenings, during peak times, or when it’s cloudy.
This helps you maximise your solar investment, protect yourself from rising energy costs, and increase your energy independence.
Earn Money From Your Solar PV With the Smart Export Guarantee.
Leading Battery Storage Manufacturers You Can Trust.
Increase Efficiency
You may not need to use the energy generated by Solar PV throughout the day. A battery storage system allows you to store the energy so its ready to use when you need it.
Further Reduce Energy Bills
Using stored energy reduces your dependance on the National Grid, further reducing your energy bills.
Earn Additional Income
If you generate and store renewable energy in your home or business, you can feed back any electricity that you don’t use under the Smart Export Guarantee.
Peace of Mind
Battery storage systems can be used to provide a back up for essential power supplies in the event of power outages from the grid.

What Our Customers Say...
Solar Battery Storage FAQs.
What is solar battery storage?
Solar battery storage is a system that stores excess electricity generated by your solar panels for use later – such as at night or during peak usage times. Instead of sending unused solar energy back to the grid, a battery allows your home or business to use more of the energy it produces, increasing your independence from the grid and reducing energy bills. Battery storage can also provide backup power during outages and help you take advantage of time-of-use tariffs by storing cheap electricity to use when prices are higher.
Can I add battery storage to an existing Solar PV system?
Yes, you can retrofit battery storage to an existing solar PV system. Most modern solar setups are compatible with battery add-ons, and there are flexible options available – whether your system is AC- or DC-coupled. Retrofitting allows you to store excess energy instead of exporting it, helping you increase self-consumption, lower your electricity bills, and improve energy independence. At King and Brooks, we’ll assess your current system and recommend the most efficient and cost-effective battery solution for your needs.
How long will a battery storage system last and what maintenance will it require?
Solar battery storage systems typically last 10 to 15 years, depending on the type of battery, how often it’s used, and the quality of the installation. Lithium-ion batteries are now the most common type and tend to offer the best balance of lifespan, efficiency, and low maintenance. Most systems require very little upkeep beyond periodic checks to ensure proper performance. At King and Brooks, we install reliable, long-lasting batteries with manufacturer warranties and offer ongoing support to keep your system running smoothly.
How much does it cost to install a battery storage system?
The cost to install a battery storage system in the UK typically ranges from £3,000 to £8,000, depending on the battery’s capacity (measured in kWh), brand, and whether it’s being retrofitted or installed alongside solar panels. Smaller home batteries (around 5 kWh) are at the lower end, while larger or commercial systems (10 kWh and above) can cost more. Adding smart features or backup capabilities can also increase the price. At King and Brooks, we’ll provide a tailored quote based on your energy needs and help you choose the most cost-effective setup for maximum benefit.
Can I install a battery storage system at both my home and business?
Yes, you can install a battery storage system at both your home and business. Whether paired with solar panels or used on its own to store off-peak electricity, battery storage helps reduce reliance on the grid, cut energy bills, and provide backup power during outages. Systems can be tailored to suit different property types and energy demands – smaller, space-efficient options for homes and higher-capacity systems for commercial sites
Which battery storage manufacturers do you use?
We use leading manufacturers we can trust, such as Tesla, Sunsynk, Solax & Fox
Where is a battery storage system fitted and is it discreet?
Battery storage systems are usually fitted in a garage, utility room, plant room, or outbuilding, but they can also be installed outside in a weatherproof unit. They’re designed to be compact and discreet, with modern systems taking up roughly the same space as a small cupboard or boiler. At King and Brooks, we’ll recommend the best location based on your property, ventilation needs, and access – keeping the installation tidy, safe, and as unobtrusive as possible.
How does a battery storage system connect to the National Grid to export stored energy back?
A battery storage system connects to the national grid through your property’s existing electrical system, using a bi-directional inverter to manage both charging and discharging. When your battery has surplus energy and the grid needs it, the inverter converts the stored DC electricity into AC power for export.
When will i see a return on investment for my battery storage system?
The return on investment for a battery storage system typically takes 7 to 12 years, depending on your energy usage, electricity prices, battery size, and whether it’s paired with solar panels. You’ll see faster payback if you:
- Use most of the energy your solar panels generate
- Take advantage of off-peak tariffs (charging your battery when electricity is cheapest)
- Reduce your reliance on the grid during peak rate times
- Export stored energy back to the grid for payments under schemes like the Smart Export Guarantee (SEG)
How long does it take to install a battery storage system?
Installing a battery storage system typically takes 1 to 2 days, depending on the complexity of the setup and whether it’s being installed alongside solar panels or retrofitted to an existing system. Smaller residential installations can often be completed in a single day, while larger or commercial systems may take a bit longer
