BATTERY STORAGE · KENT
Store your solar. Use it when you need it.
Home battery storage lets you keep more of the electricity you generate and use it later, including in the evening when your solar panels aren’t generating. We install new battery systems and can upgrade many existing solar installations across Kent.
What is home battery storage and how does it work?
Home battery storage lets you store electricity generated by your solar panels instead of sending all the excess back to the grid. You can then use that stored energy later, such as in the evening when your solar panels are no longer generating.
This can help you use more of your own solar electricity and reduce the amount of power you need to buy from the grid.
Why consider adding
battery storage?
Solar panels often generate more electricity during the day than your home needs at that moment. A battery gives you the option to store some of that excess energy and use it later, rather than buying as much electricity back from the grid when your solar generation falls.
The right battery depends on how much electricity you generate, when you use it and how much surplus solar you normally export. We look at your actual energy use before recommending whether battery storage makes sense for your home.
Use more of your own solar
Store surplus solar electricity during the day so you can use more of it later when your panels are generating less.
Add storage to an existing system
Already have solar panels? Battery storage can be added to many existing systems. We’ll assess your current setup and recommend the most appropriate way to integrate it.
Expand as your needs change
Compatible battery systems can be designed with future expansion in mind, giving you the option to increase storage capacity if your electricity use changes.
Honest battery sizing
A bigger battery isn’t automatically a better investment. We look at your generation, consumption and export patterns to recommend appropriate storage capacity.
Frequently Asked
Questions
View AllCan I add a battery to my existing solar panels?
In many cases, yes. You don’t need to have had your original solar system installed by Solec. We’ll assess your existing panels, inverter and electrical setup and explain what’s compatible, what may need changing and the most appropriate way to add storage.
Can I install a home battery without solar panels?
Yes. A battery can be installed without solar panels and charged from the grid. With an appropriate time-of-use tariff, you may be able to charge the battery when electricity is cheaper and use the stored energy during more expensive periods. Whether this makes financial sense depends on your tariff, electricity use and system configuration.
What size home battery do I need?
It depends on how much electricity you use, when you use it and, if you have solar, how much surplus electricity your panels generate. We look at your actual usage rather than simply recommending the largest battery available. We’ll also consider future demand such as an EV or heat pump.
Is battery storage
right for my home?
Battery storage can make sense if you regularly generate more solar electricity than you use during the day, or if much of your electricity use happens later when your panels are generating less.
The right answer depends on your solar generation, electricity consumption, existing equipment and tariff. We look at these together before recommending whether a battery is worthwhile and what size is appropriate.
Could be right for you if:
- You regularly export surplus solar electricity that you could potentially store and use later
- You use a lot of electricity in the evening, after your solar generation has fallen
- You already have solar panels and want to increase how much of your own generation you use at home
- You’re installing a new solar system and want battery storage included from the outset
- Your electricity needs may increase, for example if you’re considering an EV or heat pump

What does a home battery
installation involve?
Assess
We look at your electricity use, existing solar system if you have one, and what you want battery storage to achieve.
Design
We recommend an appropriate battery capacity and system configuration based on your property, energy use and existing equipment.
Quote
You’ll receive a clear, itemised quote explaining the proposed battery system and installation. No “today-only” pressure.
Install
The Solec team installs and commissions your battery system, connects it to the appropriate equipment and completes the required electrical checks and certification.
Set up & handover
We’ll help set up your system monitoring, show you how to use it and explain how your battery has been configured.
Your home battery
questions, answered
How much does home battery storage cost in Kent?
The cost depends on battery capacity, your existing solar and electrical setup and whether additional equipment is required. As a UK guide, Energy Saving Trust puts a typical 5kWh battery system at around £4,600, although battery costs vary considerably depending on the system. Solec will recommend appropriate capacity for your home and provide a clear, itemised quote following assessment.
How much could a home battery save me?
There isn’t one reliable savings figure that applies to every home. Your savings depend on how much surplus solar electricity you generate, when you use electricity, your import and export tariffs, battery capacity and whether you use lower-cost off-peak electricity to charge the battery. We’ll look at your actual energy use and, where available, solar generation and export data before recommending whether battery storage makes financial sense.
Can I add a battery to my existing solar panels?
In many cases, yes. You don’t need to have had your original solar system installed by Solec. We’ll assess your existing panels, inverter and electrical setup and explain what’s compatible, what may need changing and the most appropriate way to add storage.
Can I install a home battery without solar panels?
Yes. A battery can be installed without solar panels and charged from the grid. With an appropriate time-of-use tariff, you may be able to charge the battery when electricity is cheaper and use the stored energy during more expensive periods. Whether this makes financial sense depends on your tariff, electricity use and system configuration.
What size home battery do I need?
It depends on how much electricity you use, when you use it and, if you have solar, how much surplus electricity your panels generate. We look at your actual usage rather than simply recommending the largest battery available. We’ll also consider future demand such as an EV or heat pump.
How long does a home battery last?
A typical home battery has an expected lifespan of around 10–12 years, although this varies according to the battery, how it’s used and operating conditions. The manufacturer’s warranty is separate from expected lifespan, so we’ll explain the warranty applying to the specific battery system proposed for your home.
Can I add more battery capacity later?
Potentially, yes. Compatible expandable battery systems can allow additional storage capacity to be added as your energy needs change. If future expansion is important to you, we’ll take that into account when designing the initial system.
What happens after my battery is installed?
Once your battery system is installed and commissioned, we’ll help you get set up with system monitoring so you can see how your battery is charging, storing and supplying electricity to your home. We’ll explain how the system has been configured and make sure you know how to access the information you need before we leave. If you need help afterwards, Solec remains your point of contact for system checks, fault finding, repairs and future upgrades.
