Why Install Solar Battery Storage?
Without a battery, any solar electricity you do not use straight away may be exported back to the grid. With a battery, you can store more of that unused electricity and use it later in the day or evening.
Battery storage can help you:
Use more of your own solar power
Reduce electricity taken from the grid
Improve the value of your solar PV system
Support evening and night-time electricity usage
Prepare for EV charging
Improve energy independence
Make better use of off-peak tariffs where suitable
A battery does not replace good system design. The battery size should be matched to your solar PV system, electricity usage and future plans.
Battery Storage for Existing Solar Panels
Already have solar panels? We can assess your current system and advise whether battery storage can be added. Many existing solar PV systems can be upgraded with battery storage, depending on the inverter, available space, cable routes and electrical setup.
During the survey, we can check:
Existing inverter type
Consumer unit and electrical supply
Space for battery installation
Cable routes
Solar generation
Typical household usage
Monitoring options
Whether AC-coupled or hybrid battery options may be suitable

Battery Storage with New Solar Panels
If you are installing solar panels for the first time, it is worth considering battery storage during the design stage. Installing solar and battery storage together can make the system cleaner, easier to plan and better suited to your property.
A combined solar and battery system can be designed around:
Your roof size
Daily energy use
Evening energy demand
EV charging plans
Future heat pump use
Available installation space
Monitoring and control

Home Battery Storage
Home battery storage is ideal for households that want to make better use of their solar panels. It can be especially useful for families, people working away from home during the day, homes with high evening usage and properties with electric vehicles.
A home battery can usually be installed in a garage, utility area, loft space if suitable, cupboard or external location depending on manufacturer requirements and installation conditions.
Commercial Battery Storage
Businesses can also benefit from battery storage, especially where electricity usage changes throughout the day. Battery storage may help commercial properties reduce peak demand, make better use of solar generation and support energy management.

FAQs
Can I add a battery to my existing solar panels?
In many cases, yes. We would need to check your existing inverter, consumer unit, available space and system setup before recommending the right battery option.
What size battery do I need?
The right battery size depends on your solar generation, electricity usage, evening demand and future plans such as EV charging or heat pump installation.
Will a battery power my whole house in a power cut?
Not all battery systems provide backup power during a power cut. Backup function depends on the battery, inverter and installation design.
Is solar battery storage worth it?
Battery storage can be worthwhile if you generate unused solar electricity or use most of your energy outside daylight hours. A site survey helps confirm whether it makes sense for your property.
Can battery storage work without solar panels?
Yes, some battery systems can charge from the grid, but most customers get the best value when battery storage is combined with solar PV.
