Battery Storage Installers in Swansea & South Wales
Make more use of your solar energy with battery storage designed around your property and electricity use. Based in Swansea, Ulex Energy installs battery systems for homes and businesses across South Wales, including new solar installations and additions to existing systems.
Battery storage for homes and businesses
With new solar panels, a battery stores surplus solar electricity for use later. We design your panels, inverter and battery together, considering when you use electricity, available space and budget. With suitable equipment and an appropriate tariff, charging during cheaper grid periods may also be an option.
For businesses, we assess electricity demand, operating hours and the existing supply alongside solar generation. We design the proposed system around your premises and explain the scope, equipment and expected performance before you commit. Explore our Commercial Solar Panels service for larger projects.
Add a battery to your existing solar panels
Already have solar panels? We can assess the options for adding battery storage to your existing installation.
We review your inverter, electrical setup and energy use before recommending an approach. We explain which equipment can be retained, what needs to be added or changed, and how the proposed system would work.
Battery systems we install
Our installations include equipment from Sigenergy, Tesla, Fox ESS and Fogstar, amongst others. We select equipment around each project’s requirements, including the existing system, storage capacity, installation space and budget.
Fairwater, Cardiff: Solar across three roof aspects, paired with a Fox inverter and 5.2 kWh of battery storage.
Dunvant, Swansea: Solar across two roof aspects with SolaX battery storage.
Uplands, Swansea: A 19-panel Aiko installation with 16 kWh of Fogstar battery storage, planned alongside a future heat pump.

Battery storage questions
Can I add a battery to my existing solar panels?
Often, yes. The installation method depends on your existing inverter and electrical setup. We assess the system first and explain suitable options, including any equipment changes required.
What size battery do I need?
We consider how much electricity you use, when you use it, your solar generation and tariff. These help us recommend suitable storage capacity and power output for your needs.
Will my battery work during a power cut?
Only when the system is specifically designed and installed for backup. What can run, and for how long, depends on the connected circuits, system power and available battery charge. We explain the options in your proposal.
