Battery Storage Systems
Store Your Energy. Reduce Bills. Power Your Home Smarter.
Battery storage systems allow you to store electricity for use when you need it most. Whether paired with solar panels or used alongside grid electricity, battery storage gives homeowners greater control over energy usage, lowers reliance on the grid, and supports a cleaner, more sustainable future.
AEG Construction designs and installs reliable, high-performance battery storage systems tailored to your property and energy goals.
What Is a Battery Storage System?
A battery storage system captures electricity and stores it for later use when needed most. This electricity may come from renewable sources such as solar panels or from the national grid during off-peak hours when tariffs are lowest.
Instead of exporting unused solar energy at low rates or buying expensive peak-time electricity, you can store power and use it when household demand and prices are highest, maximizing savings and energy independence.
Battery Storage with Solar Panels
Pairing battery storage with solar PV allows you to use more of the electricity you generate. Instead of exporting surplus solar energy, you store it and use it in the evening or during cloudy periods.
This combination significantly increases overall system efficiency and return on investment.
Standalone Battery Storage
Battery systems can also be installed without solar panels as a standalone energy management solution. These systems store cheaper off-peak electricity from the grid during night hours and release it during peak tariff periods, reducing energy costs.
This approach helps reduce energy costs substantially while preparing your home for future renewable upgrades. When you're ready to add solar panels later, the battery infrastructure is already in place, making the transition seamless and cost-effective.
How Battery Storage Systems Work
Electricity is generated by solar panels or drawn from the grid.
Excess electricity is stored in the battery.
When energy is required, the battery releases stored electricity to your home.
The system automatically switches between grid, solar, and battery power for optimum efficiency.
Are Battery Storage Systems Efficient?
Modern lithium-ion batteries are highly efficient, typically delivering over 90% round-trip efficiency. This means very little energy is lost during charging and discharging.
With proper sizing and design, a battery storage system can provide long-term performance and consistent savings.
