Battery Storage
Battery storage allows you to store unused solar energy generated during the day and use it when you need it most, including in the evenings and during peak-rate periods.
At NRG Solar, we supply and install a range of battery storage solutions designed to suit different properties, lifestyles and energy demands. Whether you are installing a brand-new solar system or improving an existing setup, battery storage can significantly improve how your home uses energy.
Instead of exporting excess electricity back to the grid immediately, a battery system stores that energy for later use. As a result, homeowners can reduce reliance on expensive grid electricity and make greater use of the energy their solar panels generate.
We supply systems from leading manufacturers including Tesla, Sigenergy and other trusted battery storage brands known for reliability, smart controls and long-term performance.
Battery storage can be installed:
- Alongside a new solar system
- As part of a larger home energy upgrade
- In some cases, as a retrofit to an existing solar installation
Why More Homeowners Are Installing Battery Storage
With electricity prices continuing to fluctuate across the UK, more homeowners are looking for ways to improve energy independence and reduce long-term costs.
Battery storage helps by:
✔ Storing excess daytime solar generation
✔ Reducing electricity imported from the grid
✔ Supporting smarter use of off-peak tariffs
✔ Improving overall solar self-consumption
✔ Providing greater control over household energy usage
Additionally, some battery systems can integrate with smart tariffs such as those offered by Octopus Energy, allowing homeowners to charge batteries overnight at lower electricity rates.

Battery Storage for Existing Solar Systems
If you already have solar panels installed, adding battery storage can help increase the value and efficiency of your existing system.
Many older solar systems export large amounts of electricity back to the grid during the day. However, without storage, that energy may not be available when your home needs it most.
A retrofit battery system allows you to store more of your own generation and use it later in the evening, overnight or during higher-cost peak periods.
Our team will assess:
- Your current solar setup
- Daily household usage
- Available installation space
- Future energy requirements
This ensures the battery system is correctly sized and configured for long-term performance.
