The good news is – yes, you can usually install battery storage to an old solar panel installation!
If you had solar panels installed years ago, it’s a great idea to consider adding modern battery storage now to make better use of your solar energy. Adding a solar battery is a great way to increase your energy independence, reduce your reliance on the grid, and cut your electricity bills even further.
How does battery storage work with existing solar panels?
A solar battery stores excess electricity that your panels generate during the day. Instead of sending surplus energy back to the grid, you can store it and use it later, such as in the evening or during peak-rate periods.
If your solar system was installed without a battery, you can usually retrofit a storage system without major changes. At Intelligent Energy Solutions, we install Duracell Energy battery storage systems, which work seamlessly with both new and older solar installations.
Will my existing solar system definitely support a battery?
In most cases, yes. The key factors we check include:
Type of Inverter – Some older inverters may need an upgrade or an additional hybrid inverter to work with a battery.
System Size – The more solar power your system generates, the more energy you can store.
Current Feed-in Tariff (FIT) – If you’re on an older FIT scheme, adding a battery won’t affect your payments, but you should still check how much excess energy you’re exporting.
Why upgrade now?
✔️ Lower Energy Bills – Store solar energy and use it when needed.
✔️ Energy Security – Protect yourself from rising electricity costs.
✔️ Government Incentives – Grants and financing options can help make the switch more affordable.
