Adding A Battery To Existing Solar
If you already have solar panels, adding battery storage does not mean starting again. Retrofitting works with your existing inverter setup in most cases, and our engineers confirm compatibility before any work is booked. A retrofit typically means a new hybrid battery unit wired into your current system, with no changes needed to the panels themselves.
What Retrofit Day Involves
Retrofit day itself is straightforward. Our engineers arrive, fit the battery and hybrid inverter in a suitable ventilated location such as a garage or utility room, wire it into your existing solar supply, and test the full system before leaving. Every job is quoted in full before any work is booked, so there are no surprises once work starts.


Payback And Tariff Savings
A retrofit battery makes the most of energy you are currently exporting to the grid for a low rate, storing it instead for use later in the day or overnight. For households on an export tariff, this can meaningfully change the payback period on the original solar investment, particularly as electricity prices rise. We are happy to answer questions at any point before, during, or after the work is carried out.
Why Choose Us For A Retrofit
Retrofit installations are carried out by the same MCS certified engineers who handle new solar and battery systems, so you get the same standard of work regardless of when your original panels were fitted. We talk you through the finished system on handover, so you know exactly how to get the most from it. Pricing is agreed upfront and never changes once work has started, whatever the job uncovers.
