From when I calculated it was about 4.5-5y payback on just solar, and 7-8 years with battery system.
We have a solar water diverter so using gas when gas rates are cheaper, and intend to heat the tank at night with cheap electricity if gas rates go higher than electric.
If you plan to move home in the next 7 years then solar + battery is unlikely to be worth it financially, as I don’t think solar panels are priced into property sale values.
Might make it more desirable for purchase though going forwards, as lower bills and lower energy performance ratings might become more important purchase requirements.
