  • Why solar + batteries + heat pumps can work so well together

Do you actually need solar panels to make a home battery worthwhile? Solar might get most of the attention, but the battery could be doing some of the most important work in your energy system.

In this episode of Charged Up, Simon Wray and Justin Canning break down how battery storage really works, why correctly sizing a battery matters and how batteries can potentially make sense even without solar panels.

They explore how batteries can store excess solar generation for later, charge using cheaper off-peak electricity and then supply that energy when grid electricity is more expensive.

The episode also looks at backup power, load shifting and why simply buying the biggest battery available isn’t necessarily the smartest decision.

The key takeaway? Battery storage isn’t simply an add-on for solar anymore. It’s increasingly about giving homes and businesses greater control over when they buy, store and use electricity.
