Is Battery Storage Actually Worth It?

Battery storage is becoming one of the biggest talking points in the domestic Solar market and for good reason.

For many homeowners, installing Solar PV is the first step towards reducing electricity bills and becoming less reliant on the grid. But increasingly, people are now asking the next question: “How do I make even better use of the energy I generate?”

That’s where battery storage comes in.

Rather than exporting excess electricity back to the grid during the day, a battery allows you to store unused Solar energy and use it later, typically in the evening, overnight, or during periods when electricity prices are at their highest.

But is it actually worth the investment?

The answer depends on how your home uses energy, your existing system setup, and what your long-term goals are.

How battery storage works in real terms

Without battery storage, most homes generate the highest amount of Solar energy during the middle of the day when many people are out at work and using very little electricity.

That often means a significant portion of generated energy is exported back to the grid.

With battery storage, that unused electricity can instead be stored and used later when the home actually needs it most.

In practical terms, this can help:

• Reduce evening electricity costs

• Increase the amount of Solar energy used within the home

• Lower reliance on peak-time electricity

• Improve overall energy independence

• Provide greater control over energy usage

  
  

For some homeowners, battery storage can also provide backup functionality during power outages depending on the system design and equipment installed.

When battery storage makes the most sense

Battery storage is particularly effective for households that:

• Use more electricity in the evenings

• Are out during the daytime

• Have high electricity usage overall

• Want greater protection against rising energy prices

• Already have Solar installed and want to maximise performance

• Are interested in long-term energy independence

  
  

We’re also seeing more homeowners choose battery-ready systems from the outset, even if they don’t install the battery immediately. This allows them to expand later as energy usage or budgets change.

What homeowners should consider before installing

Like any energy investment, battery storage should be properly assessed based on the property and household usage patterns.

Some of the key things to consider include:

• Current electricity usage: Understanding when and how your home consumes electricity is one of the biggest factors in determining whether a battery will deliver strong value.

• Existing Solar system performance: Battery storage works best when paired with a well-designed Solar PV system that is generating sufficient excess energy during the day.

• Battery size: Bigger isn’t always better. The goal is to design a system that matches the household’s usage profile rather than oversizing unnecessarily.

• Future plans: If you’re considering an EV, heat pump or increased electricity usage in future, battery storage may become even more valuable over time.

• Long-term goals: For some people, the priority is purely financial savings. For others, it’s about resilience, energy independence and reducing reliance on the grid.

So… is it worth it?

For many homeowners, yes.

Battery storage is helping households take greater control of how and when they use electricity, while improving the overall value of their Solar PV system.

And as electricity prices continue to fluctuate, more people are seeing battery storage not just as an add-on, but as part of a wider long-term energy strategy.

At Solmatix, we always recommend looking at the full picture, your home, your usage, your goals and your future plans before deciding what system is right for you.
