Is it better to install solar and a battery together?

In many cases, yes — but not always.

Installing solar and a battery together allows for:

  • One integrated system design
  • Correct solar sizing from day one
  • Electrical infrastructure designed once
  • Better long-term flexibility

However, some households are better off installing solar first and adding a battery later. We assess usage patterns, tariffs, budgets, and future plans to recommend the right pathway.

I already have solar — can I add a battery?

Yes, in most cases.

Before adding a battery, we assess:

  • Your existing inverter type and capacity
  • Solar system size and performance
  • Day vs night electricity usage
  • Export limits and feed-in tariffs
  • Switchboard and compliance requirements

This ensures the battery delivers real value, not just storage capacity.

How do I know if a battery is worth it for my home?

A battery is most valuable when:

  • You use a lot of electricity in the evening or overnight
  • Feed-in tariffs are low
  • Export limits restrict how much solar you can send to the grid
  • Backup power is important
  • You’re planning EV charging or electrification

We review your data and explain whether a battery makes financial and practical sense for your situation.

What size battery do I need?

There’s no one-size-fits-all answer.

Battery size depends on:

  • Household energy usage patterns
  • Solar production surplus
  • Desired backup capability
  • Budget and future plans

Oversizing a battery doesn’t always improve outcomes. We size batteries to maximise return on investment and usability.

Can a battery provide backup power during outages?

Some battery systems can provide backup power, but this must be designed correctly.

Backup capability depends on:

  • Battery and inverter type
  • Whether backup circuits are installed
  • Total load during an outage

We’ll clearly explain what backup is possible, what isn’t, and how to design it properly if resilience is a priority.

Should I design solar bigger than my current usage?

Often, yes.

Many households underestimate future electricity needs, especially if they plan to add:

  • EV charging
  • Heat pump hot water
  • Electric heating and cooling
  • Induction cooking

Designing solar with future usage in mind can avoid costly upgrades later.

Can I add an EV charger later?

Absolutely — and we plan for it.

We often design solar and battery systems to be EV-ready, even if the charger is installed later. This includes considering electrical capacity, load management, and system integration.

Is solar and battery part of going fully electric?

Yes — solar and batteries are often the foundation of an all-electric home.

They support future upgrades such as:

  • Heat pump hot water
  • Electric heating and cooling
  • Induction cooking

A well-planned system makes electrification simpler and more affordable over time.
