Is a Solar Battery Worth It?

Whether a solar battery is worth it depends on your household, your electricity usage and what you want to get out of your solar system.

For some homeowners, a battery can significantly reduce electricity bills and provide greater energy independence. For others, the upfront cost may outweigh the financial savings, particularly if they already use most of their solar power during the day.

There isn't a one-size-fits-all answer.

When Is a Battery Worth Considering?

A solar battery may be a worthwhile investment if you:

  • Use most of your electricity in the evenings.

  • Want to store excess solar energy instead of exporting it to the grid.

  • Would like backup power during blackouts (with a compatible battery system).

  • Want to reduce your reliance on the electricity grid.

  • Expect electricity prices to continue increasing over time.

On the other hand, if you're home during the day and regularly use appliances while your solar system is generating electricity, you may already be making excellent use of your solar energy without needing a battery.

It Depends on More Than Just Savings

While financial payback is important, many people install batteries for reasons beyond reducing their electricity bills.

A battery can provide greater energy independence, help protect against rising electricity prices and, with the right setup, keep essential appliances running during power outages.

For some households, those benefits are just as valuable as the potential savings.

Estimate Your Battery Payback

If you're wondering whether a battery makes financial sense, the best place to start is by estimating how much of your solar energy you could store and use yourself.

Our Battery Size & Payback Calculator can help estimate the battery size that may suit your home and provide an indication of how long it could take to recover the cost through electricity savings.

If you're planning an off-grid property, our Off-Grid Battery Size Calculator can also help estimate the battery storage you'll need based on your daily energy usage.
