Solar batteries Adelaide trusts. Installed by an award winner.

We install Sigenergy, AlphaESS, and GoodWe batteries, and we’re a Sigenergy Excellent Installer of the Year award winner, recognised directly by the manufacturer for the quality of our installs.

Why add a battery

Your panels generate power all day. Without a battery, most of it isn't yours after dark.

If you’ve already got solar panels, you’ll know the gap: your system generates the most power in the middle of the day, when you’re often not home to use it. Without storage, that surplus gets exported to the grid for a feed-in tariff that’s typically a fraction of what you pay to buy power back at night.

A battery closes that gap. It stores what your panels generate during the day so you can use it in the evening instead of paying retail rates for grid electricity, and depending on your setup, it can keep essential circuits running if the grid goes down.

We install Sigenergy, AlphaESS, and GoodWe batteries, and we’re a Sigenergy Excellent Installer of the Year award winner, recognised by the manufacturer itself, not a badge we awarded ourselves.

Find out if a battery actually pays off for you

Every home’s payback period is different. Call us and we’ll run the real numbers for your usage, not a generic estimate.

The economics

Why store your solar instead of exporting it?

Every household’s numbers are different, but the underlying logic is the same, here’s what a battery actually changes about how your solar system works for you.

Use your own power, not the grid's

Feed-in tariffs are typically well below retail import prices. A battery lets you store daytime solar and use it in the evening instead of buying it back at full price.

Blackout protection capability

Our battery systems include blackout protection capability, so stored power can keep your home running through a grid outage rather than leaving you in the dark.

Future-proofs your system

Adding storage now means you're set up for an EV charger or higher household usage later, without redesigning your solar system from scratch.

What you're getting

What an award-winning battery install actually includes.

A battery is only as good as its install. Here’s what separates a properly configured system from a box bolted to a wall.

Sigenergy award-winning installation

We're a Sigenergy Excellent Installer of the Year award winner, recognition from the manufacturer for installation quality, not a badge we gave ourselves.

10-year manufacturer warranty

A genuine warranty from Sigenergy, AlphaESS, or Q.HOME, not a vague promise from an importer who may not exist in 10 years' time.

Blackout protection capability

Our installs include blackout protection capability, so stored power can keep your home running through a grid outage. We'll confirm exactly how that works for your setup.

Pairs with any existing solar system

New install or retrofit: we assess your current panels and inverter to confirm compatibility before recommending a battery and size.

App-based monitoring

Watch your battery charge, discharge, and state of health from your phone, with full monitoring set up and explained before our team leaves.

Sized to your actual household

We size the battery from your real usage and budget, not a generic package, so you're not paying for capacity you'll never use, or under-sizing and missing the value.

From first call to a battery on
your wall: usually a single day.

Why Bright Earth Solar

Recognised by the manufacturer, not just claiming to be.

Plenty of installers say they’re “battery specialists.” We’re a Sigenergy Excellent Installer of the Year award winner, an award given by Sigenergy itself, based on real installation quality and customer outcomes, not a badge anyone can put on their website.

Complete your system

A battery works best as part of a complete system.

We design panels, inverters, and batteries together as one system, not as separate add-ons sold later by someone else.

AIKO & Risen Solar Panels

No solar yet? A battery still works, but pairs best with your own panels generating the power it stores. We design both together for the best return.

Fronius & GoodWe Inverters

Your battery needs to talk to a compatible inverter. We specify Fronius and GoodWe inverters matched to your battery and panel array, not whatever’s cheapest that week.

What customers say

100+ five-star reviews from real Adelaide homeowners.

Common questions

Everything you wanted to know about solar batteries.

What battery brands does Bright Earth Solar install?

Sigenergy, AlphaESS, and Q.HOME. We chose these three for proven performance and genuine manufacturer warranties, not because they're the cheapest batteries on the market. We can also work with sonnen on request, just ask.

What warranty comes with the battery?

Every battery we install carries a 10-year manufacturer warranty. We also stand behind our own installation workmanship, so you're covered on both the product and the install.

Can I add a battery to my existing solar system?

Yes. A battery pairs with any existing solar system, new or old. We assess your current inverter and panel setup to confirm compatibility and recommend the right battery size.

Is a solar battery worth it in Adelaide?

For most solar households, feed-in tariffs are well below what you pay to import power from the grid. A battery lets you store your own excess solar and use it after dark instead of exporting it for a few cents, which is where the value comes from.

What finance options are available for a solar battery?

$0 deposit finance options are available with fast approval. Many customers add a battery using finance and offset some of the repayment with the electricity they stop buying from the grid.

Why does the Sigenergy award matter?

Bright Earth Solar is a Sigenergy Excellent Installer of the Year award winner, recognised directly by the manufacturer for installation quality and customer outcomes, not a generic industry badge anyone can claim.

Does a solar battery give me blackout protection?

Our battery systems include blackout protection capability, so your home can keep running on stored power during a grid outage. We'll confirm exactly how that applies to your setup as part of your quote.

How is a battery sized for my home?

It depends on your household's evening usage, your existing or planned solar system size, and your budget. We size it from your actual usage rather than a generic package.

What's the difference between Sigenergy, AlphaESS, and Q.HOME?

All three are reputable battery manufacturers with genuine warranties. We'll recommend one based on your budget, household size, and whether blackout protection or maximum storage capacity matters more to you.

How much does a solar battery cost in Adelaide?

Solar battery prices vary by brand and storage capacity, generally landing in the low-to-mid thousands installed. We price each battery based on your home's actual usage and existing solar system rather than a flat number. If you're comparing solar battery installers near you, ask for the same level of detail in every quote.
