Got Solar But Still Buying Power?

A Battery is your solution

Got solar, but still opening your electricity bill every month, wondering what happened? You're not alone. Many Sydney households generate plenty of solar energy during the day but buy expensive grid electricity once the sun goes down. A solar battery lets you store the excess energy your system produces and use it when your home needs it. With federal battery rebates reducing upfront costs, there has never been a better time to get more value from your existing solar system.
Since 2007, Stag Electrical has helped Australian homeowners maximise their solar investment through tailored battery solutions designed for long-term performance, energy independence and lower electricity bills.

Sydney Solar Works Hard.
A Battery Makes It Work Smarter.

Sydney homes can generate strong solar power during the day, but much of that excess energy is often exported before it can reduce evening electricity costs.

A solar battery stores unused daytime power so you can use it after sunset for lighting, appliances, heating, cooling and everyday energy needs.

Why Sydney Homeowners Add Batteries What It Helps With
Store More Solar Keep excess daytime energy and use it later.
Lower Grid Use Buy less electricity back at night.
Improve Savings Many Sydney households may save $1,000–$2,000+ per year.
Use Available Rebates Eligible systems may receive up to 30% off upfront battery costs.
Cover Evening Demand Use stored solar for heating, cooling, appliances and lighting.
Increase Energy Control Rely less on retailers, feed-in tariffs and rising power prices.

Is Your Sydney Solar
Ready For A Battery?
If your Sydney solar system is generating power during the day but your electricity bills are still too high, battery storage may be the missing piece. These are the signs your home could benefit from adding a solar battery.

You Already Have Solar Panels

If your system is producing excess energy during the day, a battery can store that power so you can use it after sunset.

Your Sydney Power Bills Are Still High

Many Sydney households still buy expensive grid electricity at night, even when their solar system works well during the day.

You Export More Solar Than You Use

If most of your solar power is being sent back to the grid for a low feed-in tariff, a battery can help you keep more of that value at home.

You Use More Energy At Night

Households with evening appliance use, heating, cooling, lighting or EV charging can often get more value from stored solar energy.

You Want More Energy Control

A solar battery can help reduce reliance on the grid and give your Sydney household more control over when and how your solar power is used.

What our customers say

“I am saving money with my panels, I’m very excited to say. The quoting process was so easy, and no pressure. Price-wise they were the most competitive, and not only are the panels and inverters great and really high-quality, but the team was so great to work with that I have no hesitation in recommending them.”

“The speed that they got a quote to me – and had the system erected – was super-fast. They were straight to the point, legitimate; I could get them on the phone, and not beat around the bush with a salesperson. They were polite and enjoyable to have around. Get Stag to do it – I’d recommend them any day of the week.”

Frequently Asked Questions: Sydney Solar Batteries

Talk to a Verified Installer No pressure! Just expert advice

Is a solar battery worth it in Sydney?

A solar battery can be worthwhile for Sydney households that already have solar but still use a lot of grid electricity at night. It allows you to store excess solar energy during the day and use it after sunset, helping reduce reliance on expensive grid power.

Can I add a battery to my existing Sydney solar system?

Yes. Many existing Sydney solar systems can be upgraded with battery storage, depending on your inverter, switchboard, available space and current system setup. Stag Electrical can assess your existing solar system and recommend a suitable battery solution.

Why are my Sydney electricity bills still high if I already have solar?

Your solar system may be generating most of its power during the day when your household is not using it. Without a battery, excess energy is often exported to the grid for a low feed-in tariff, while you buy electricity back at night for a higher rate.

What size solar battery do I need for my Sydney home?

The right battery size depends on your solar system, evening electricity usage, household demand, tariff, budget and whether you want backup power. A properly sized battery should match your energy habits rather than simply being the biggest option available.

Are solar battery rebates available in Sydney?

Eligible Sydney households may be able to access federal battery rebate support, depending on current program rules and eligibility requirements. Stag Electrical can help explain which rebates may apply at the time of your battery installation.

Do solar batteries provide backup power during outages?

Some solar batteries can provide backup power during outages, but this depends on the battery model, inverter setup and whether backup functionality is included in the installation design. Stag Electrical can recommend a system based on your backup power needs.
