Ready to Cut Your Power Bills?

If you’re considering solar, knowing how much you could save is a great place to start. This guide walks you through the steps to estimate your annual electricity bill savings and choose the right system size for your home.

Step 1: Find Your Annual Electricity Usage

Start by reviewing your last 4 electricity bills and add up the total kilowatt-hours (kWh) used—or look for the yearly total listed by your provider. This figure is key to sizing your solar system.

Step 2: Estimate the Right System Size

Based on your usage and the size of your home, here’s a guide to choosing a realistic solar system size:

Note: The bigger the system, the more STC (rebate) credits you’ll receive—so larger systems often offer better value over time.

Step 3: Estimate Your Solar Production

In Brisbane, solar panels generate about 4.2 kWh per kW per day. Multiply that by your system size and then by 365 to get your estimated annual output.

Example for 6.6kW system:

 6.6 × 4.2 × 365 = ~10,100 kWh per year

Step 4: Estimate Your Electricity Bill Savings

Now take your estimated annual solar output and multiply it by your current electricity rate (e.g. $0.28 per kWh).

Example:

 10,100 kWh × $0.28 = ~$2,828 in potential annual bill savings*

*Actual savings may be lower depending on usage habits and feed-in tariff rates, especially if you’re not using the power during the day.

Step 5 (Optional): Consider Adding a Battery

Adding a battery allows you to store your unused solar energy for use at night—further reducing reliance on the grid. From July 1, 2025, the Cheaper Home Batteries Program offers a 30% rebate on home battery installations, making this option more affordable.

Final Thoughts

Solar isn’t one-size-fits-all. Your savings depend on how much electricity you use, your roof size, and when you use power during the day. But with Brisbane’s sunny climate and generous rebates, the payback period for solar is getting shorter every year.

Making the Switch to Solar

In early 2024, the Thompsons decided to take control of their energy costs by installing a 6.6kW solar system through Solenergi. With around 40% of their energy usage during daylight hours, they were able to directly consume a large portion of the power generated from their panels.

After switching to solar, the Thompsons’ annual energy bill plummeted. In fact, thanks to Queensland’s feed-in tariffs and smart daytime usage, they are now in credit most months, with estimated first-year savings of over $1,200.

The Next Step: Battery Storage

To take things even further, the Thompsons have decided to add a 10kWh battery, made more affordable through the federal government’s Cheaper Home Batteries Program—a rebate of 30% off the upfront cost. With the battery storing their excess daytime solar energy for use at night, their reliance on the grid is expected to shrink dramatically.

Once the battery is installed, their total electricity bill is forecast to drop to around $150 per year. That’s a saving of approximately $1,410 annually compared to their pre-solar expenses.

The Results: Real Savings for Real Families

Why It Works

Daytime Usage: 40% of power used during the day, directly from solar
Smart Feed-in Tariff: Extra energy exported = extra credit
Battery Storage: Reduced grid reliance at night
Rebates & Incentives: Helping make clean energy affordable

Over 20 years, systems like this are projected to save homeowners more than $16,000 in power bills, with a 6–7 year payback period even without including environmental benefits.

Environmental Impact

Choosing solar doesn’t just make financial sense—it’s also better for the planet. A typical 6.6kW solar system like the Thompsons’ saves each year:

• Equivalent to planting 202 trees
• Avoids burning 3,362 litres of petrol
• Saves 3,821 kg of coal from being burned

As electricity prices continue to rise and solar feed-in tariffs decline in Queensland, more homeowners are turning to solar battery storage to maximise their solar power investment and reduce reliance on the grid.

What Is Solar Battery Storage?

A solar battery stores excess electricity generated by your solar panels during the day. Instead of sending this surplus energy back to the grid for a small credit, the battery saves it for use when the sun isn’t shining—like at night or on cloudy days. This means you can power your home with solar energy around the clock, increasing your energy independence and reducing your electricity bills.

Why Add a Battery to Your Solar System?

Adding a battery to your solar installation offers several benefits:

• Lower Electricity Bills: By using stored solar energy during peak times, you can reduce the amount of electricity you need to purchase from the grid.
• Energy Independence: With a battery, you’re less affected by grid outages and price hikes, giving you more control over your energy usage.

• Maximised Solar Investment: Storing excess solar power ensures you make the most of your solar panels, especially as feed-in tariffs decrease.

• Environmental Impact: Using more of your own solar energy reduces your carbon footprint and supports a cleaner energy future.

In Queensland, where feed-in tariffs are decreasing and electricity prices are on the rise, these benefits are particularly significant.

New Federal Rebate Makes Batteries More Affordable

Starting 1 July 2025, the Australian Government’s Cheaper Home Batteries program offers a 30% rebate on eligible solar battery installations. This initiative aims to reduce the average cost of a battery from over $10,000 to around $6,000, making it more accessible for households and small businesses. The rebate applies to batteries installed alongside new or existing solar panels and is available for systems between 5kWh and 100kWh. It’s important to note that the rebate’s value will decrease annually from 2026, so early adoption can maximise your savings.

Is Solar Battery Storage Right for You?

If you already have solar panels or are considering a new solar installation, adding a battery can enhance your system’s efficiency and provide greater energy security. With the new federal rebate and rising energy costs, now is an opportune time to invest in solar battery storage.

What Is the Cheaper Home Batteries Program?

The Australian Government is offering households and small businesses around a 30% discount on the upfront cost of small-scale home batteries. The idea is to make it easier for more Australians to store the solar power they generate during the day, so they can use it later—like at night or on cloudy days.

This initiative is part of the Small-scale Renewable Energy Scheme (SRES), which is also behind the current incentives for installing solar panels. Now, the scheme is expanding to include batteries, and it’s all backed by federal government funding.

How Can You Benefit?

At Solenergi, we’re here to help you make the most of this opportunity. If you’re already enjoying solar energy from your rooftop system, adding a battery can take your solar power setup to the next level. Here’s how:

• Slash your electricity bills by using stored solar power at peak times 
• Cut carbon emissions by relying less on the grid and gas-powered energy 
• Get up to $4,000 off the upfront cost of a battery 
• Save up to $1,600 a year on your energy bills 

The discount is calculated based on the usable capacity of your battery. For example, a typical 11.5 kWh battery that used to cost around $13,000 could now cost closer to $9,000.

Why Add a Battery to Your Solar System?

Right now, only about 1 in 40 Australian homes with solar panels have a battery. That means most solar owners are sending excess energy back to the grid without being able to use it themselves later. By storing your own solar energy, you’re not only saving more—you’re also helping to reduce demand on the energy network.

Solenergi will guide you through the entire process—from eligibility checks and product selection to installation and claiming your discount through the SRES.
