How Much Do Solar Panels Cost in Brisbane?

The cost of a solar panel installation in Brisbane is worth each and every penny! If you can pay your electricity bill every quarter, you can afford a payment plan for a solar install… and start saving money on electricity thereafter!

Okay… but just how much are we talking about here, when it comes to investment? How much can you really expect to save on your electricity bill – and how long will it take for a solar installation to ‘pay back itself’?

Even with government rebates and installer discounts; as a customer, you’re likely to invest thousands of dollars for a solar installation in Brisbane. On average, you can expect to pay between $4,500 to $10,000 to cover the roof of your Brisbane home with solar panels.

Having solar panels is an asset to you and your property, whichever way you look at it – however, it’s also normal to want to know more about solar, before you spend thousands on an installation.

So… Are Solar Panels ‘Worth It’ in Brisbane?

Absolutely, yes!

To guarantee that your solar panels are a worthwhile investment, it’s recommended that your chosen location receives at least four hours of peak sunlight. A peak sun hour is described as an hour in the day when the intensity of the sunlight reaches 1 kilowatt per square metre.

Australia is one of the sunniest places in the world – making Brisbane a prime candidate for solar energy installations. Year after year, the sun provides us with enough solar radiation to power all of our Australian homes and businesses – more than 10,000 times over! Yet according to Geoscience Australia, only about 0.1% of Australia’s energy consumption can be attributed to solar power.

Switching to solar energy is an opportunity that more Australians should take advantage of – if they knew what was best for the planet and their back pocket! Especially in Brisbane, which enjoys 7.5 average daylight hours and 5.4 peak sun hours.

Brisbane residents and businesses have access to a consistency of sunlight that allows their solar systems to output electricity optimally. This is why it’s a ‘no-brainer’ to get solar panels installed on your Brisbane property!

How Much Money Can I Save With Solar?

Let’s say that you pay around $150 for your monthly electric bill, or about $1,800 per year. That’s the average QLD electric bill for a household that uses between 19kWh to 20kWh per day, and consumes the most electricity during midday. 

You may think: “$1,800 per year isn’t that bad compared to the $5,700 price tag of a 5kW solar installation!”

We agree that ‘numbers don’t lie’ – so let us give you some more. Let’s suppose that you spent your hard-earned $5,700 on a solar system. We could be very strict – considering bill inflation and other factors that can affect savings and energy generation efficiency… but let’s just go with the basics, as we are only looking at the first year of savings.

You were moderately lucky, and found that you can install your solar panels on a 30-degree roof pitch angle in a northeastern orientation. It’s not an optimal ‘direct north’ orientation, but it’s still an excellent orientation.

With this solar installation setup, you can generate as much as 19kW of electricity, produced and used during the day. This setup will save you as much as $1,440 per year on your electric bills – meaning that you will only pay around $30 for electricity per month, from here on out.

How Many Panels Are Required to Power My House?

The number of required solar panels varies from home to home; it entirely depends on personal energy consumption and the efficiency of your chosen panels. You’ll need fewer panels when you use more efficient monocrystalline panels – but you’re also paying more per panel in comparison to less efficient polycrystalline panels.

When it comes to how many solar panels you need: it’s not so much the number of panels that you should pay attention to… rather, it’s the overall capacity of your system that counts. For most Australian households, a 5 kW to 6.6 kW solar panel system is enough to reduce electricity bills by as much as 50% to 100%.

To get a good feel on what capacity of a solar panel system you need, collect your electricity bills and get your average daily kilowatt-hours (kWh) consumption. Divide this by the number of peak sun hours you get in your location, and you’ll get the rough system size that you need to power your home. A typical Australian home uses around 20 kWh per day. In Brisbane, where the peak sun hours are at 4.0 hours minimum, 20 kWh divided by 4.0 peak sun hours equates to a 5.0 kW system.

This is just a rough estimate, as other factors come into play… such as the slope of your roof, the orientation of your solar panels, and when you use your power. Contact us online or at 1300 800 991 – we can give you a free solar quote depending on your consumption and location.

What Impacts the Price of Solar Panel Systems?

Solar panel system costs depend on overall efficiency, the type of solar panels you’re using, power output, labor costs, solar panel accessories, and solar incentives. Let’s break down each of these factors:

How Much Rebate Can I Expect to Get for Solar Installations?

The REC registry has a solar rebate calculator, which allows you to see how much of a rebate you can get for small solar installations. It requires the following inputs:

  • Type of generation unit (wind, solar, or hydro)
  • Installation date
  • Power output of the system in kW
  • Deeming period (maximum of 10 years in 2021, with decrements of one year for every year after 2021)
  • Postcode

For example, a 5kW solar power generator installed in Brisbane in 2021 with a deeming period of 10 years will grant you 69 STCs. The value of STCs or small-scale technology certificates fluctuate multiple times in a year, but the latest average is around $37.50.

This table shows the rebates you can get for Brisbane solar installations in 2021 if the STC value remains at $37.50:

Rated Power Output Number of STCs Estimated Savings
5.0 kW (example) 69 $2,587.50
5.4kW 74 $2,775.00
6.0kW 82 $3,075.00
6.6kW 91 $3,412.50
7.0kW 96 $3,600.00

How Much Would Solar Panels Cost for my Commercial Property?

How much you spend on your solar panels will depend on how much energy you’re trying to produce. How much energy does your commercial property consume? Are you looking at solar power solutions to lessen your utility spending, or do you want to operate completely independently of commercial power companies?

Let’s say that your business needs 30 kWh of energy per day. A 28-panel 7kW solar system in an ideal northern orientation in Brisbane can help you produce about 28kWh per day. This setup will set you back an average of $7,500. 

Below are the typical sizes and costs of solar panel systems in Brisbane, and how much energy you can expect them to produce based on their orientation:

System Size Cost North Facing South Facing West or East Facing
3 kW $3,800 – $4,800 12.0 kWh 8.9 kWh 10.6 kWh
5 kW $4,200 – $7,200 20.0 kWh 14.8 kWh 17.6 kWh
6.6 kW $5,000 – $10,000 26.4 kWh 19.5 kWh 23.2 kWh
7 kW $5,500 – $10,500 28.0 kWh 20.7 kWh 24.6 kWh
10 kW $7,900 – $12,900 40.0 kWh 29.6 kWh 35.2 kWh

How Long Does it Take for Solar Panels to Pay for Themselves?

An efficient, quality solar installation in Brisbane takes about five years to pay for itself, and most solar panel cost calculators agree. The below table shows the average time it takes off to pay a solar power investment in Brisbane, for different system sizes.

System Size Cost Yearly Energy Savings Return on Investment in Years
3 kW $3,800 – $4,800 $750 – $1,000 4.8 – 5.0 years
5 kW $4,200 – $7,200 $850 – $1,750 4.0 – 5.0 years
6.6 kW $5,000 – $10,000 $1,320 – $2,100 3.8 – 4.8 years
7 kW $5,500 – $10,500 $1,450 – $2,200 3.8 – 4.8 years
10 kW $7,900 – $12,900 $2,250 – $2,900 3.5 – 4.5 years

The average solar panel system has a lifespan of about 25-30 years. A quality installation can save you about $44,360 to $55,200 over the course of 25-30 years

Besides – solar panels don’t just stop working when they hit 30! They’re simply likely to be less efficient as they were when brand new.

How Much Does a 5kW Solar System Cost?

A 5kW solar system is only a good option in 2021 if there isn’t enough roof space to install a larger panel, or if you don’t currently need that much electricity and don’t plan on increasing your electricity needs in the future.

It’s not ‘upselling’ when solar panel companies are asking you to consider a bigger system. A 5kW house solar panel cost $10,000 a few years ago. Now, the same amount could get you a 10kW system – a 5kW solar panel in 2021 only costs $3,500 to $7,000.

Prices for solar panels will continue to trend down in the coming years. This will continue even after 2030, once solar rebates will stop and the government ceases to issue STCs.

The longer you put off installing a solar panel, the less of a discount you’re going to get from the government for the installation. Of course, there’s no saying how much the prices will decrease in the coming years, but you can start using the cleanest form of energy available as early as now!

How Much Should I Expect to Pay for Solar Panels in Brisbane?

On the low end, a 6.6kW solar panel system in Brisbane can cost you $5,000. On the high end, you’re looking at spending up to $10,000. More expensive panels are generally much more efficient and reliable than their cheaper counterparts. Below is the average range of prices that you can expect to pay, depending on the output capacity of your solar panel system:

System Size Cost
3 kW $3,800 – $4,800
5 kW $4,200 – $7,200
6.6 kW $5,000 – $10,000
7 kW $5,500 – $10,500
10 kW $7,900 – $12,900

It’s recommended that you speak with a professional solar consultant before installing solar panels on your home. You’re going to be spending thousands on solar devices in the hopes that they’d help you save thousands more in the long run. You don’t want to get ripped off by super-cheap solar panels that won’t do the job.

You may also want to make sure that you’re working with professional installers who can offer warranties and insurances, honor government rebates, and maybe even provide flexibility in terms of payment plans. Professional solar companies offer suggestions and provide optimal solutions for your needs.

There are so many factors at play when it comes to installing solar panels! The great thing about this industry is that it isn’t like other industries… where marketing or company/brand names have more effect on costs than actual utility. As long as you’re working with a reputable solar installation company, ‘getting what you pay for’ is the norm in solar installations.

Are There Any Additional Expenses to Running on Solar Power?

Solar panel systems may require one or two cleanings every year. Accumulation of dust, dirt, and debris on the surface of your solar panels may decrease their efficiency. Thankfully, rain helps to clean solar panels naturally.

Solar panel cleaners may charge a fixed rate per cleaning or charge per number of panels. Fixed rates are usually in the range of $100 to $300. Per-panel rates are usually around $3 to $10 per panel. Check-ups and tune-ups may cost you $150. Solar panel replacements and repair costs vary.
