The Howells family in Brisbane’s Forest Lake used 35.86 kilowatts (kW) of power per day on average.

Their old 1.5kW system wasn’t cutting the mustard!

Our solar company upgraded them to a shiny new 10.36kW solar power system that could handle the pool pump and the family’s lifestyle, saving them thousands of dollars per year in power costs.

Now they can enjoy the pool and the Brisbane summer without the bill shock because they switched to a solar power system.


Need more information on how solar power works? Easy. We’ve covered everything you need to know about getting started below.

Ultimately, the more electricity you use daily, the more solar panels, solar inverters, and potential solar batteries you’ll require to power your home adequately. To ensure you invest in the most appropriate system for you, we always recommend speaking to our specialists to understand the space you have to work with, who will custom design a solar system that considers your lifestyle needs.

Luckily, there are four easy ways to work out your solar power needs straight off the bat:

How to find how much electricity you use on average per day.

On your power bill or your energy providers app, you will find the “Average daily usage”, which is how much electricity your home is using per day on average.

Work out how many sunlight hours you get per day.

You can calculate this yourself or by using online tools, or our software will factor this in automatically when your consultant generates your proposal and shows you your savings.

Determine the daily electricity output from a solar power system, using sunlight hours in the equation.

To do this, multiply these hours per day by the solar panel system wattage.

Divide the total electricity output for a solar panel by your overall daily electricity consumption.
Sound like a hassle? 

We understand this process is complicated and technical. Hence, we make it easy for our customers to understand the solar power system they need for their Brisbane property, considering their lifestyle and household needs.

Instead of trying to solve these puzzles on your own, we recommend getting in touch with our friendly customer service team, and we’ll do all of the math for you on the spot. 

If you are looking to install a solar panel system on your home to save money on your electric bill, you are likely wondering how long it will take for the process to pay for itself. You may also be wondering about the impact of financial incentives on the overall cost of your solar power system.

A complex formula can give you your return on investment.

Better yet, please have one of our professionally trained Solar Consultants can work it out for you using our software to provide you with a conservative view of how quickly your solar system will pay for itself.

This calculation will also indicate the net cost of the system with rebates or incentives applied, helping you understand the overall expenses better. Ultimately for most clients switching to solar is cheaper than paying a power bill, which is why everyone is making the switch.

How do I get this information?

The easiest way is to sit down with one of our professionally trained solar consultants who can factor in your power bill, available roof space and how many solar panels they can fit on. The only reason to scale back the size of the system is if you don’t use enough power during the day. A more extensive solar system is always better for homes running pool pumps because you can run your pool pump and even pool heater during the day, saving you thousands every year.

The health of your roof

The first thing you need to do is find out whether your roof is suitable for installing solar panels. The area around your roof also needs to be free from obstructions such as trees or large bushes that might block sunlight from reaching the panels. Trimming trees is always a good idea.

What if I am selling?

Suppose you plan on selling your property soon. In that case, you could benefit from solar because the REIQ says that a quality solar system could improve the homes resale value by 3% and homes with quality solar panel systems sell faster. We have clients who put a solar system on every property they flip because they know from experience that it will sell quicker and for more money than a completing property. 

One of the significant benefits is Greenleaf Carbon™ allows you to transfer those warranties to the new owner, and they can still get access to monitoring and support when they move in.

The shape of your roof

The shape of your roof can be a significant factor in determining if you should invest in solar panels. Certain types of roofs might not have enough space for solar panels, and a solar panel installation company may not be willing to work with your specific roof shape. The roof shape is important because the company will need to mount the panels to receive maximum sunlight throughout the day. If your roof is too small – for example – the cost of installing solar panels may outweigh the benefits.

Wasted space between panels can cause snow build-up issues for clients in colder climates during the winter months. It would also require more work from the installation company, leading to additional costs.

Although roof shape isn’t typically an issue, some companies may refuse to work with certain roofs. Small triangle shaped roofs are difficult to mount solar panels on, and often it is even possible. Decromastic tin tiles will not stand up to a solar installation, while glazed and nailed terracotta have their issues also. Our solar panels Brisbane team will inspect the space and requirements to determine if this is the case. 

Sloping & Shading

Solar panels get mounted on the roof of your home, so the most crucial aspect that you need to consider is their roof slope. The optimum angle depends on where you live and your solar power provider.

Tilt is a crucial component in how much sunlight reaches your solar panels. Each roof is different in orientation and slope, so our team considers all of these factors. For example, it could be shade from other structures or trees in a reserve that causes us to say no, it is not worth getting solar for your home. However, other companies will install anyway, knowing the client won’t benefit. For example, we had a referral from a great client who lived on the top side of the road near a reserve. His home was fine. However, the lady he referred had three quotes from companies ready to install, but she lived at the bottom of the road, and her home was in the shade. She would have been lucky to produce one hour a day off her solar panels in summer. So we advised solar wasn’t for her saving her thousands. Likewise, if it’s tilted too far north, it might not receive enough sunlight to generate sufficient amounts of power for your home.

There are further considerations to make regarding how much shade your panels are receiving throughout the year. For example, trees, buildings, and other structures nearby can affect your solar panel’s output due to shading issues. But, again, a professional can help you optimise these aspects for maximum payoff.

Weight capacity

Older homes and homes with tile roofs are engineered well and can handle the weight, so the additional weight of a solar system is typically not an issue.

However, new home builder Metricon reminds homeowners and solar installers that the client must specify that they are looking to get solar installed to factor in the additional weight when building a new home.

It has become standard practice for some builders to allow only for the tolerances required for the weight of a Colorbond roof, so be careful.

Installing solar panels will mean more weight your roof needs to carry. 

If the weight of these solar panels is significantly more than your roof can handle, you run the risk of it collapsing. Weight is hazardous for various reasons, not to mention it can also be expensive, especially if the contractor is not insured.

Today, new home builders use much smaller “stick frame” timber, and extra reinforcing must be added to homes getting a Colorbond roof if you wish to install a solar power system.

You must engineer your new home accordingly and check with your builder because the roof structure must handle the weight.


Water drainage is essential. When it rains, all of the excess water runs across your roof, into your guttering, and out and away from your actual home. 

When installing solar panels in Brisbane, installers must factor in rain run-off. Because panels installed too close to the guttering mean the rain will flow straight off the solar module, missing the gutter and can cause damage to your grass or garden or even undermine your home over time. 

As technology in this space continues to advance, so do the types of panels available on the market.

The main types of solar panels used in today’s solar power systems include:

1. Monocrystalline

2. Polycrystalline, and

3. Thin Film (Amorphous).

Monocrystalline solar panels comprise a single type of silicon, and the cells are typically black. This type of solar panel is more expensive than polycrystalline panels but is much more efficient and will last longer in hotter conditions due to its ability to produce more energy in both low light conditions and at 46 degrees.

The second most common type of solar panel is the polycrystalline variety. These solar panels are manufactured with multiple different silicon crystals, making them cheaper than monocrystalline panels. Although some manufacturers have a silver tinted polycrystalline panel, these panels are usually bluish.

The final type of solar panel is thin-film amorphous. These types of panels come in many colours and have a textured look. They use less silicon than other technologies and are typically the cheapest option. Unlike monocrystalline and polycrystalline solar panels, thin-film does not use glass to protect the cells.

Solar panels are a long-term investment, but that doesn’t mean they last forever. The expected lifespan of even the best solar panels is typically between 25-30 years (note: not the warranty length). As more and more installations come online, many of the initial panels are now at or near their end of life, making it crucial to upgrade.

It is worth stating that the old quality monocrystalline panels have lasted ten years, whereas the cheap mono or poly panels have been lucky to last 18 months to 5 years.

25% of our current installations include removing a solar system that is no longer working or a dodgy install inherited with the home. It is worth investing a little more for the peace of mind of a quality installation and quality products because you are putting a power plant on your roof.

When you contact us, we will guide you through everything involved to know what you can expect from your solar system and our install team.

However, it’s essential to understand that other factors can also dictate how long solar power systems work for, including:

What causes a solar panel system to deteriorate? 

Four main factors contribute to expected degradation on solar panel systems, all from natural causes: thermal cycling, damp heat, humidity freeze, and ultraviolet (UV) exposure.

The relationship between these factors and the panels’ lives is not simple to predict. However, the most important thing to remember is that a solar installation can last longer than its expected lifetime when given the right level of attention and appropriate conditions, another reason why we support your system over its life.

Here’s a simple way to understand how a solar panel can degrade naturally over time:

Thermal cycling occurs when panels are exposed to extreme temperature changes. It usually happens in regions where there is extreme seasonal variation. 

Damp-heat: When water collects inside solar panel systems at an angle or when the cells are completely submerged in water or another liquid, they might experience degradation due to damp heat. 

Cheap panels will let water in.

Humidity freeze: This damage occurs when panels are covered with ice and exposed to high humidity. Parts of Melbourne can experience these phenomena as an example.

UV exposure: The most common reason solar panels fail in Australia. Almost all materials degrade when exposed to UV radiation over time. So UV is the main reason we find cheap solar panels, just like the companies that sold them haven’t lasted.

Poor quality solar cells crystalise and crack or end up with hot spots causing the panel to burn out or even catch fire.

Because we are locals, we understand Australia and New Zealand get exposed to more extensive than usual amounts of UV radiation and why we only use quality solar panels for Brisbane and Queensland homes, schools and businesses.

Getting the equation right means your quality solar system will be cheaper than paying your power bill in most cases, and once you own it outright, you can enjoy the benefits and even credits for the next 25 to 30 years.
