Installing a solar system significantly reduces your dependence on the grid. By generating your own electricity, you can lower your monthly energy bills, freeing up more funds for other essentials.
Solar panels are a long-term investment with high returns. Over time, the savings on energy costs can far exceed the initial installation costs, offering substantial financial benefits in the years to come.
Take advantage of government rebates and incentives for solar installation. These financial benefits reduce your upfront costs, making solar energy more affordable and accelerating your return on investment.
Shield yourself from rising energy prices by going solar. With a fixed energy source, you can avoid the uncertainty and fluctuations in energy costs, ensuring long-term savings and stability.
Solar systems can be a bit tech jargon intensive. Whether you intend to purchase a solar system, find out if it’s right for you, just curious about the technology or want to understand a quote you’ve received from a different company, it all starts with booking a quick consultation session with us.
Our CEC design accredited engineering team will quantify your needs and capitalise on maximising your benefits. Once that is achieved, we will share a preliminary design in the form of a proposal.
Our project management team submits a grid connection application to your electricity distributor. Once approved, they will liaise with our CEC accredited installers, and aim to install your solar system within 2-4 weeks.
Guwing Green started as an obsession in renewable energy, evolving into a company that provides real Australian families and businesses the power to utilise state of the art renewable energy technologies and long term sustainable energy solutions.
Our mission is to help everyday Aussies save thousands on their energy bills and beat the rising price of energy in Australia.
The Aluminium standing seam roof needed a special mounting design to avoid any reaction between elements found in the roof sheets and the solar panel rails. A micro-inverter system was used as the site suffered from extensive shading throughout the day.
The multiple orientations of the roof and the nature of the surrounding environment made this project quite challenging. Key design approach was to have the flexibility of increasing system size in the future, as well as connect a battery and EV charger powered by the solar system.
After modelling site consumption, the client needed to add ~ 4.5kWs to their existing system. The tile part of the roof was high pitched, old and had no spare tiles. A cost to benefit analysis was conducted. In order to avoid potential roof leaks and other risks, 5 panels were placed on the extension part […]
This site had one of the steepest roofs we’ve seen with a 50° pitch! After the customer was knocked back by many solar companies, we were able to step up to the challenge and get it done while meeting the highest saftey and quality standards throughout the entire process.

A quick rule of thumb is to multiply your current electricity bill by 0.4 and the answer is your potential savings after installing solar!
E.g. Your bill is $1,000 this quarter. Using the calculation 1000 x 0.4 = 400 meaning you could potentially save you, your family and your business $400 this quarter.
While this is a great tool to get an idea of your potential savings, your actual savings are affected by:
Your electrical load profile. Meaning what you use, when you use it and for how long?
Solar system size and grid export restrictions in your area.
Feed-in Tariffs, which is what your retailer pays you for any excess energy you produce from solar and haven’t used. Different retailers offer different incentives.
Where you live. The more sun you get, the more $$$ you can save.
The cost of a solar system depends on many factors that are assessed on an individual basis.
For example, compare your home to your neighbour’s.
Do they look the same?
If they do, do they have the same orientation?
What about available roof space?
Speaking of roofs, is it tile or tin?
Do you have any trees in your backyard or do they?
How many people live in your household and how many live in your neighbour’s?
Is your consumption during the day and is theirs at night?
As you can see, we have mentioned only a few factors that are taken into consideration when designing a solar system for you. Once our engineers have carefully assessed your home for your new solar system, an accurate proposal is shared for your consideration.
Our solar systems are covered by a 5 year whole of system warranty as per CEC retailer approved guidelines.
You may have seen longer warranty periods however do not confuse a 25-year performance warranty with a 25 year system warranty. Performance warranty is strictly related to solar panels, meaning the panels should perform for 25 years at around 80% efficiency on the last year.
A more realistic system warranty is 5 years. Most panels come with a 10-20 year product warranty, inverters 5-10 and batteries around 5-10 years as well.
If you consider 2030 to be soon, then yes, they are ending soon. Every year, rebates are reduced until the scheme ends in 2030.
For example, if you buy and install a solar system by the end of this year, it will cost you less than what you’d pay for a system installed in the beginning of 2022 all else being equal.
You will still get rebates if you install a solar system next year or the year after that. Take your time, make the right choices and don’t be tricked into a solar system just because someone tells you the scheme is ending because it isn’t.
If a panel is branded as Tier 1, it means that according to Bloomberg New Energy Finance PV Module Tiering System, the manufacturer of this panel has Tier 1 bankability.
Meaning the manufacturer has a stable financial background as well as other criteria that would most likely keep them in the business for a long time.
A Tier 1 brand should not be confused with a measure of quality, performance, and efficiency of a panel albeit they do go hand in hand.
When faced with the need to replace solar panels in an existing system, attention to detail is paramount to ensure compatibility and efficiency. First, assess whether the original solar installer or company is available, as their expertise can guide the selection of appropriate replacements. If not, contacting the manufacturer of the original panels is crucial for acquiring guidance on suitable options, particularly if a well-known brand was used.
For those with older systems or less common brands, finding direct replacements may be challenging. In these cases, consulting with an accredited Clean Energy Council designer becomes essential. They will analyse the system’s wiring, existing panel specifications, and inverter configurations to recommend an alternative panel that seamlessly integrates with the current setup. This expert evaluation helps maintain the system's overall performance and longevity while ensuring compliance with industry standards.
This depends on the quality of your chosen solar panels. High-quality solar panels are crafted from tempered glass, allowing them to withstand hailstones in most cases. Although it is important to note that a large, fast-moving hailstone can damage even the best panels. Therefore, we recommend you to:
The taxation of solar energy payments can vary depending on your location and the specific incentives or rebates you receive. Here's a more concise and structured rewrite of the information:
The Australian Taxation Office (ATO) has addressed the tax treatment of payments received from electricity suppliers for solar power generation:
No specific legislation: Private binding rulings confirm there are no legislative provisions directly addressing these payments, meaning they are not statutory income.
Not ordinary income: The ATO generally does not classify these payments as income according to ordinary concepts for typical homeowners. This is based on:
The scale of equipment used
Current pricing structures
Electricity production for domestic purposes only
Private/domestic nature: The ATO considers these payments to be private or domestic in nature.
Conclusion: Payments received from electricity retailers for solar power exported to the grid are not considered assessable income for typical homeowners, but always best to consult a tax professional.
