Plain English. No jargon dressed up as expertise, no fine print tucked under footers.
If something isn't right on handover, we're back on the roof until it is.
Work Process
From your first phone call to switch-on, our process is deliberate, accredited and typically wrapped within 2 to 4 weeks of grid approval.
01StepBook Consultation
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.
02StepSolution Design
Our SAA 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.
03StepSystem Installation
Our project management team submits a grid connection application to your electricity distributor. Once approved, they will liaise with our SAA accredited installers, and aim to install your solar system within 2-4 weeks.
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.

Selected installs that wouldn't take a template. Each one is engineered around a different roof, brief and budget.
11.1 kW Solar
Bilgola Beach
Copper façade of the house and roof. Custom mounts and a hand-made copper conduit to hide every cable. Panel and micro-inverter selection had to account for the nearby beach.
100 kW Solar
Russell Lea
Carefully designed to meet our client's energy needs and accommodate for ongoing maintenance and futureproofing. The switchboard location was not ideal for inverters or cabling.
7.4 kW Solar
Balgowlah
Multiple roof orientations and surrounding environment made this challenging. Designed to flex up in future, including a battery and EV charger powered by the solar system.
We pick what fits your roof, your loads and your budget — not what the truck happens to be carrying this week.
Solar Systems
Right-sized panels for your roof
Tier-selected for efficiency, temperature coefficient and warranty — not the marketing label.
Battery Storage
Power when the grid isn't there
Tesla Powerwall, Enphase IQ and other batteries — sized to your evening load, not a brochure.
Energy Audits
Meter data before sales pitch
Twelve months of interval data turned into a payback model you can actually read.

“Paul from Guwing Green was great to deal with, had a professional approach and took the time to understand my requirements, explain all the components of the install and its capabilities, and do a thorough on-site visit to plan the installation, cable runs, inverter location etc.”

The questions our inbox gets every week, answered in plain English.
A quick rule of thumb is to multiply your current electricity bill by 0.4. The answer is your potential savings after installing solar. For example, a $1,000 quarterly bill × 0.4 = $400 you could potentially save your family and your business each quarter. Your actual savings are affected by your electrical load profile, system size, grid export restrictions, feed-in tariffs and where you live.
After the federal STC rebate is applied as an up-front discount, most residential systems land between $4,000 and $15,000 depending on size, inverter and any battery. Commercial systems are quoted line-by-line against your meter data.
Yes. Manufacturer warranties cover panels (typically 25 years), inverters (10 to 15 years) and batteries, plus our own workmanship warranty on the install. If something fails, we handle the claim end to end.
The federal STC scheme is stepping down each year and ends in 2030, so the rebate gets smaller every January. It hasn't ended yet, but sooner is better than later if rebate value matters to your payback.
Our team of engineers is here to help and will work with you to design a solar system that meets your energy needs and maximises your financial savings.
