2. How much does a commercial solar system cost?

The cost depends on the system, design, and equipment quality. At Cyanergy, systems are tailored based on estimates
from the site audit and other criteria. It’s not “one-size-fits-all”.

Typical price ranges in general we see are:

30 kW commercial system: $25,000 – $40,000
50 kW sized system: $45,000 – $70,000
100 kW system: $90,000 – $150,000

3. What rebates or incentives are available for commercial solar?

Businesses and any C&I
properties in Australia can take advantage of generous solar financial incentives that began on October 1,
2025.

Besides that, at Cyanergy, we assist our customers with all major schemes, including:

STCs (Small-scale Technology Certificates)

This rebate applies to systems up to 100 kW. The discount often saves commercial clients $10,000 to $40,000 off the
solar installation price.

LGCs (Large-scale Generation Certificates)

LGCs apply only to systems above 100 kW. These provide ongoing financial returns for the clean electricity you
generate.

Depending on your industry and location, extra funding and
other incentives may be available. Cyanergy’s team stays updated to ensure you never miss a rebate you’re
eligible for.

We handle all the paperwork, from start to finish, so you get the maximum savings with zero hassle.

4. How long is the payback period?

The typical payback period for Cyanergy commercial clients is 2–5 years. However, it depends on:

Energy consumption pattern
Electricity rates
System size
Solar design & orientation
Your operating hours
Shading & roof structure

Businesses with high daytime usage, for example, manufacturing
facilities, warehouses, retail, aged care, schools, etc, often recover their investment even faster.

And the best part? After payback, your system produces free power for 20+ years, which is a substantial competitive
advantage.

5. Can my roof support commercial solar panels?

In Australia, rooftop solar is a very common sight. Most commercial and residential buildings already have solar systems installed, and the number continues to grow rapidly each year.

In many cases, roofs can support solar panels, but an assessment is always essential for commercial setups.

What to look for? Here’s your checklist:

Roof age and condition
Structural integrity
Roofing material type
Weight load capability
Angle, orientation, and shading
Complexity for installation and maintenance

However, if your roof isn’t suitable for mounting solar panels, there are alternatives, such as ground-mounted solar, solar carports, and tilt-frame designs for flat roofs.

You can also use solar paints or window facades to generate solar power.

6. What’s the lifespan of a commercial solar system?

A high-quality commercial solar panel system installed by accredited professionals can last for 25 to 30 years or more.

Cyanergy uses equipment from reputable manufacturers with bankable warranties. We design systems to last well beyond the payback period, ensuring strong long-term ROI

7. Do commercial solar panels require regular maintenance?

Even though solar is low-maintenance, it is not maintenance-free. To make your system function efficiently, you might need to

Perform an Annual inspection.
Cleaning every 6–12 months, depending on dust and debris.
Monitoring system performance through the provided platform.

Remember, this r outine maintenance helps prevent downtime, keeps panels efficient, protects your warranty, and lets you catch issues earlier.

8. Will solar affect my business operations during installation?

Based on our previous installation experience, disruptions are minimal or nonexistent in most cases. The reason is that Cyanergy schedules installations:

Outside peak business hours whenever possible.
For larger systems, we install the panels in stages.
With safety barriers that allow your operations to continue safely and smoothly.

Most commercial clients continue business as usual. We always keep communication clear so you know what’s happening.

9. What brands does Cyanergy use? Are they reliable?

Cyanergy only works with Tier-1 solar panel manufacturers and top-performing inverter brands that are trusted globally.

We choose equipment based on performance, warranty, availability, and your budget. Reliability and lifespan are our top priorities.

Our most used solar panels and inverters are:

10. How much energy will my business actually save?

After installing a solar panel, actual savings can range from 40 to 80% on electricity bills. However, the exact amount depends on:

When your business consumes power
Solar system size
Local weather conditions
Electricity tariffs
Whether battery storage is added for nighttime use

11. What if my energy usage increases in the future?

Expanding a system is not a problem for Cyanergy. The reason is that we always design systems with scalability in mind. We believe that as your businesses grow, your solar system should grow with you!

However, for the expansion, the options include extra roof space for the future, inverter oversizing, Upgradable circuit capacity, and an integrated battery-ready design.

12. Can I add batteries to a commercial solar system?

Yes, and it’s becoming increasingly popular not only in Australia but also worldwide.

Commercial batteries help to reduce peak demand charges, store excess solar for nighttime usage, improve power quality and provide backup protection during grid outages.

Cyanergy supplies commercial-grade battery solutions for business sizes ranging from small offices to large industrial facilities.

13. What if my business moves? Can I take the solar system with me?

Even though the answer is technically yes, practically, it depends!

Removing and reinstalling a large commercial solar system can be costly in most cases. Therefore, many businesses choose to leave the system and increase the property’s value or install a new, tailored system at the new site.

If you are still perplexed about what to do, Cyanergy helps you evaluate the ROI of both options before making a decision.

20th Century Austrian-American economist and devout anti-communist Ludwig von Mises clearly believed what he said at left, and there were plenty of examples in the 1900s to support his concept.

Now, 50 years after his death, we wonder what he would think about today’s United States.

The U.S. has an economy that’s as close to unadulterated capitalism as anyone could imagine, but we have a president who is most definitely an authoritarian, a would-be dictator.
