Commercial Solar Testimonials
What’s the typical payback period for commercial solar?
Most commercial systems pay back in 3–5 years, depending on energy usage, tariffs, and system size. Larger daytime loads often achieve even faster returns.
For an accurate payback forecast, request your free commercial solar assessment.
What financial incentives or tax benefits are available for commercial projects?
Commercial solar may qualify for incentives such as STCs, LGC’s, VEEC’s, depreciation benefits, federal and state based rebates when available. TSP Energy will source every applicable incentive and handle the full process for you.

Is a solar PPA better than buying the system outright?
A PPA suits businesses wanting $0 upfront cost, predictable long-term energy rates, and operational savings immediately.
Owning the system outright generally offers higher long-term ROI, but requires capital.
We can model both options, request your free quote to compare side-by-side.

| What Can you Expect? | Clients can extend, purchase, or have the system removed |
How much roof space do we need for a commercial solar system?
As a guide, 100kW requires around 500–600m².
Actual space depends on panel efficiency, layout, shading, government guidelines and setbacks.

What if our roof is old or needs repairs?
Solar should not be installed on roofs nearing end of life. If repairs are needed, we’ll advise upfront and coordinate work so your investment is protected.
Can you install solar on multiple buildings across our site?
Yes, absolutely.
We regularly design multi-building and multi-meter commercial solar systems, contact us to discuss further.
What warranties come with the panels, inverters, and installation?
Panels typically carry 25–30 year performance warranties, inverters 10–12 years, and we provide a full workmanship warranty on installation.
Do you monitor the system after installation?
Yes. We provide 24/7 remote monitoring, performance alerts, and ongoing support to ensure the system operates as expected.
How do you size a commercial solar system for our energy profile?
We use your interval data, load profile, operating hours, tariffs, and site constraints to design a system that maximises savings and minimises payback.
Can we add more panels or batteries later?
Yes. We design with future expansion in mind, allowing for scalable capacity, additional arrays, or battery upgrades as your load grows.
What makes TSP Energy different from other commercial solar providers?
TSP Energy delivers engineering-led commercial solutions, backed by 15 years of experience, regional Australian values, quality workmanship, end-to-end project delivery, full lifecycle solar services with servicing & monitoring, and end of life solar panel recycling, plus transparent communication and integrity in everything we do. We design, install, monitor, and maintain everything in-house to ensure long-term performance and reliability. Our government track record of delivering multi-site, large, complex and construction related works to enable the solar solution, shows our track record of quality, trust and reliability.

Can solar reduce our demand charges as well as our energy usage?
Yes. A correctly engineered system can lower peak demand by reducing grid draw during high-load periods. Batteries can enhance this further.
We can analyse your interval data to confirm the potential demand charge savings.
Do batteries improve ROI for commercial solar?
Batteries improve ROI when your site faces high demand charges, poor time-of-use tariffs, or outage risk. They also support EV charging and load shifting.
We’ll model the ROI with and without batteries so you can make an informed decision.
Can you model savings based on our interval data?
Yes. Using your 30-minute interval data, we create an accurate savings and payback model tailored to your load profile.

How much can our business actually expect to save each year?
Most commercial clients save 20%–60% on annual electricity costs depending on load shape and system scale.
We can calculate exact annual savings for your site—request your free quote.
How do I know if my roof is suitable for commercial solar?
We assess your roof’s structure, orientation, shading, access, and available space using satellite tools and an onsite inspection if needed.
Get a free quote and we’ll run a full suitability assessment.
Does our building require a structural engineering assessment?
Yes. For commercial systems, a structural engineering report is required to confirm loading capacity and compliance. We organise and manage this for you.
Can commercial solar operate during a power outage?
Standard solar systems shut down for safety during outages.
With a battery and suitable inverter configuration, we can enable backup or partial site operation.
How do you ensure compliance with Australian Standards and grid requirements?
We handle all engineering, design, safety documentation, and commissioning in line with CEC, DNSP, and Australian Standard requirements for commercial systems.
Do we need council approval or any permits?
Most rooftop systems don’t require council approval, but ground mounts, carports, and large-scale works may. We manage all required permits on your behalf.
Can solar power our EV chargers?
Yes. We design systems so onsite solar and/or batteries supply your chargers during the day, with smart controls to prioritise solar, manage loads, and avoid demand spikes.
Want a site-specific plan? Get a free quote and we’ll model charger loads vs solar/battery output.
Is a microgrid suitable for our site or operations?
If you have multiple buildings, critical loads, weak grid supply, or outage risk, a microgrid (solar + batteries + controls, optionally generators) can improve resilience and reduce costs.
Ask for a free assessment and we’ll tell you if a microgrid is justified for your site.
Can you work around our operational hours with minimal disruption?
Yes. We schedule installation around your operational hours, safety requirements, and access needs to ensure minimal impact to your business.
Request a free quote and we’ll plan a delivery approach tailored to your site.
