Commercial Solar & Battery Solutions – PSEnergy

Commercial solar isn’t just about sustainability — it’s a smart financial move. Electricity prices in Melbourne continue to rise, and a correctly designed solar system can cut your daytime power costs significantly. With government incentives and the right system design, solar becomes one of the most cost-effective upgrades your business can make.

With the correct design and integration of VEECs (Victorian Energy Efficiency Certificates), many of our clients are seeing ROI in as little as 3 years. This depends on your site’s load profile, operating hours, and system size — but in most commercial applications, the system pays for itself long before its warranty period ends.

Between energy bill savings, government rebates, and VEEC incentives, most commercial solar systems we design pay for themselves in 3–5 years. If you include batteries for peak demand shaving, this ROI can be extended slightly, but the long-term gains are substantial.

Batteries help businesses manage energy use more intelligently. They can:

  • Reduce peak demand charges
  • Provide backup power
  • Maximise solar self-consumption

For businesses operating outside daylight hours, batteries offer control and resilience — with the right setup, it can significantly reduce grid reliance.

Yes — when integrated with backup functionality, batteries provide seamless switchover during outages. For businesses that rely on consistent power — manufacturing, data, cold storage — this protection can be invaluable.

Yes. Commercial systems may be eligible for:

  • VEECs (Victorian Energy Efficiency Certificates) — a Victorian state-based rebate that can dramatically reduce system costs.
  • STCs (Small-scale Technology Certificates) — for systems up to 100kW.
  • Accelerated depreciation under the ATO’s instant asset write-off.

PSEnergy is experienced in structuring designs to maximise eligibility and value from these schemes.

We begin with a detailed site analysis, including consumption profile, roof orientation, and load pattern. From there, we custom-design a system that maximises financial and environmental return. As licensed electrical inspectors with years in renewables, our designs are accurate, compliant, and tailored for results — not just aesthetics.

Our team evaluates:

  • Existing infrastructure (main switchboard capacity, cable paths)
  • Structural roof integrity
  • Sun exposure and shading
  • Consumption patterns from your interval data
  • Export limitations or grid constraints This informs a design that ensures performance and longevity.

Absolutely. We manage all applications with your DNSP (Distribution Network Service Provider), structural and electrical compliance, and ensure grid approvals are fast-tracked.

System sizing is based on your usage profile, load consistency, roof space, and future business growth. Oversizing your solar array relative to your inverter can maximise your yield across seasons — which leads us to the next question…

This is intentional. Oversizing the array ensures you generate more during lower light periods, like winter or overcast days. It also helps the inverter stay in its optimal efficiency range for longer, ultimately improving your total generation without overcapitalising.

We’re not a volume-driven operation. At PSEnergy, you deal directly with experienced professionals — including a licensed Victorian electrical inspector with deep knowledge of the renewables sector. Our bespoke designs, timely delivery, and genuine care set us apart. We don’t send sales reps. We send experts.

We only specify top-tier, CEC-approved equipment — but our focus is not on brand name marketing. It’s on performance, longevity, and warranty support. We’ll guide you to the right product based on your goals and budget.

Yes. All our systems include live monitoring dashboards with performance tracking, alerts, and reporting tools. You’ll always know your savings, output, and system health — and we keep an eye on it too.

We offer scheduled and on-demand maintenance plans. As a licensed inspector, we also conduct performance audits, thermographic inspections, and safety reviews for new or existing systems.

Prices vary depending on size, accessibility, and energy requirements. As a guide:

  • Small commercial (30kW) can start from ~$25k–$35k
  • Larger systems (100kW+) may range from $80k–$150k+ These figures are before VEECs, STCs, and other subsidies. We provide transparent proposals with full ROI projections.

Yes. We can connect you with solar-specific finance brokers who offer options like:

  • Power Purchase Agreements (PPA)
  • Chattel Mortgage
  • Operating Lease These allow you to preserve capital while still enjoying savings.

Yes. Solar is eligible for instant asset write-offs and depreciation under ATO guidelines. We recommend speaking with your accountant to structure this in the most tax-effective way.

A hybrid system includes both solar panels and batteries, connected to the grid. It allows businesses to use solar when available, store excess, and draw from the grid only when needed — ideal for 24/7 operations or those seeking more energy independence.

Battery life depends on usage patterns and technology, but most commercial-grade batteries have a warranty period of 10–15 years and a useful lifespan of 12–18 years with proper management.

Solar alone typically delivers a faster ROI (3–5 years). Batteries can extend this to 6–10 years — however, when used for peak demand shaving or resilience, their strategic value often outweighs the extended payback period. They are increasingly viable in Melbourne’s rising energy market.

Solar can still benefit you:

  • Some landlords offer rent incentives for solar installation.
  • Energy savings often outweigh lease costs.
  • Solar can be relocated or structured under a Power Purchase Agreement (PPA) that doesn’t require ownership. Talk to us — we’ve designed solutions for tenants before.

Absolutely. A poor design can underperform by 20% or more. Proper design ensures:

  • Panels are correctly angled
  • Inverters are matched
  • Your load profile is considered We specialise in precision — both electrically and structurally.

Without structural certification, your system risks non-compliance and insurance issues. More importantly, it’s a safety issue. We work with qualified structural engineers to ensure your roof can safely carry the load — especially in Melbourne’s variable weather conditions.

That depends on your roof pitch, orientation, and available space. Tilt frames improve solar harvest on flat roofs but can increase wind loading and installation cost. We assess this during design to ensure maximum yield for minimal extra outlay.

This is known as virtual net metering or multi-site solar sharing, and while not yet fully supported on all networks, it’s a growing area. Some corporate groups use embedded networks or behind-the-meter solutions to spread value. Let’s assess your setup and explore the options.

Yes — monitoring is crucial. It ensures your system is working as expected, allows you to detect faults early, and helps with accurate reporting. All PSEnergy systems include user-friendly monitoring platforms — and we can remotely monitor it for you as well.
