What are commercial solar panels & batteries?
Commercial solar panels convert sunlight into electricity for your premises. A commercial solar battery stores excess solar energy for use in the evening or during peak tariff periods. Together, solar and storage reduce reliance on the grid, stabilise energy costs, and provide cleaner, more reliable power. For large businesses that use a lot of energy, a well-designed commercial solar panel installation can deliver long-term energy savings and operational resilience.

Commercial solar panel prices & total system cost
Your commercial solar panel price depends on system size (e.g., 30 kW, 100 kW, 500 kW+), panel and inverter selection, engineering complexity, metering, and roof or ground-mount works. A comprehensive quote should outline:
System design and equipment
Panels, inverters, racking, and engineering.
Installation and performance
Commissioning, monitoring, and warranties.
Upgrades
Optional commercial solar battery and inverter additions.
We’ll help you secure multiple quotes so you can compare commercial solar panel prices on a like-for-like basis. Our focus is on long-term performance, including lifetime yield, warranty coverage, and payback period, not just the upfront solar panel price.

Who are commercial solar systems best for?
Businesses with steady daytime energy use like manufacturing, warehousing, retail, agriculture, hospitality, health, and office sites, see the strongest returns. If you’ve got suitable roof space or land, stable tenancy or ownership, and rising electricity costs, commercial solar panels and batteries can deliver solid ROI and measurable sustainability gains.
Government incentives (SRES & LRET) and payback
Australian businesses can tap into several solar and battery incentives that reduce upfront costs and improve payback. The SRES and LRET schemes lower the cost of eligible commercial solar panel installations, while Victoria’s VEU and NSW’s PDRS programs add further savings on solar and battery systems.

Initiatives such as the Cheaper Home Batteries Program and the NSW battery rebate can also cut commercial solar battery installation costs. We include every applicable incentive in our feasibility modelling, so you get a clear view of payback periods and ROI before making a decision.

Frequently Asked Questions
How much do solar panels for businesses cost in Australia?

Prices for business solar panels vary based on system size, equipment, and site complexity. We’ll help you secure multiple quotes and model lifetime returns so you can compare commercial solar panel costs on a like-for-like basis, with all the facts, no guesswork.

What size commercial solar system do I need?

System size depends on your interval data, roof space, and energy rates. Our feasibility study sizes your solar panels and any commercial solar battery to maximise savings and strengthen payback.

How long does commercial solar panel installation take?

From approvals to commissioning, typical timelines range from a few weeks for small systems to several months for larger projects, depending on engineering and network approvals.

Do I need a commercial solar battery?

Not always. Batteries add value where demand charges are high, backup is critical, or TOU tariffs suit storage. We’ll help you model the economics of commercial solar batteries for your load.

What incentives are available (SRES/LRET)?

Eligible systems may access the SRES (STCs) or LRET (LGCs), which reduce upfront commercial solar panel costs. In Victoria, the VEU incentive offers extra rebates for solar installations. NSW businesses may benefit from the PDRS (Peak Demand Reduction Scheme), along with battery programs like the Cheaper Home Batteries Program and the NSW battery rebate. We include all applicable incentives in your payback analysis for an accurate view of total savings.

Who installs the system?

We connect you with vetted commercial solar panel installers via Solar Choice and compare proposals for quality, warranty and price before you decide.

What warranties should I look for?

Panel product and performance warranties, inverter warranties, workmanship, and monitoring coverage. We’ll help you assess terms across quotes.

Can commercial solar run at night?

Panels generate by day. With a commercial solar battery, stored energy can be used in the evening or during peak periods.

How will solar affect my electricity contract?

We align your energy procurement and commercial solar installation strategy to optimise tariffs, demand charges and export arrangements.

How do I know if I am classed as a small or large business by my energy consumption, and what energy market should I be in?

The small energy market for SMEs (small and medium-sized enterprises) typically includes businesses consuming under 100,000 kWh of electricity or spending less than about $2,500 monthly on energy. Bills for these customers are usually sent quarterly.

On the other hand, the large energy market for C&I (commercial & industrial) businesses consists of those using over 100,000 kWh per year or spending more than about $2,500 a month. In NSW, VIC, QLD, and ACT, a C&I business is defined as one that consumes more than 100,000 kWh annually. In SA, this threshold is set at over 160,000 kWh per year, with bills always issued monthly.

What sets small business (SME) energy customers apart from large business (C&I) customers is that the large business customers can participate in, or qualify for, the wholesale energy market, enabling them to secure forward purchasing at better rates.

To figure out where you stand, simply check your energy bill. With this information, you should have no trouble determining if you've received a SME or C&I energy bill.

How often should businesses review their energy procurement contracts?

As most commercial energy procurement contracts are locked in for the full term agreed upon, businesses should review their contracts within the 12 months leading up to the end of their current agreement. This strategic timing allows for an assessment of market conditions, exploration of new pricing options, and negotiation of better terms before renewal.

By proactively managing your energy contract with Zembl's Energy Consultants, you can always stay on competitive rates and ensure your energy contract aligns with your business needs.

What are the common mistakes to avoid in commercial energy procurement?

Common mistakes in commercial energy procurement include failing to conduct thorough market research, not understanding contract terms fully, and neglecting to consider the contract term length that would be most beneficial based on market conditions. Another pitfall is delaying decision-making, which can result in missed opportunities for locking in favourable rates.

Working with Zembl's experienced Energy Consultants will help avoid these errors and ensure you're able to navigate the complex commercial energy procurement landscape with ease.

Are there government programs or incentives for commercial energy procurement?

There are no government programs or incentives for businesses directly relating to energy procurement itself, being the process of tendering and negotiating better energy rates in your contract.

There are, however, various government programs and incentives available to support energy efficiency, which in-turn should mean you use less, and ultimately pay less. These may include tax credits, grants, rebates, and subsidies aimed at promoting energy efficiency and the adoption of renewable energy sources. Businesses should explore these opportunities to reduce costs and enhance their sustainability efforts.

Whether you're a Zembl Energy Procurement customer or not, you can avail of our Energy Efficiency service, where we've partnered with trusted local experts who can provide energy efficiency solutions such as solar panels, batteries, LED lighting, heat pumps, Power Factor Correction (PFC), and energy audits. These partners are well informed about any and all available government incentives for these solutions and will be able to guide you through the process if you’re business is eligible.

What should businesses know about energy market trends and their impact on procurement?

Understanding energy market trends is critical for effective procurement. That's why Zembl's Energy Consultants have their finger on the pulse when it comes to wholesale energy prices, regulatory changes, technological advancements, and geopolitical events that can influence the energy market.

By keeping up to date with these trends, they can better predict price movements and make more informed procurement decisions, meaning Zembl customers can always secure competitive rates when renewing their commercial energy contracts.
