Commercial Solar Panel Costs: What to Expect

These days, with all the state-sponsored solar feed-in tariffs, closed to new applicants, the answer depends mainly on the amount of energy that you use during daylight hours and how you use it. Unless you are planning on installing battery storage as well, new solar systems should be sized to meet your daytime electricity needs. Any excess solar will essentially be ‘wasted’ – currently, Queensland retailers offer only up to 8-12c/kWh for your extra solar energy, significantly lower than standard retail electricity rates. Commercial and industrial solar panels offer a powerful solution to rising electricity costs, power instability, and environmental concerns. Whether you run a factory, a mall, a school, or a hospital, switching to solar can give your business long-term financial and environmental benefits. In recent years, solar energy has transformed from a futuristic concept into a practical solution for businesses across the globe.
Our team of Clean Energy Council (CEC) accredited designers and installers brings precision, transparency, and experience to every project. Whether you’re running a warehouse in Brisbane or a retail space on the Gold Coast, choosing the right system and partner is key to maximising ROI. Tasmania’s Energy commerical solar system price queensland Saver Loan Scheme offers interest-free loans of up to $10,000 to assist households, landlords, small businesses, and not-for-profit organisations adopt energy-efficient products. Eligible items include PV systems, solar battery storage systems, reverse cycle air conditioning, hot water systems, induction and ceramic stove tops, energy-efficient white goods, double glazing, and insulation.

REA Solar recommends Tier 1 panels that suit Queensland’s climate and high UV exposure. For a more precise idea of the financial benefits of solar power for your business, it’s always wise to get quotes from reputable solar installers. You can use resources like Energy Matters‘ free solar quote service to get quotes from pre-vetted solar retailers in your area and compare plans to find the best fit for your commercial solar system needs.
To qualify for this cheaper and faster process the commercial solar system must not exceed 30kVA in inverter capacity. That means you can oversize the Solar Panels up to 39.9kW in capacity while still using a 30kVA inverter. A qualified installer can complete this application process on your behalf. Not only are Canadian Solar panels of great quality, but they also come at an extremely competitive price.
Often for single phase connections the limit is a 5kVA inverter which can accommodate 6.6kW of solar panels. Because of the complexity involved (not to mention the cost), we recommend  that you have the numbers crunched in detail before deciding to go ahead with a 15kW solar system. We help you understand what the data means and identify any issues before they cost you money. The best commercial PV panels Australia offers not just durability and efficiency but compatibility with modern tech platforms. That’s why our solutions at REA Solar are future-proofed, allowing you to scale or upgrade as your business grows.

However, like most commercial products and applications, everything is done on a larger scale than those for residences. Commercial panels will likely be larger/have more wattage than residential solar panels. To become a solar  installer in Australia, you need to complete a Certificate III in Electrotechnology Electrician and obtain a state-recognised electrical licence.
To help with the cost, the Australian Government announced a $2.3B initiative (April 2025), slashing battery prices by up to 30% and supporting over 1 million battery installations nationwide. It's never been a better time to prepare for the future — and keep your solar working harder, for longer. Commercial and industrial solar panels are photovoltaic (PV) systems designed specifically for non-residential use. Our residential solar systems are designed for maximum output and long-term reliability.

Always go for an accredited solar installer when installing your solar panels. Once your 100kW commercial solar system is running, installing a solar battery can drastically improve the system’s ROI.  The battery allows you to store the free solar energy for later use instead of relying on power from the grid and the feed-in tariffs.

The Australian government runs an incentive program that allows solar owners to receive up-front discounts on their solar systems. This is part of their Small-scale Renewable Energy Scheme that aims at encouraging more Australians to adopt renewable energy sources. Yes, businesses can access Small-Scale Technology Certificates (STCs) for systems under 100kW and Large-Scale Generation Certificates (LGCs) for systems over 100kW. Additional state-based grants and incentives  may also be available to lower installation costs. Currently, we are using Tier 1 Jolywood N-Type solar panels when installing on Commercial properties as they last longer, considered the best bang for buck panel with a 15-year product warranty. This works because in many cases the ROI from solar can be as high as 25-45% and the cost of funding on solar rental or EUA can be as little as under 7%.
A 19.95kW solar system is one of the most popular entry-level commercial systems and a smart energy solution for small to medium businesses.
