The federal government and WA state government both provide rebates and incentives that help the public reduce the cost of a solar system. The federal government provides an STC for solar panels, and both the federal and WA state governments provide rebates for solar batteries.
Finance options are also available through financial institutions and government programs. Plenti and Green Loans provide eligible customers with interest-free or low-interest finance, making it easier to install a solar system.
System Type | Solar System Average Price Before Rebate | Solar System Average Price After Rebate |
30kw solar system (no battery) | $28,000 - $30,000 | $20,300 - $23,002 |
30kw solar system + 30kw solar battery | $37,000 - $40,000 | $30,002 - $32,300 |
Note: The 30 kW solar inverter includes solar panels + solar inverter, which cost $20,300-$22,300 after rebate, and a 30 kW solar system with solar panels, inverter, and solar battery costs $30,002-$32,300 after rebate. The actual pricing depends on your choice of brands and current available rebates for your installation time and your location.
The price of a 30 kW solar system varies in every city in Australia because every city has different climate conditions, sunshine hours, and its own eligibility criteria for rebates.
City | Solar System Average Price Before Rebate | Solar System Average Price after Rebate |
Perth, WA | $28,000 - $30,000 | $20,300 - $23,002 |
Adelaide, SA | $28,200 - $30,200 | $20,500 - $22,500 |

Melbourne, VIC | $28,800 - $30,800 | $22,216 - $24,216 |
Note: This is the average price of a 30kW solar system, which includes solar panels and a solar inverter. The price does not include a solar battery. The final cost may vary depending on the solar panel and inverter brands you choose, the complexity of the installation, and whether you add a battery storage system.
Reduce Business Electricity Costs: A 30kW solar system can generate approximately 120-150 kWh of electricity per day, helping businesses significantly reduce their reliance on grid electricity. It is ideal for commercial properties with high daytime energy consumption, such as offices, warehouses, retail stores, farms, and workshops.
Strong Return on Investment: With the Australian Government's available solar incentives and long-term savings on electricity bills, a 30kW solar system can provide an excellent return on investment. The payback period varies depending on your energy usage, electricity rates, and system performance.
Supports Future Business Growth: A 30kW solar system provides the capacity to support increasing electricity demand, including battery storage, electric vehicle (EV) charging, and future business expansion.
Adds Value to Your Commercial Property: Installing a 30kW solar system can improve the value and appeal of your commercial property by reducing operating costs and increasing energy efficiency.
Low Maintenance and Long Lifespan: Commercial solar panels require minimal maintenance. With regular inspections and occasional cleaning, a 30kW solar system can continue producing clean, renewable energy for 25–30 years.
The installation of a 30kW solar system generally takes 4–6 weeks from quotation to final commissioning. This timeframe includes system design, site inspection, grid connection approvals, and all necessary paperwork. Once the required approvals are in place, the on-site installation is typically completed within 2–3 days, depending on the size and complexity of the project. Solar 365 takes care of the entire process, including documentation, approvals, and installation, so your business can switch to solar with minimal disruption.
The installation process includes:
Custom 10kW solar system design
Roof mounting and solar panel installation
Solar inverter installation
Electrical wiring and safety testing
Grid connection and system commissioning
Monitoring app setup for real-time system performance tracking

Yes, the export limit of extra generated solar power depends on your electricity retailer. Your installer will confirm the approved export limit before installation.
If your electricity demand increases after installing a solar system, your solar installer will assess whether your existing system can be upgraded or whether an additional solar system is a better option.
At present, most solar systems come with smart monitoring apps that let you track energy production, system performance, and any fault notifications in real time.
Yes, you can install a 30 kW solar system across multiple roof sections, provided the roof has sufficient space and receives good sunlight. A professional and experienced installer designs the system according to the customer’s available roof space and location.
