Rebate and Finance Options

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.

Benefits of a 30kW Solar 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.

30kW Solar System Installation

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

Customer here from eastern Perth suburbs got installed with 16KW solar, 10kw-3phase inverter and 24kw battery. I am surprised how the solar from the sun really powers our household. However, I will comment that with Solar365 installers, they left all the boxes, rubbish and the old panels which I paid extra to be removed and cleaned. Overall, I am happy with a competitive price and service provided.
