Are Solar Panels Worth it? 

Installing a solar system is a smart way to significantly reduce your energy bills while also doing your part for the planet. Once installed, solar systems require minimal maintenance and can even increase the value and appeal of your property.

How Does Solar Work?

Solar power systems work by converting sunlight into electricity using photovoltaic (PV) panels. The panels produce direct current (DC) electricity, which is then converted into alternating current (AC) by an inverter—making it compatible with your home’s electrical system. You can use the power right away, send excess energy back to the grid, or store it in a battery for later use.

Which Solar Panels Are The Best?

With so many solar panel brands and technologies available today—like N-Type, Bifacial, ABC, and more—it can be tricky to know which is the best fit for your property. The truth is, the ideal choice often depends on your specific installation scenario and location. That’s why arranging a pre-site visit with an industry professional is a smart move. They can assess your property, understand your energy needs, and help recommend the perfect solar solution tailored just for you.

How large a system does my business need?

That depends on your electricity consumption, roof or ground space, and your financial goals. A 30kW system is common for small-to-medium businesses, while larger operations may need 100kW or more. We'll size the system correctly during our energy audit.

What's the ROI on commercial solar in NSW?

Commercial solar typically delivers a payback period of 3–6 years for businesses with high daytime energy use. After that, the energy savings go directly to your bottom line for the remaining 20+ years of the system's life.

How much do Solar and batteries cost?

Solar systems can start from around $5,000, but the total cost can increase depending on factors like the size of the system, the complexity of the installation, and whether you choose to include battery storage or other upgrades. Every home is different, so it's best to get a tailored quote based on your property and energy needs.

Can we install solar on a leased commercial premises?

Yes, in many cases. It typically requires landlord consent, but we can help you navigate that conversation with the relevant technical documentation. We've assisted tenants with installations before.

What incentives can I take advantage of?

Starting July 1, 2025, the federal Cheaper Home Batteries Program offers Australian homeowners a rebate of about $330 per usable kilowatt-hour of battery capacity—for example, a 10 kWh battery could receive around $3,300—helping reduce upfront costs by roughly 30%. This rebate applies to battery systems between 5 and 50 kWh, with amounts decreasing annually until the program ends in 2030. Additionally, homeowners can benefit from Small-scale Technology Certificates (STCs), which effectively reduce the cost of solar panel installations by covering up to a third of the system price, making solar and battery setups more affordable overall.

How much will I save installing solar and battery?

How much you save with solar panels and batteries depends on things like how much electricity you use, the size of your system, and where you live. On average, solar panels can reduce your electricity bills anywhere from 30% up to 70% if you produce and use most of your own power. Adding a battery helps you use more of your solar energy by storing excess power for night-time or peak times, boosting your savings even more. Batteries can also provide backup power during outages.

Do we need to notify our energy retailer?

Yes — any system over a certain size requires grid connection approval. We handle all the network applications and retailer notifications on your behalf.

Are there tax benefits for commercial solar in Australia?

Yes. Businesses may be eligible to claim solar system costs under the small business energy incentive or as an immediate deduction under instant asset write-off provisions. We recommend speaking to your accountant about the current year's applicable benefits.
