Yes. Solar is the most effective way to insulate your home or business from rising energy costs. By generating your own power, you reduce the amount of electricity you need to buy from the grid. Most customers reduce their electricity bills by 70–80% by shifting their usage to daylight hours or adding a battery to power their home at night.
Not necessarily. While North is traditionally best for peak mid-day production, systems can be installed facing anywhere from East to West. In fact, many modern systems are designed with panels on the East and West to catch the morning and afternoon sun, which often matches the electricity usage habits of working families better than a North-only system. Our designers will tailor the layout to match your specific energy consumption.
You can, but a "cheap" system often comes with significant trade-offs. In the solar industry, lowest-price components often suffer from micro-cracking, delamination, and inverter failure within the first 3–4 years. This means the system often breaks before it has paid for itself. At One Power, we use premium components designed to outlast their warranty periods. We focus on the long game—ensuring your system saves you money for decades, not just a few years.
The Federal Government’s Small-scale Technology Certificate (STC) scheme acts as a point-of-sale discount. The value depends on your location and the date of installation. As of 2026, the rebate for a standard residential system (e.g., 6.6kW) typically reduces the upfront cost by approximately $1,600 to $2,000. Please note that the federal rebate reduces slightly every year on January 1st until it phases out in 2030. At One Power, we handle all the paperwork and deduct this rebate directly from your quote, so you only pay the "out of pocket" price.
Aside from the STC rebate mentioned above, some state governments offer interest-free loans or specific battery subsidies. These offers change frequently. Our solar advisors are up-to-date on all current Australian state and federal incentives and will help ensure you claim every dollar you may be eligible for.
For many homes, yes. With feed-in tariffs (the rate you get for selling power to the grid) now quite low across Australia, the smartest way to save money is to store your solar energy to use at night. A battery allows you to keep your lights on during blackouts and use your own free power in the evening, rather than buying it from the grid at peak rates.
Yes. Charging your EV with solar power is essentially "charging for free." We can design your system with sufficient capacity to cover your home energy needs and your daily driving, maximising your return on investment.
A VPP is a network of home batteries connected via smart technology. If you install a battery with One Power, you may be eligible to join a VPP program. This allows you to earn extra credits or cash payments for supporting the grid during peak demand times, further reducing your payback period.
The Tesla Powerwall 3 is an industry-leading all-in-one solar and battery system. It features an integrated solar inverter, high efficiency, and a durable design. It allows you to store excess solar energy for use at night or during outages. One Power is a certified installer of the Powerwall 3.
Yes. All One Power systems are "battery ready." However, installing the battery at the same time as the panels often saves on installation costs and allows you to start maximizing your savings immediately.
We aim to make it seamless and fast.
When you’re ready to go solar, a solar advisor can provide you with an installation proposal. This proposal will be based on factors such as your recent power bills and property location, and will evaluate both your power and lifestyle needs so we can give you accurate pricing information. If you decide to go ahead, we can schedule an installation and complete everything, including cleaning up after ourselves, within as little as one day. From there, we’ll provide you with maintenance guides and dedicated after-sales support whenever you need it.
