From July 1, 2025, the Australian Government’s Cheaper Batteries for Homes program offers a rebate of up to $370 per usable kilowatt-hour (kWh), potentially saving you around $3,000 on a typical home battery installation. To qualify the system must be between 5kwh and 50kWh in capacity, be installed by a CEC accredited installer, be Virtual Power Plant (VPP) ready and be installed on a home or business with new or existing solar.

The amount you save depends on your energy usage, location, and the size of the system. On average, customers can reduce their electricity bills by up to 70%, with further savings by storing excess energy in a battery for later use.

Solar panels typically last 25-30 years, with minimal maintenance required. Modern batteries generally have a lifespan of 10-15 years, depending on usage and quality. Both are excellent long-term investments in energy efficiency.

Yes, it’s possible to run fully off solar with the right-sized system and battery storage. Most people choose a hybrid setup, using solar power during the day and stored battery power or grid electricity at night, to ensure consistent energy availability.

After an initial assessment of your energy needs, we design a system tailored to your property. The installation process can vary from 1-3 days to 4-6 weeks, depending on the size of the system. We handle everything from connect applications, engineering to the final commission and handover.

A solar battery functions as a storage system for the electricity produced by solar panels. When sunlight shines on the solar panels installed on your roof, they harness the sun's energy and convert it into usable electricity. This electricity is primarily used to power your home or business, but there are instances when the solar panels generate more electricity than your immediate needs. Rather than letting this surplus energy go to waste, a solar battery comes into play by storing the excess electricity for future use. It is like having a container of stored power that you can tap into during times when solar production is insufficient, such as at night or on rainy days. This way, you can make the most of the energy your solar panels generate and maximise your reliance on clean, renewable solar power.

At One Au Energy, we understand the growing demand for EV charging infrastructure in commercial environments, and we are well-equipped to meet those needs. Whether you have a small business, a corporate office, a retail establishment, or any other commercial property, we can design and install EV charging solutions tailored to your specific requirements. Our experienced team of electricians has extensive knowledge in commercial electrical installations and can handle projects of various scales. We offer a range of EV charging solutions suitable for commercial and workplace settings, including both AC chargers and DC fast chargers. We can help you select the most appropriate charging equipment based on factors such as expected usage, available power supply, and the needs of your employees, customers, or visitors.
Even though solar panels are very adaptable to a range of harsh conditions; we still do recommend at least once a year clean. This can be done via a wipe over with a clean cloth, or you can utilise the services of a solar maintenance company that will run performance tests as well as a general clean. If your home or business is exposed to more environmental conditions, then a 6 month maintenance routine might be more suitable.
