Frequently Asked Questions
What is an off-grid solar system, and how does it work?
An off-grid solar system is a standalone power system that operates independently from the electricity grid. It typically includes solar panels, battery storage and an inverter, allowing your property to generate and store its own electricity. Some systems may also include a backup generator for additional reliability.
Can a solar system really power an entire farm, home or business?
Yes. Solar systems can be designed to power homes, sheds, irrigation pumps, cold rooms, machinery and other farm infrastructure. The system size is customised based on how much electricity your property uses each day.
How much does an off-grid solar system cost in Australia?
The cost depends on your energy usage and the size of the battery system required. Smaller systems may cost less, while larger residential, farm or commercial off-grid systems can range from around $30,000 to $150,000 or more depending on system size and complexity.
What type of batteries are used in off-grid systems?
Most modern off-grid solar systems use lithium-ion batteries because they are more efficient, longer lasting and require less maintenance than older battery technologies. These batteries typically last between 10 and 15 years depending on usage.
What happens at night or during cloudy weather?
Solar panels generate electricity during the day, and any excess energy can be stored in your battery system. This stored energy can then power your home, farm or business at night or during periods of low sunlight.
Can I add a battery to my existing solar system?
Yes. In many cases, a battery can be added to an existing solar system to allow you to store excess solar energy generated during the day. This helps increase your energy independence and reduces the amount of electricity you need to buy from the grid.
Can solar systems be installed on rural properties and farms?
Yes. Solar and battery systems are commonly installed on rural properties to power homes, sheds, irrigation systems, pumps and other farm equipment. They can also help reduce reliance on generators or long grid connections.
How do I know what size solar system I need?
The right system size depends on how much electricity your property uses each day. Your solar installer will usually review your electricity bills and energy usage to design a system that suits your property and future energy needs.
