Off-Grid Solar Systems

An off-grid solar system powers your property without any connection to the electricity network. Solar panels charge a battery bank during the day, an inverter-charger supplies your home or shed, and a backup generator can top up the batteries during long stretches of poor weather. You generate, store and use all of your own power.

It depends on how much power you use, how many days of storage you want and whether you need backup generation. A small shack or cabin system costs far less than a full family home running air conditioning and pumps. We size every system from your actual loads and give you a fixed, itemised quote after a free assessment.

For many rural and remote properties, yes. Running new poles and lines to a block can be very expensive, and once connected you still pay supply charges and usage rates forever. An off-grid system is a one-off investment with no ongoing electricity bills. For properties that already have a grid connection nearby, a grid-connected solar and battery system is usually better value, and we will tell you honestly which suits you.

We design your battery bank to cover a set number of days of autonomy, and we size the solar array for the shortest winter days in your area, not the summer average. For extended cloudy periods a backup generator can start automatically to recharge the batteries, so you are never left without power.

Off-grid solar systems installed by accredited installers can still be eligible for small-scale technology certificates (STCs) under the federal Small-scale Renewable Energy Scheme, which reduces the upfront cost. Other programs vary by state and change over time, so we will confirm what applies to your property at the time of quoting.

Modern lithium batteries typically carry warranties of around 10 years, depending on brand and how the system is used. Correct sizing matters most: a battery bank that is not regularly drained too deep will last longer, which is exactly what we design for.

Yes. We design with expansion in mind, so extra panels or battery capacity can be added as your needs grow, such as a new shed, a pool pump or an extra dwelling on the property.
