Off Grid Solar Systems

Independence in Power Generation

Our goal is to provide reliable and accessible solutions for Australians homes and businesses who aspire to achieve an “off the grid” lifestyle with continuous innovation and improvement of our stand-alone solar systems. There used to be many constraints to live or operate businesses in off grid setting, however with the technology advancement, this is no longer an issue. You can have a comfortable life and running modern appliances or even machinery for your factory without any issue.

Often referred to as Stand-alone power systems, it works by generating electricity from solar panels and using it to charge a solar battery via a charger controller. Electricity is then converted using an inverter so that it can power your home or business appliances. By storing the electricity in solar batteries, it is possible to run your home or business exclusively using power from solar energy, even at night or during times when there is less than optimal sun exposure.

We use an Australian Made Selectronic Bi-Directional Inverter and BYD Battery to ensure a continuous power supply even during cloudy weather, this combination provides one of the most reliable and powerful off-grid systems in the world and comes in a range of sizes.

Key considerations when sizing off-grid solar systems

When designing an off grid solar system, we consider various factors to ensure it meets the property’s specifications and is a sustainable investment, including the size, usage, and solar exposure. Properly sizing your off-grid solar panel system is essential to meet your energy requirements.

We begin by estimating your daily energy consumption, including appliances, lighting, and other electrical devices. Based on this estimation, we calculate your daily total watt-hours (Wh) usage. We also take into account solar panel efficiency and the average number of sunlight hours in your location to determine the number of solar panels and battery capacity required. Oversizing the solar power system slightly can account for inefficiencies and variations in weather conditions.

Key considerations include:

Property Size

The property’s dimensions play a crucial role as they dictate the number of solar panels and batteries necessary to sustainably power your home.

Intended Use

It is essential to gauge the power requirements that will fuel your everyday life. Factors such as the number of people, heating/cooling preferences, the type and number of appliances are important considerations when determining a system size.

Sun Exposure

Your property’s solar exposure will determine the optimal placement for the off grid solar panels. Minimizing shading is important, be it a roof-top solar installation or a ground-mounted system.

Off-Grid Case Study

Our recent project on Off-Grid solar panel installation was for a Recreational Glamping site in Glenhope, Victoria. In this case, our client chose to go off-grid after discovering that the cost of establishing a connection to the electricity grid was prohibitively high. Our estimate indicated that a full off-grid solar system with two days of autonomy would cost significantly less than the grid connection.

Is going off-grid right for you?

Solar panels are the heart of any off-grid solar system. These panels consist of photovoltaic cells that convert sunlight into electricity through the photovoltaic effect. The number and size of off-grid solar panels needed depend on your energy requirements.

We will design and implement a tailored off grid solar system that perfectly aligns with your property’s needs. Our experts will explain and guide you every step of the way.

Benefits of Off-Grid Power Solutions

As electricity prices continue to rise and the cost of solar and lithium batteries decreases, more and more people are opting for off-grid solar systems as a sustainable energy solution. By combining PV panels, an inverter, and a solar battery, it is now possible to achieve independence from the grid.

Stand-alone solar systems generate energy from your solar panels and charge a solar battery, then use an inverter to provide this power to your home or even back to the grid. Using a solar battery gives the added benefit of storing the excess power and drawing from this energy reserve whenever required. You benefit by having more power back-up, freedom, savings, and flexibility.


Electricity generated is independent of the grid. More savings on rising energy bills. Electricity backup during blackouts and grid outages caused by severe weather.


Latest battery and inverter technologies are making off-grid power solutions more efficient and reliable.


Off-grid solar systems can be installed just about anywhere as they offer self-sufficient solutions.


The upfront costs of an off-grid solar system may be higher, but the long-term savings are undeniable.


With the recent advancements in battery and inverter technology, off-grid systems have become more expandable with increased battery storage capacity.

Additionally, off-grid solar systems will work anywhere you install them, even on a remote island in the middle of nowhere. This is useful in rural Australia, where running long cable connections for electricity from urban areas can be very costly.

Traditional electricity bills are a burden to homes and businesses. The upfront costs of an off-grid solar system may be higher, but the long-term savings are undeniable. System upgrades can be designed to be less complicated and you can even eliminate your electricity bills because the system pays for itself over time.
