Off grid solar systems work by generating electricity from solar panels and storing it in batteries for use when the sun is not shining. In Australia, where there is plenty of sunshine, off-grid solar systems can provide a reliable and sustainable source of power for homes and businesses.
The basic components of an off grid solar system are:
- Solar panels: These convert sunlight into electricity.
- Batteries: These store the electricity generated by the solar panels. Deep-cycle batteries, which store extra electricity generated during sunny times for use during overcast days or at night, are commonly utilised in these solar battery systems.
- Inverter: This converts the stored DC electricity from the batteries into AC electricity, which can be used by household appliances and devices.
- Charge controller: This regulates the flow of electricity from the solar panels to the batteries, preventing them from being overcharged or discharged.
- Backup generator: This provides power in case the batteries run low or the solar panels are not generating enough electricity.
Off-grid solar systems can be designed to meet the specific needs of each household or business. The size of the solar array and the capacity of the battery bank will depend on the amount of electricity that is used on a daily basis.
Off-grid solar systems can be a great option for homes and businesses in remote areas that are not connected to the main power grid. They can also be a good choice for homes and businesses that want to reduce their reliance on grid electricity and save money on their energy bills.
- Sun shines on the solar panels or wind turns wind turbine blades, generating DC electricity
- The DC electricity feeds into a charge controller, otherwise known as a regulator, which controls the amount of charge
- Deep cycle batteries are charged
- 12 volt appliances can run directly off the batteries or the current routes through an inverter for conversion to 240V 50Hz AC electricity. This is suitable for running standard home appliances.

How to install an off-grid solar panel system
Installing an off-grid solar panel system in Australia allows you to generate clean, renewable energy and achieve energy independence. By following these steps, you can maximise the benefits of your solar panel investment and enjoy reliable, sustainable electricity.
Embrace the benefits of sustainable energy and contribute to a greener future while enjoying reliable electricity in even the most remote locations.
Sizing the system according to energy needs
Properly sizing your off-grid solar panel system is essential to meet your energy requirements. Begin by estimating your daily energy consumption, including appliances, lighting, and other electrical devices. Calculate the total watt-hours (Wh) needed per day based on this estimation. 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.
Installation tips for optimal performance
To achieve optimal performance with excess electricity from your off-grid solar panel system, consider the following installation tips:
- Position the solar panels in an area with maximum sunlight exposure, typically facing north in the southern hemisphere.
- Ensure panels are tilted at an angle that aligns with your latitude to capture the most sunlight throughout the year.
- Minimise shading by trimming surrounding trees or structures that may obstruct sunlight.
- Use appropriate wiring and connectors to maintain efficiency and prevent energy loss.
- Install the batteries in a cool, well-ventilated area to avoid overheating and extend their lifespan.
- Consult a qualified electrician to ensure compliance with local regulations and safety standards.
You can install your remote power system or off grid solar systems yourself or engage the services of an accredited off-grid installer.
If you wish to install your own system, in the case of solar power, the optimum for solar panels is that the glass face of the modules is positioned at 90 degrees to the sun for most of the day. In Sydney this angle would be approximately 30-40 degrees to the horizontal.

The pros and cons of wind power for off-grid living
Wind power has emerged as a popular option for generating off-grid electricity, offering a sustainable and renewable energy source. In the context of off-grid living in Australia, wind turbines present both advantages and disadvantages.
Pros of wind power for off-grid living
Renewable and clean energy grid: Wind power harnesses the natural energy of the wind, providing a clean and sustainable electricity source that reduces carbon emissions. With its vast open spaces and coastal regions in Australia, wind is abundant and can be a reliable energy resource.
Energy independence: By utilising wind power, off-grid households can become self-sufficient in terms of electricity production power consumption. This reduces reliance on the conventional power grid, making it a viable option for remote locations or areas with unreliable electricity infrastructure.
Cost savings: Over the long term, wind power can result in significant cost savings. Once the initial investment in wind turbines is made, the operational costs are relatively low. As the price of fossil fuels continues to rise, wind power becomes increasingly cost-competitive and economically attractive.
Cons of wind power for off-grid living
Variable wind speeds: Efficient power generation from wind turbines requires consistent and sufficiently strong winds. In certain regions of Australia, wind speeds may not meet the minimum threshold for optimal energy production, limiting the viability of wind power as a reliable off-grid energy source.
Initial investment: The upfront costs of purchasing and installing wind turbines can be substantial. While the long-term savings may outweigh the initial investment, the high upfront expenses can present a barrier for some off-grid households with limited financial resources.
Maintenance and lifespan: Wind turbines require regular maintenance to ensure optimal performance and longevity. Components such as bearings, blades, and control systems may need repairs or replacement over time. Maintaining wind turbines in remote off-grid locations can be challenging, requiring specialised expertise and logistical considerations.
If you are considering installing an off grid solar system in Australia, be sure to do your research and consult with a qualified solar installer. This will help you ensure that you choose the right system for your needs and budget.
