Off-grid Solar System in New South Wales


off grid solar system nsw

The weather in New South Wales is ideal for solar power systems. The state has over 2,500 hours of sunshine per year, making New South Wales one of the best areas for solar energy. If you reside in New South Wales, and you’re considering an off-grid solar system for your home or business, then it is definitely worth investigating!

What is an off-grid solar system?

Off-grid systems are entirely self-sufficient and don’t rely on the power distribution grid. These systems will require battery banks to store the energy your solar panels generate so that your home or business can continue to operate outside of daylight hours.

The application of an off-grid solar system has long-been considered an unconventional option for some homeowners due to the space requirements and expenses that come with it. 


What Does an OFF-Grid Solar Power System Consists of?

You must carefully consider what goes into your PV system to successfully design an off-grid solar system. Every element offers an essential role, and understanding their purpose will help you make the most out of your investment. Below are the components that go into your off-grid photovoltaic system: 

PV Modules

Also known as solar panels, PV modules are built from various silicon-based photovoltaic cells. These PV modules power the PV system, producing DC electricity. The energy is stored in battery banks and will require an inverter to convert them into AC power, which is then used to power homes. You can either choose between black PV modules, monocrystalline, or polycrystalline – ranging from 275 to 370Wp. 


The controller is responsible for delivering energy from the PV modules to the battery bank. When the battery is almost full, the controller will recede in order to keep the necessary voltage. High-end controllers use Maximum Power Point Tracking (MPPT) for full utilization of solar panels. MPPTs are made of top-of-the-line circuit designs in order to produce the best power conversion. 

Off-grid Inverter

The off-grid inverter generates power from your battery, converting energy from DC to AC. These inverters are specially designed for high-capacity power systems. 

Solar Controller and Inverter

The primary role of a solar inverter is to convert DC electricity generated by solar panels to AC electricity. Getting the best solar inverter will influence the performance of your entire system. 


Off-grid solar systems will require specialised battery systems big enough to store energy for 48 hours or more. Hybrid grid-connected systems, on the other hand, use only low-cost batteries that can only generate energy for five to ten hours, depending on usage. 

How does Off Grid Solar Work?

  • When the sun hits your solar panels, it then creates an electric field that passes through the charge controller in order to run your batteries. 
  • When the battery is at its full capacity, electricity will then pass across the inverter charger. This process powers your household appliances. 
  • When using solar energy for your appliance, the DC battery bank releases DC power that passes across the inverter charger. This electricity is converted into 240V to power your 240V appliances. 
  • A high-quality off-grid diesel generator is an ideal backup power source. It can deliver energy security in cooler or rainy months of the year. 

Why Choose Off-Grid Solar Power Systems

Investing in off-grid solar power systems can save you from common issues experienced by many homeowners. Let us take a look at the top advantages of an off-grid solar power system:

Gives You Energy Independence

With an off-grid solar power system, you can finally be free from connecting to the power grid. This means your energy source is no longer linked to your energy grid. All you have to worry about is the energy you need to power your home.

Off-grid power systems are a good option for areas that frequently experience natural disasters, or an unreliable grid, resulting in long power outages. They are also beneficial to colder areas, as well as providing electricity to caravans and small cottages. 

Easy Installation

Since you no longer have to rely on the grid, the process of installation is now easier. All of the equipment necessary for your off-grid solar system will be contained within the system – you will no longer need complicated infrastructure to operate. 

Power Remote Locations

An off-grid solar system is an efficient option to power remote areas where electricity is too expensive or unavailable. With this option, you can seamlessly power your holiday homes that are far from urban areas. 

The Disadvantages of Off-Grid Solar Systems

The Disadvantages of Off-Grid Solar Systems

While there are many benefits to off-grid solar systems, there are also some disadvantages that should be considered before making a decision. Let us discuss the most important disadvantages of going off the grid with solar power. 

Initial Cost

One of the biggest disadvantages of off-grid solar systems is the initial cost. Installing an off-grid solar system can be very costly, and it may not be practical for everyone. If you are considering going off the grid, you should make sure that you are financially ready to cover the upfront costs.


Another downside of off-grid solar systems is that they need more maintenance compared to traditional grid-tied systems. This is because there are more components involved in an off-grid system, and every component must be maintained properly. If you do not have the budget to meet the necessary maintenance, then an off-grid solar system may not be the ideal option for you.

Reliance on the Sun

If you live in Australia then you will already know that not all days are sunny and the winter months can be long, cold, and dreary. This might mean that your system may not be able to generate all the power you need to keep you going through the night. Ensuring that your system is large enough to meet the demands of your home or business is paramount to maintaining energy independence. Relying on a fossil-fuel-run generator as a backup is not ideal.

If you are considering going off the grid, it is important to weigh all of the pros and cons prior to making a decision. Off-grid solar systems can be an excellent way to minimise your reliance on the traditional energy grid, but they come with some disadvantages that you should keep in mind before making the switch. 

Final Thoughts

The demand for electricity is consistently increasing now that the world has become more industrialised. This creates strain on traditional energy sources such as oil and coal, leading to environmental damage and increasing prices. As a result, people are switching to renewable options for cleaner and more sustainable sources. The good news is solar power, hydroelectricity, and wind power are excellent alternatives to fossil fuels and are becoming more affordable as technology progresses.
