Solar energy is the need of the hour to ensure zero emissions and preserve natural resources. This renewable source of energy not only saves you with money on electricity bills but also fetch you twice the bang on your buck by using and storing the previously generated solar energy.

According to a report formulated by the Centre for New Energy Technologies (C4NET) for Solar Victoria, households having solar panels are more likely to save up to an average of $1,073 a year. This value depends on the size and capacity of the solar system you have installed and the amount of energy generated.

If you are already saving money with solar, Solar Victoria is here to boost your savings with additional rebates on storage battery installation anywhere in Victoria. If you get an 11kwH storage battery installed in your home, you are eligible of saving approximately $650 on electricity bills every year. 

The estimated number of savings households are generating in Victoria with solar installation is estimated to be around $159 million in total for a year.

Benefits Offered By Solar Homes Program

With the introduction of the Solar Homes Program in 2018, Victorian households have managed to make a positive impact and are estimated to have:

  • Reduced the use of electricity from the grid by ~30%.
  • Reduced annual electricity bills by an average of $1073 per household.
  • Consumed 27% of the solar they generated.
  • Providing 38% of the total household electricity use.
  • Saved an average of two tonnes of CO2 emissions in a year.
  • Reduced CO2 emissions by an additional 5.6 tonnes through export to the grid.
  • Exported 10% more electricity than the average capacity.

The estimates listed above are the result of the data studied from households located in the AusNet Services distribution zone. When it comes to solar, savings can be improved if the costs of importing the electricity are reduced for every kWh of solar a household generates and imports to a grid.

The Solar Homes Program introduced by Solar Victoria has, till date, provided more than $270 million in rebates to make solar accessible, drive down the energy costs and tackle the climate change.

To make solar more affordable, Solar Victoria is continually introducing and altering their previous rebates for a bundle of more benefits. With the recent change in the rebate, Victorians can now access $3500 on solar batteries to boost their energy storage. This will make it easy for homeowners and businesses to benefit from solar power and also transfer the unused electricity to the grid with battery storage.

 Lily D’Ambrosio, the Minister for Solar Homes, informed that this change on battery rebate made by the government would motivate more consumers who are longing to have a solar system on their rooftop, get a quick solar installation to access the rebate on batteries.

 Before this rebate change was introduced, eligible home or business owners had to wait until they got a solar PV installed to access the battery rebate. Almost 4,000 home in Victoria has already benefitted from this battery rebate announcement.

 Why Is Now The Best Time To Install Batteries?

 With summers on the way and this new rebate change, now is the best time for the local households and businesses to get a solar powered system installed on their premises and gain full control of their energy bills with energy savings and added battery storage advantage.

 Along with enjoying the energy benefits, having a rooftop solar panel comes with cost savings on bills and electricity in the long run. A typical household can easily save hundreds of dollars a year with solar. Using this renewable energy, Victorian residents can generate their own electricity for reduced bills. By keeping the batteries charged, one can ensure a storage backup for power outages, less sunny or rainy days.

 Commitment To Clean Energy & Zero Net Emissions

 Solar Homes Program worth $1.3 billion started by The Victorian Government has managed to play a significant role in driving the clean energy revolution in the rural, suburb, and urban region, thereby helping thousands of families in saving dollars on energy bills.

 As per the guideline of the program, the estimated homes for solar panels, solar batteries, and solar hot water systems across the state are 770,000. Victorian residents can take advantage of the changed solar and battery rebates for extra savings on installation costs.

 With the introduction of battery rebates, Victoria is committed to meeting the goal of reduced emissions and utilizing renewable energy.

With the ever increasing electricity costs and pledge to net zero emissions by 2050, more and more homeowners are turning towards renewable sources of energy. Though entire Australia is opting for solar energy, Victorians are taking a major initiative in this solar revolution. Thousands of Victorians have replaced traditional electricity sources with solar energy, so much that, if the solar panels installed in Victoria are laid end-to-end, they’ll stretch all the way from Melbourne to Jakarta.

 Lily D’Ambrosio, the Minister for Solar Homes, Victoria, announced the latest figures of rooftop solar panels installed under the Solar Homes Program to be more than 3.16 million. Also, more than 180,000 homes and small businesses that have already applied for solar rebates of $334 million are urged to join this figure.

 She said, “Victorians continue to embrace renewable energy – they know solar is good for jobs, it’s good for the environment and good for bringing down power bills.”

 Switch To Solar For Low Cost Bills

 Since summers are on the way, energy requirements are going to touch the sky. So, it’s better to get prepared to tackle the hot weather with low cost renewable energy sources that saves you with money and resources in the long run.

 Now is the right time for the Victorian residents to consider investing in solar powered systems and take advantage of the $1,400 rooftop solar panel rebate decided by the Solar Victoria along with a $3500 solar battery rebate or up to $1,000 solar hot water rebate.

 In the recent announcement, the Victorian Government announced a $1000 rebate for upgrading old heaters with energy-efficient reverse-cycle air conditioners. In addition, individuals switching to a zero-emission vehicle gets a $3000 subsidy.

 Leaders In Climate Action & Renewable Energy

 With a $1.6 billion amount allocated for Clean Energy Package, Victoria has managed to become a global leader in climate action and renewable energy development. In the financial year 2019-20, the state connected 1.6 gigawatts of solar panels that are more than any other state in Australia.

 Till date, there are 21+ renewable energy projects with a combined capacity of 2,619 MW in progress and are getting commissioned shortly.

 Help Achieve Net Zero Emissions Target- Go Solar

 Victoria is leaving no stone unturned to achieve its goal of reducing emissions to half by 2030 and net zero emissions by 2050. Residents are going to play a significant role in this feast. With a number of solar rebates offered by the government, it’s the best time to take advantage.

 If you want to install solar panels on your household or business premises, Online Air and Solar is here to assist you. Talk to our accredited solar panel installers to discuss your goals and get started with the rooftop assessment and consultation. We are trusted by hundreds of Victorian residents and businesses for quality solar system installations that meet compliance. Our team will be more than happy to assist you.

Bigger Solar Systems Have Better Value For Money. Here's Why.

Why do large residential solar installations cost less than smaller ones?

Australian solar costs less per watt the bigger you go! This is because:

  1. Most of the install labour remains the same, whether the installation is big or small. 
  2. The STCs also known as ‘solar rebates’, is based on per panel and pays most of the actual panels’ wholesale cost.
  3. Most solar inverters cost less per watt the larger you buy

It's a win win situation.

The best reason for having as many solar panels as you can on your roof (given your budget) is – the money you save. If you have an unshaded roof, we recommend taking full advantage of this and buying a larger system for cheaper. 

And what if your system produces more energy than your house uses? Thanks to the solar feed-in tariff, you don’t have to worry about this – your excess energy will be automatically sent back to the grid and you will receive money from your electricity retailer for the excess energy your system produced. You will see all these details in your electricity bill. 

In saying this, you might as well invest in a larger system for cheaper and be able to accomodate for special situations like a power outage plus your money back from your electricity retailer for excess energy produced by your system. Larger systems are a win-win situation for you. 

A Bigger Solar System Requires A Little Extra Labour

When you ask for a bigger solar system, there may be only a little additional cost for extra labour. This is because of the number of panels of a roof. Installing solar panels on a roof are not easy and putting on 20 panels is a lot harder than 10. Apart from this, almost all other labour costs remain the same such as:

  1. Sales
  2. System design
  3. Getting to and from the site
  4. Setting up and carting away any required safety gear
  5. Solar inverter and cabling installation
  6. Switchboard wiring
  7. After-sales support
  8. Marketing

Bigger Is Better!

The reason we advice bigger solar systems is because of the amount that good quality solar systems have fallen in recent years with the help of government incentives. 

In the past when solar systems were expensive, it was probably right for people to find the right size of solar for their house. However, things are not the same anymore. We recommend taking advantage of government incentives to maximise your solar benefits. In addition to this, let your large solar system account for all types of situations such as night time, power outage etc. while receiving money back for any excess energy produced.

A Guide to Buying Solar Panels in 2021

If you’re sick of rising electricity prices and feeling like a slave to energy companies, then you’ve probably given solar energy more than a passing thought. We understand that the decision to go solar can be a tough one, especially without the right kind of research. It can also be a confusing one. That’s why we’ve gathered the following information to help you make an informed decision on what’s right for you!

Coming from solar industry experts ourselves, there has never been a better time to go solarWith electricity prices rising in recent years and decreasing solar costs, over 2 million Australian households are now enjoying clean, reliable energy – straight from the sun.

So what are the benefits of going solar?

For most people, the advantages of solar energy are obvious. In a global sense, harnessing the power of the sun’s rays to power our home is certainly better for the environment than other coal-generated forms of electricity.

From a financial perspective however, solar energy needs to be thought of as an investment. There’s certainly an upfront cost involved but the long-term benefits are clear. By using solar energy to power your home for all the sunlit hours of the day, you’re not drawing energy from the main grid and therefore, saving on your electricity bill.

On the other hand, if your home is producing excess energy, it gets sent back to the main grid and you receive a feed-in tariff from your energy company. The feed-in tariff pays you for excess electricity generated by your solar system which is not used in your home. This way you don’t have to worry about any excess energy your system produces because you will get back for it. 

To sum up, You may not be completely wiping out your energy bill in the first few months, but you’ll certainly be reducing it considerably allowing the system to pay for itself over time. 

How does on grid solar work?

On-grid solar means powering your home with solar energy for the hours in the day when the sun is shining. Without battery technology, an on-grid solar installation can only power your home while it is actually producing energy from the sun. Think of it like riding a bicycle on a flat stretch of road: while your legs are pedaling to produce energy, you keep on moving. If you stop producing that energy, you come to a stop.

Fortunately, unlike a bicycle with no backup system, your home is still connected to the main energy grid. So, at night time, or other times when your solar system isn’t producing energy, you can still power everything in your home. This is the energy consumption you’re still charged for by your energy provider. However, this sort of solar set up also comes with a feed-in tariff, which means your energy provider will actually pay you for the excess energy you produce and don’t use. This helps to off-set the cost of power you use when your solar system isn’t producing energy.

Let’s understand parts of a solar installation!

The most important component of any residential solar panel system is the array of panels up on your roof. During the daytime, your panels absorb the sunlight and convert it into clean electricity. Most people assume that it’s as simple as that, but don’t go forgetting the important role your inverter plays.

You see, to be used in the home, sunlight needs to be converted into the right type of electricity. An inverter takes direct current (aka DC) from the solar panels and turns it into alternating current (aka AC). This allows your solar energy to be used by the appliances in your home. The inverter usually sits on the exterior wall of your house or inside the garage.

Solar systems can be on-grid or off-grid. On-grid systems are connected to the electricity network. Off-grid means that your home produces and consumes electricity separate from the national network. If your solar energy system is connected to the grid, you can export your excess electricity to the grid and get rewarded for the contribution.

On the other hand, if your home is using more power than your panels can produce, you will draw power from the grid. That is why a smart meter is a necessary and important component. It measures how much electricity is exported and imported, so your energy retailer can provide an accurate quarterly bill.

You can also generate power during the day and save it for later or use it at night time. For this, you’ll need a battery. Recently, home batteries have become increasingly popular. With the advent of the Powerwall, energy storage has opened homeowners up to a world of possibilities when it comes to saving power.

Solar panels come in two forms – monocrystalline and polycrystalline. Both are perfectly fine for Australian conditions. The solar panels are installed, generally on your roof, and are used to capture the solar energy you’re going to use in your home. 

Several factors influence the efficiency of your solar panels such as positioning, shadowing, dirt and dust. But what if it’s going to rain? Do solar panels work on a cloudy day? The answer is yes. However, with a large number of types and efficiencies of panels, it can be hard to decide what is best for your house. If you require any help with making this decision, do not hesitate to give us a call on 1800 289 665.


Most people’s interest stops at the quality of their solar panels, but a high-quality solar system requires more than a high output array.

The power that comes from your solar panel is known as a DC or direct current.

To make solar work for your home, you need an inverter that transforms direct current into a 240V alternating current (AC), which is usable in the home. Without the inverter, your solar system wouldn’t be able to power your home. Our in house solar experts will help you decide which inverter is best for you. 


If you choose to direct your excess energy back to the grid, you’ll need a meter.

Net metering, NEM, or Net Energy Metering is a process of buying and selling solar power between you and your electricity provider.

Using this system, if your solar panels produce more energy than you need, you can choose to feed the excess into the grid and receive a credit on your account.

And if you consume more power than your solar is capable of producing, you can use the electricity from the grid.


To save your solar energy for later use, you will need to store it in a home battery. As little as five years ago, home batteries seemed like an unrealistic option for most homeowners. But today, thanks to reduced costs, better technology, and greater demand, batteries are more affordable than ever.

Basically, the battery makes the solar panel work for you 24/7, even at night, when the sun is no longer out. It will also provide energy during blackouts!

Online Air and Solar sells solar panels and battery storage systems for your home. We are also a certified Tesla installer. To buy the best and most efficient solar battery to save your energy for later use, please contact us on 1800 289 665 or email us at
