Are Batteries Really Worth After the New QLD Solar Battery Rebate?

This year, there has been a lot of discussion regarding the benefits of installing a battery to an existing solar panel system. Since it is a great way to save energy as well as energy bills and excess electricity, lots of Queensland residents are developing a great interest in it. But, is it worth to invest in solar system and batteries at this point of time? Let’s take a deeper look at it.

For those who are unaware and that may be a lot of us, Energy Minister of Queensland has announced the loan scheme and grants for the solar systems that will help up to 1500 household and small businesses to cut their power bills by storing solar energy.

You’d be surprised to know that almost half a million households in Queensland are producing energy from rooftop solar. To support this, the energy minister announced that from 19 November 2018, QLD residents can apply online for interest-free loans of up to $10, 000 and grants of $3000
to buy batteries or combine solar-battery systems.

With the attractive policies, interest-free loans and incentives, the government is looking forward to adding almost 1500-2500 battery storage systems in Queensland. But does install solar battery is really worth?

The Assessment of Battery Storage:

Batteries have gained tremendous interest amongst the Queenslanders thanks to the promise of becoming energy self-sufficient and having backup power, even in blackouts. Most people have mistaken this excess energy as the rate they pay their retail provider. However, here we need to take into account that this excess power could have been sent to the grid for a feed-in-credit.

Also, solar panels are a long-term investment. While installing a new solar system with a battery, at approximately 20,000 AUD, it can take eight years or more to see even the smallest of return. While the solar system takes 3 years to pay off, the battery may be sitting at 15 years.

For this reason, it sounds wise to forgo the battery and opt only for the solar system installation.

When Solar Batteries Will Be Considered As A Wise Investment?

  • Frequent grid outages can make solar batteries a practical solution
  • Installing solar batteries can lessen your dependence on fossil fuel. As compared to batteries, switching to solar has a far better impact on the environment.

Final Takeaway
Though the QLD solar battery rebate is beneficial for the grid, it still imposes very little financial advantage for the consumers. The QLD scheme is robust, but unfortunately, the payback period of the battery still doesn’t align for the customers.

It makes more sense to consider more solar panels over a solar battery. Remember – the battery can always be added later. Thus, there’s no need to rush into it now, just because the government is offering a rebate.

3kWh vs. 5kWh – Which Solar Panel System Do I Need?

The Sunshine State, Queensland has more than half a million roof-top solar systems installed and leads the nation in solar penetration. A perfect fitting for the sunshine state, Brisbane receives ample amount of sunshine every year.

Over 30% of the Brisbane homes have installed solar systems on their roofs – one of the highest rates of any of the capital cities of Australia. It costs somewhere between $3000 and $13000 to buy and new solar system installation in Brisbane. And with QLD solar rebates and incentives, interest-free solar loans and tax credit; there is no better time than now for installing solar PV system in Brisbane.

If you are a Brisbane resident and planning to install a solar system at your rooftop, one of the very first decisions that you’ll need to make is the capacity of the system to be installed.

Listed below are the few points that you need to know while considering solar in Brisbane.

  • The price of the solar panels in Brisbane starts from around $3,000.
  • Generous rebates are available.
  • Feed-in-Tariffs (FIT) pay you for the excess electricity you send to the grid.
  • You can expect the solar system in Brisbane to pay for themselves in 3-6 years.

Generally, the residential solar system market is classified out into 5 solar system sizes. They are:

  • 2 kWh solar system
  • 3 kWh solar system
  • 5 kWh solar system
  • 6 kWh solar system
  • 10 kWh solar system

The above classification is based on the size ratings of the solar inverter – one of the main parts of any solar system. Here, it is vital to note that the power capacity of the solar panels in Brisbane varies depending on the brand you select.

Solar System Is A Big Investment – Be Confident While Choosing One!

Nowadays, getting the most out of solar panels in Brisbane is related to “solar self-consumption” – using the energy directly in the home. This way, you can avoid the need of purchasing electricity from the grid at a rate between 18-35c/kWh (depending on where you are).  While on the other hand, if you export solar energy into the grid, you will earn only 6-8/kWh, which is not even half of the price you pay.  Thus, it’s highly advisable to buy a solar system that makes you self-sufficient.

While deciding on the size of the solar system, it depends on numerous factors such as the amount of energy you are going to use during the day, the available roof safe, the orientation of your roof and how much shading you have.

Amongst the above-mentioned 5 system sizes, 3kWh and 5kWh are the most popular sizes amongst the Brisbane residents. Which is the better investment – and why?

Smaller Systems Are Less Expensive

One of the major causes that a 3kW system is more popular than a 5kW system is – cost will certainly be lower. On an average, a 5kW system will cost approx $2000 more than a 3kW system.

Conventional Wisdom – 3kW Is Better Than 5kW for Maximising Self Consumption

It is generally believed that in comparison of a larger system, a smaller system will offer better value and returns. In fact, this advice is given by most of the reputable installers to their customers since Australia’s state-sponsored solar FIT programs were closed. The main reason behind this concept is that is it makes no sense in paying more for a system whose energy you can’t make greater use of.

Why Go For 5kw Solar System Instead Of 3kw Solar System?

Though a 5kW system is more expensive than compared to a 3kW system, it produces more energy too. It is found that if compare the increase in energy production, the increase in cost is disproportionately small. In short, it offers better value for money. Let’s take a detailed look at the benefits of going with the larger 5kW solar system:

  • More Solar Energy When Needed Most – Most Brisbane households use the greatest amount of energy in morning and evening. A large system will produce more energy during these time periods.
  • Room For Future Energy Growth – A larger system leaves you with space when it comes to the way of consuming energy. For instance, if you are starting up a home office or planning on having children, you’ll almost definitely be able to start using up the excess solar power at some point in the future.
  • More Energy Available For Batteries – If you aren’t able to afford buying battery storage for your home in the present but planning to get it in the future, then having a larger solar system will definitely be a winning situation. A large 5kW solar system will help ensure that you’ve got enough extra energy to be sent into the batteries, once they’re installed.

Payback Period:

The payback period or the ROI is almost similar for both the solar systems in Brisbane.  High-quality 3kW solar systems will pay back for itself in approx 3 years.  While on the solar system, a 5kW solar system will take around 2.5 – 4 years to pay for itself.

As installing solar panels in Brisbane offers an immediate ROI through utility bills. You’ll start saving from day one. Remember, that the less power you feed into the grid, the less time will be required to pay off your system.

Comparison between 3kWh and 5kWh:

3kWh Solar System in Brisbane 5kWh Solar System in Brisbane
·         9-12 solar panels and generates approx 5kW/day

 

·         80% of your energy is consumed and 20%  goes back to the grid

 

·         15m2 to 25m2 of roof space is required for installation.

 

·         Average cost – $3,490 to $5,600

 

·         Solar rebate is around $2,390

·         20 solar panels and generates approx 20.8kW/day

 

·         70% of your energy is consumed and 30%  goes back to the grid

 

·         20m2 to 40m2 of roof space is required for installation.

 

·         Average cost – $4,990 to $8,000

 

·         Solar rebate is around $3,990

 

The Final Verdict

When it comes to investment and its worthiness, both 3kW and 5kW solar systems are theoretically equal. From the above analysis, we can conclude that a 3kW system is perfect for the small working families with an energy bill of $220 or more/cycle. While on the other hand, a 5kW system is ideal for the medium or large families with electricity expense of $350 or more/cycle.

To be honest, we would recommend you to opt for a 5kW system. It is one of the most popular solar options amongst the Australians. Moreover, a 5kW is ideal for larger households and the major advantage is that you can easily get a payback within 4 years, (approx).

Though it’s more expensive than the other one, do take into account that a 5kW system is going to save and pay you more in the long run. Moreover, you’ll have more energy during peak times and also you can store that excess energy in the battery to get completely energy independent.
