The Top 5 Solar Panel Myths in Australia: Busted!


There are a bunch of myths floating around about solar panels in Australia… so we thought we’d put together five of the most common ones we hear about at Solar Market and bust them! These are in no particular order, so let’s get straight into it.

Myth #1: Solar Panels Are Too Expensive and Don’t Pay for Themselves

This one’s been around for years! When solar power first started to become more popular, it’s true that it was quite expensive. This meant that return-on-investment was also longer. However, installation prices have dropped by over 50% in Australia since 2012. As a result, solar is now an affordable investment that generally pays itself off in 3-5 years and sometimes less. Additionally, the Federal Government, as well as State and Territory Governments around Australia, have introduced a bunch of rebates over the years. These have reduced upfront costs and helped encourage many Aussies to make the switch. So, let’s check out how much you could get back in rebates here.

While the cost of solar power systems increases with size, you’ll be able to see your recommended system size based on your electricity needs and individual circumstances when you take our quick and easy solar quiz. Once you’re ready to get 3 free quotes, you’ll even be able to chat to installers more about which size would be best for you. However, if you do need a larger sized solar power system due to your electricity needs, your return-on-investment is unlikely to change that much.

Now… for feed-in tariffs. Feed-in tariffs allow you to earn extra credit on your electricity bill. Originally, they were offered at much higher rates than they are now, but there’s still some money to be made back from any electricity that your solar power system generates but does not get used. You can read more about feed-in tariffs here.

Myth #2: Solar Panels Will Keep My House Powered During a Blackout

How good would this one be if it were true? The only way to keep your home powered with solar during a blackout is through certain battery storage systems. If you’re not sure what these are or how they work, you can read more here.

In fact, here’s another thing you might not know. In Australia, solar power systems are actually required, by law, to shut off during a blackout! The reason behind this is safety; you wouldn’t want electricity running through powerlines while people are working on them… so in order to be extra safe, all systems are shut off in case work needs to be done on your street.

Myth #3: Solar Panels Don’t Work When It’s Cloudy or Too Hot

There are weather-related reasons as to why solar panels might stop working (like being covered in snow for a long period of time, for example), but when it comes to clouds or heat, this is not quite the case. Summer gets pretty hot around Australia, but solar panels still work during these times. However, when the temperature rises above 25 degrees Celsius, they do start to lose their efficiency. This difference in efficiency is usually not enough to notice on your power bills, so there’s no reason to stress about this.

Now, when it comes to clouds, the case is quite similar. On cloudy days, your solar power system will still generate electricity. However, this depends on a few factors, including the thickness of the clouds. You can usually expect your system’s output to reduce by 25-40% depending on the circumstances. So, if you live somewhere that regularly has super cloudy days, you can have a chat to your installer about it… because sometimes a higher quality solar panel will be more efficient than others.

Myth #4: Solar Panels Can’t Be Recycled

This was a widely believed myth, particularly when thin film solar panels were more popular. Recently, thin film panels have been smashed out of the ballpark by monocrystalline and polycrystalline solar panels, which have both completely taken over the market. However, it is in fact a myth that solar panels cannot be recycled… and solar panel recycling is a growing industry with a few plants now starting to pop up around Australia!

One of the first solar panel recycling plants in Australia was opened by Lotus Energy in Melbourne’s north. This particular plant claims to recycle every single element that makes up a solar power system – including mounting structures, inverters and cables – without the use of any chemicals. There are other companies in Australia that recycle old and/or damaged solar panels, including Reclaim PV.

Myth #5: Solar Panels Use More Energy to Make Compared to What They Produce

This is another myth that’s been around for a few years now… and a myth it shall remain!

According to LG Energy, once solar panels have been installed and are generating power, it only takes about 2 years to recover the energy used to make them. Additionally, the more that technology advances in the solar power industry, the more efficient that solar panels become. So, the number of years it takes to recover the energy used to make them is likely to reduce at some point down the track as panels become even more efficient and the technology continues to advance.

Understanding Batteries

Off-Grid Systems

For some households a battery system can be of great benefit and minimise a home’s reliance on the grid. However, it’s important to understand for a battery to be useful your solar system needs to be generating excess energy for the battery to store, which you can then use at night or when the sun is not out.

When selecting a battery, you’ll want to invest in a system that is most suited to your home and can drive the best return on investment (ROI). Despite a larger upfront cost, a higher quality battery may significantly increase your ROI.

    Battery systems start from $6,000 and costs can vary greatly based on the following factors:

  1. Cycle Life-Time

    The number of times a battery can fully charge and discharge.

  2. Battery Power (kW)

    How fast it can be charged or discharged.

  3. Storage Capacity (kWh)

    The maximum amount of energy a battery system can store.

  4. Battery Management System (BMS)

    An electronic ‘smart’ system that gathers data and manages the battery ensuring it does not overload or operate outside of its safe functioning zone..

  5. Inverter

    Battery systems require their own inverter if your solar system does not have a hybrid inverter.

  6. 'All-In-One Unit’

    A system which includes the battery, BMS and an inverter all in one unit.

  7. Warranty

    Length of time or cycles the battery system is under guarantee.

  8. Blackout Protection/Backup

    It’s important to note this is not a common feature of a battery system and could cost thousands of dollars to include. Blackout protection not only requires additional components but also a specialised installation and rewiring. For grid-connected homes, the cost for blackout protection can outweigh the benefit.

Additionally, if your purpose for adding battery is to go Off-Grid and become completely independent from the grid you will need to ensure your solar system can generate enough energy to power your home and your battery system is large enough to store this energy. For homes in metro areas going Off-grid is not cost effective and is only recommended for those in remote areas with limited access to the grid. Off-grid solar systems with battery start at approximately $30,000.
