Record High Solar Panel Installation in 2020


Although 2020 saw most industries shutting up shop that didn’t stop the sun shining for the solar panel installation industry. Here’s how solar hit record high installations in 2020.

Key points:

  • In comparison to 2019, 39% more Aussies installed solar over 2020.­
  • Every Australian state recorded a ‘personal best’ in small-scale solar installations for December.
  • 2020 saw Aussies selecting bigger sized systems with the average system size coming in at 9kW.

New Solar Installation RecordsRenewable Energy

Although lockdowns caused disruptions across Australia, Aussies stuck at home invested in more solar energy than ever, lifting the uptake of solar panels to 39% from the pervious year. According to SunWiz, that’s almost 3,000MW of new solar installations going up on homes throughout 2020.

To put that into perspective, the electricity generated by these new solar panel installations was able to power 1.9 million homes.

In addition, 2020 ended with a bang, with 324MW of all solar installs registered in December.

Solar System Size Choices

As the price of solar continues to fall, SunWiz noted that through 2020 both residential and commercial solar customers were opting for larger system sizes. The average system size selection for 2020 came out at 9kW.

In previous years the 6.6kW has been the preferred model size. This shows that solar customers are looking for a more sustainable lifestyle.

As explained by Warwick Johnston, managing director of SunWiz, “As occurs each year, average system size also skyrocketed in December, as solar companies rushed to complete commercial installations before the STC subsidy reduced.”

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.
