New Home-Builds To Receive Free Solar and Battery Packages


Mirvac a leading property group in Australia, along with Victoria Investments and Properties Pty Ltd, will provide those purchasing new home-builds in Woodlea, Victoria the opportunity of solar and battery storage as a standard feature in new homes. The offering comes under a scheme backed by the Clean Energy Finance Corporation (CEFC) and will be provided at no extra cost to a limited number of the Mirvac-designed townhouses starting in 2020.

Woodlea’s townhouses will be the first to be rolled out under the CEFC’s $90 million debt commitment to Mirvac, which they announced back in March 2018. 

The program has been put in place with the intention of fighting the rise of residential electricity prices and shift the “new normal” for houses being built in Australia to include solar and battery storage.

“Rising electricity costs is a concern for Victorians state-wide and although solar usage is on the rise, it’s not attainable for all households, we’re aiming to unlock these benefits for everyday Australians by essentially offering a $20,000 smart solar package as standard across our Mirvac townhouse offering” . Woodlea Project Director, Matthew Dean

CEFC CEO Ian Learmonth said “The investment was also designed to help battery storage technology gain traction in Australia, where it has been slow to take off – even in those states where storage is heavily discounted under government rebate schemes. We’d like to see integrated solar and battery storage in all suitable Australian households so they can benefit from the energy savings that this technology can provide.”

The solar and battery storage systems provided in the Mirvac homes are worth $20,000 and will include 5.1kW of solar panels, a 10kWh battery, 5kW inverter and smart controls. Solar PV systems of this size can cover 80% of a household’s electricity usage, which can equate to $1,500-$1,800 of savings per year through reduced bills.

“Some of the solar and storage equipped homes, might never receive another power bill again.” Mirvac Representative

“We are pleased that Mirvac is including these technologies as standard inclusions in these new homes so that Australian families can have greater control over their energy consumption and their carbon footprint from the day they move in.”  Mr Learmonth

Woodlea will launch its first solar townhouses in early 2020. For more information visit www.woodlea.com.au

While not all of us will be lucky enough to have a solar PV system and battery storage included in our new homes, when looking to build you can save on solar installation costs  by planning for your solar PV system in your building plans.

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.
