Liberal Party re-election could benefit WA business by $40K


liberal party logo

If Western Australia’s Liberal Party takes the State election next month, they are poised to continue their support of renewable energy, with a yet to be introduced rebate for businesses.

The rebate is set to benefit businesses that install “large” solar systems and is valued up to $40,000.

If re-elected, the Liberal Party will run the 50MW program for three years unless the cap is reached earlier than that.  This would commence on July 1 this year and could benefit up to 500 rooftop systems.

The original funding will be sourced from a consolidated account, totaling $20 million.  The partial sale of Western Power will help extend the rebate and contribute an additional $20 million.

WA Premiere Colin Barnett is in favour of the scheme, calling it an effective cost saving measure.

While the Opposition leader, Mark McGowan, is publicly opposed to the sale of Western Power to “provide grants to multinational corporations to put in place solar panels”.

Mr. McGowan believes the companies should fully pay for them themselves.

Western Australian businesses have been slow to build business cases for installing solar,  compared to the other states and help Australia reach its goal of 23.5 % renewable by 2030.

Mike Nahan, Energy Minister, believes that the Liberal Party has delivered the most renewable energy during their state leadership than all combined previous WA governments.

Whether the Liberals continue their strong support of renewable energy or another government is tasked with promoting solar power, the facts are clearer than ever for businesses in WA and all over Australia: Solar will business save money on their rising electricity costs and sell back any unused power back to their local grid.

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.
